Summarize: Give at least one example of each of the following:
A major disturbance that the ecosystem was able to recover completely from.
A major disturbance that caused the ecosystem to collapse entirely, was when the snakes and the grass became diseased.
A major disturbance that caused the ecosystem to stabilize at a new equilibrium.
When there was an increase in the snakes and hawks.
A major disturbance that caused the ecosystem to completely collapse.
Having a population of grass that is diseased.
A major disturbance that almost caused a total collapse, but that the ecosystem was able to recover from eventually.
___________________________________________________________________
Answer:
A major disturbance that the ecosystem was able to recover completely from the grasses which is diseased.
Explanation:
If the grasses were diseased, the ecosystem will recover itself from this type of disturbance. If the population of snakes and hawks increases so the ecosystem will recover itself from this disturbance because snakes are the food of hawks so if the population of snakes increases so more food is available for hawks in the form of snakes and that's why population of hawks also increases and the population of snakes is controlled.
The disease outbreak among the trees, the ecosystem rebounded as new, disease-resistant tree variants grew and replaced the affected ones When the snakes and the grass became diseased, the ecosystem collapsed, as these key components couldn't support the food chain.
During the experiment, various changes were made to the ecosystem, leading to different outcomes:
A major disturbance that the ecosystem was able to recover completely from:
After an initial disturbance, where the trees experienced a disease outbreak, the ecosystem managed to recover entirely.
Over time, the tree population gradually shifted towards disease-resistant variants, leading to a balanced and healthy tree community that eventually restored the ecosystem's equilibrium.
A major disturbance that caused the ecosystem to collapse entirely:
The ecosystem suffered a catastrophic collapse when both the snake and grass populations became diseased.
Snakes play a crucial role in maintaining the herbivore population, and the grass serves as the primary food source for herbivores.
With these key components failing, the entire food chain collapsed, leading to an irreversible loss of biodiversity and ecosystem function.
A major disturbance that caused the ecosystem to stabilize at a new equilibrium:
An increase in the snake and hawk populations disrupted the ecosystem's balance initially.
However, after a period of adjustment, the predator-prey relationship reached a new equilibrium.
The increase in snakes led to reduced herbivore numbers, which, in turn, impacted the grass population.
This new balance ultimately stabilized, with snakes and hawks coexisting in harmony with their prey.
A major disturbance that caused the ecosystem to completely collapse:
The ecosystem suffered a catastrophic collapse when the grass population became diseased.
As grass serves as the foundation of the food chain, its deterioration led to the collapse of herbivores, predators, and ultimately the entire ecosystem.
A major disturbance that almost caused a total collapse but eventually recovered:
Initially, a reduction in herbivores nearly caused a collapse by impacting the grass population.

Through what process do green plants make their own food?
Answer:
photosynthesis
Explanation:
Green plants create their own food through photosynthesis, where sunlight, water, and carbon dioxide are converted into glucose and oxygen. Chlorophyll in the plants absorbs sunlight to drive this process. This transformation is essential for plant growth and provides oxygen for the environment.
Green plants make their own food through a process called photosynthesis. This chemical process involves using sunlight to convert carbon dioxide (CO₂) and water (H₂O) into glucose (C6H₁2O6) and oxygen (O₂). Here’s how photosynthesis works:
Sunlight is absorbed by a green pigment in the plant called chlorophyll.Carbon dioxide from the atmosphere enters the plant through small openings in the leaves called stomata.Water is absorbed by the plant's roots from the soil.When these ingredients are combined, they undergo a chemical reaction powered by sunlight to produce glucose, which serves as food for the plant, and oxygen, which is released into the atmosphere.

what is causing the bee population to decline?
Answer:
The main reasons for global bees-decline are industrial agriculture, parasites/pathogens and climate change. The loss of biodiversity, destruction of habitat and lack of forage due to monocultures and bee-killing pesticides are particular threats for honeybees and wild pollinators.
Explanation:
Bee populations are decreasing due to pesticides, habitat loss, parasites, viruses, and climate change.
The decline in bee populations can be attributed to a combination of factors including the use of pesticides, habitat loss, parasites such as the Varroa mite and the Nosema gut parasite, viruses like the acute paralysis virus, and climate change. In North America, honey bee populations have been particularly affected by a phenomenon called colony collapse disorder, which leads to significant losses of colonies, but the exact cause of this disorder remains under investigation. The loss of bees and other pollinators poses a serious risk to the production of many crops that rely on pollination.

Describe the process of homeostasis when body temperature rises too high. ASAP please <3
Answer:
"If blood temperature rises too high, this is sensed by specialized neurons in the hypothalamus of the brain. ... As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body."
Explanation:
just do this answer, I'm sure
good luck
A high body temperature causes the blood vessels to widen, the sweat glands to release liquid, and the body loses heat. The temperature of the body returns to normal as heat is dissipated into the surrounding air.
What is role of homeostasis in human body?Specialized neurons in the brain's hypothalamus can detect when blood temperature gets too high. More blood flows close to the body's surface when these blood arteries widen, and the body releases more heat.
The body must do numerous tasks continuously to maintain homeostasis. Its primary responsibilities include metabolizing food, reacting to changes in the body's environment, exchanging materials with the environment.
Therefore, homeostasis is the process which helps when body temperature rises too high.

A space probe lands on a planet with 1/2 the gravitational force as the earth. What happens
to the mass and weight of the space probe?
Final answer:
The mass of the space probe remains the same, but its weight will decrease on a planet with 1/2 the gravitational force as Earth.
Explanation:
When a space probe lands on a planet with 1/2 the gravitational force as the earth, the mass of the space probe remains the same. Mass is a measure of the amount of matter in an object, and it does not change with the gravitational force.
However, the weight of the space probe will be different. Weight is the force exerted on an object due to gravity. It is directly proportional to mass and the strength of the gravitational force. Since the gravitational force on the new planet is 1/2 of that on Earth, the weight of the space probe will also be 1/2 of what it was on Earth.
For example, if the space probe weighed 1000 N on Earth, it would weigh 500 N on the new planet.

a. autotrophs such as plants and algae
b. heterotrophs such as fish
c. heterotrophs such as snails
d. decomposers such as micro organisms
Final answer:
The correct option is d. decomposers such as microorganisms. Most minerals in an ecosystem are recycled by decomposers, organisms that release nutrients from dead matter and waste back into the environment for use by producers.
Explanation:
The minerals within an ecosystem are recycled and returned to the environment predominantly by the direct activities of organisms known as decomposers, such as microorganisms. These decomposers, which include fungi and bacteria, break down dead organic matter and waste, thereby releasing nutrients like nitrogen, phosphorus, potassium, and magnesium back into the environment. These nutrients are then made available for uptake by producers like plants and algae, completing the recycling process within the ecosystem.
What is a strategy prokaryotes to help them survive
Answer:
What is a strategy prokaryotes to help them survive?
Most prokaryotes have cell wall which helps them to protect itself against hypo and hyper-osmotic. also some bacteria have endospore which helps them to survive as well
Explanation:
Prokaryotes use various strategies to survive harsh conditions, such as protective cell walls, forming endospores, and diverse metabolisms allowing them to utilize substances like hydrogen sulfide. The CRISPR-Cas immunity system and specialized adaptations like growth appendages for oxygen sensing further highlight their resilient nature.
Survival Strategies of Prokaryotes:
Prokaryotes have developed various survival strategies to adapt to a wide range of environmental conditions, making them incredibly versatile organisms. For example, nearly all prokaryotes possess a cell wall, which is a critical structure that provides protection in hypo- and hyper-osmotic situations. Additionally, certain soil bacteria can form endospores that are capable of withstanding extreme heat and drought, ensuring their survival during unfavorable conditions. These resilience mechanisms contribute to the dominance of prokaryotes in both terrestrial and aquatic ecosystems.
Moreover, prokaryotes exhibit a broad range of metabolisms that determine their habitats. They can utilize various substances, such as hydrogen sulfide (despite it being toxic to animals), to produce ATP for energy. Furthermore, some prokaryotes possess unique mechanisms such as CRISPR-Cas systems for providing immunity against viral infections. Others, like the bacterium Shewanella, demonstrate specialized adaptations like growing long appendages to seek out limited oxygen supply in their deep-sea habitats, a process that also allows them to digest toxic waste and even generate electricity.
These adaptive strategies firmly establish prokaryotes as vital components of the biosphere, contributing significantly to life-supporting processes and displaying remarkable abilities to adjust to and thrive in diverse and sometimes extreme environmental conditions.
