Answer: B
Explanation:
Decomposers do exactly what they do in their name, they decompose matter and break them down so that their nutrients are recycled back into the soil. If it weren't for decomposers, there'd be dead waste everywhere and the soil would be depleted of nutrients. Hope this helped :)))
Decomposers help other organisms survive by putting nutrients into the soil
that plants use to grow.
Decomposers are group of organism that breaks down organic matter into
useable form for other organism or plants to grow.
They break down decaying or dead matters into smaller usable form.
This decomposition process adds nutrients to the soil and invariably aid the
growth of plants.
Examples of theses decomposers are fungi, bacteria, worms insect etc.
Therefore, decomposers put nutrients into the soil that plants use to grow.

When an oceanic plate collides with a continental plate:
A- The oceanic plate is forced beneath the continental plate
B- The oceanic plate is folded into mountain ranges
C- Both plates sink into the fluid mantle
D- Both plates are folded into mountain ranges
When an oceanic plate collides with a continental plate: - A- The oceanic plate is forced beneath the continental plate.
The oceanic plate is subducted under the continental plate due to the high density of the oceanic plate when an oceanic and a continental plate collide.
In this process, the oceanic plate will bend and slide under the other.This happens because the oceanic plate is denser (heavier) than the continental plate.This process is called subduction that forms a deep ocean trench at this subduction boundary.It forms a subduction zone.Thus, When an oceanic plate collides with a continental plate: - A- The oceanic plate is forced beneath the continental plate.

Radiation can be absorbed, transmitted, reflected, or scattered.
A good example to understand the nature of radiation is the Sun. The sun's radiation is absorbed, transmitted, reflected or scattered by the earth, in order to thrive and maintain a climate suitable for the habitat.
Absorption is also called the "interaction of light with matter". When this happens, absorption, light is converted into heat energy. This phenomenon can be explained through an example: during summer people avoid wearing black clothing since it absorbs light and gets very hot.

The theory of plate tectonics is a relatively new idea, developed in the mid-20th century following the discovery of tectonic features on sea-floors. Can you imagine our explanation of faults, earthquakes, mountains, and rifting before the plate tectonic revolution?
Answer: Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.
Explanation:
Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.
Answer:
boom ka boon sorry cant ill try
Explanation:
Plate tectonics has revolutionized virtually every discipline of the Earth sciences since the late 1960s and early 1970s. It has served as a unifying model or paradigm for explaining geologic phenomena that were formerly considered in unrelated fashion. Plate tectonics describes seismic activity, volcanism, mountain building, and various other Earth processes in terms of the structure and mechanical behaviour of a small number of enormous rigid plates thought to constitute the outer part of the planet (i.e., the lithosphere). This all-encompassing theory grew out of observations and ideas about continental drift and seafloor spreading.
In 1912 the German meteorologist Alfred Wegener proposed that throughout most of geologic time there was only one continental mass, which he named Pangaea. At some time during the Mesozoic Era, Pangaea fragmented and the parts began to drift apart. Westward drift of the Americas opened the Atlantic Ocean, and the Indian block drifted across the Equator to join with Asia. In 1937 the South African Alexander Du Toit modified Wegener’s hypothesis by suggesting the existence of two primordial continents: Laurasia in the north and Gondwanaland in the south. Aside from the congruency of continental shelf margins across the Atlantic, proponents of continental drift have amassed impressive geologic evidence to support their views. Similarities in fossil terrestrial organisms in pre-Cretaceous (older than about 146 million years) strata of Africa and South America and in pre-Jurassic rocks (older than about 200 million years) of

When an organism from one trophic level of a food chain is eaten by the organism at the next level up the chain, an average of about 10% of the energy from the first organism is available for use by the next organism. Where does the other 90% go at each level?
Answer:
The 90 % of energy is released in the ecosystem in the form of heat.
Explanation:
In each trophic levels of ecosystem, 90 percent of energy is lost as heat energy in the ecosystem while only 10 percent of energy is transferred from one trophic level to the next trophic level and becomes a part of that organism. For example, plants are the producer having 5000 kcal energy. When these plants are eaten by primary consumer such as cow, rabbit etc, about 500 kcal of energy is transferred to primary consumer and the rest of it is lost as heat energy.
The other 90% of the energy at each level of the food chain is lost to the environment, primarily through metabolic processes, heat loss, and waste products.
In ecology, the transfer of energy between trophic levels is governed by the principle of energy flow through an ecosystem. When energy enters the ecosystem through producers (usually plants), it is captured through photosynthesis. However, as energy moves through each trophic level, a significant amount is lost and is not available to the next level.
Here's a breakdown of where the energy goes:
1. Metabolic Processes: Organisms use energy for their life processes, such as respiration, digestion, and movement. Much of the ingested energy is used to maintain basic body functions and is lost as heat.
2. Heat Loss: The second law of thermodynamics states that in any energy exchange, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state. This essentially means that some energy is always transformed into heat and dissipated into the environment.
3. Waste Products: Not all parts of the organism are digestible. Some energy is lost in the form of feces and other waste products that are not consumed by the predator.
4. Undigested Parts: Some parts of the prey may not be consumed at all, such as bones, fur, or shells.
5. Growth and Reproduction: Some energy is invested in growth and the production of offspring, which may not be directly available to the predator.
The 10% rule is a simplification and the actual percentage can vary. Some ecosystems may have more efficient energy transfer, but generally, only about 10% of the energy is available to the next trophic level. This inefficiency in energy transfer limits the number of trophic levels in a food chain, typically to four or five. This limitation is known as the trophic pyramid of energy, with the largest amount of energy at the bottom (producers) and successively smaller amounts at each higher trophic level.

Explain why it is advantageous for organisms such as fungi and algae to
form mutualistic relationships.
Answer:
Each organism benefits from the other, because each organism provides something the other cannot get on its own.
Explanation:
Fungi and algae form mutualistic relationships because they eat decomposing material and provide protections to other organisms.
Mutualistic relationships between fungi and algae are advantageous because each organism provides a benefit to the other; fungi get nutrients from algae, and algae get a safe environment from fungi. Both organisms can thus survive in environments they otherwise couldn't.
Explanation:It's advantageous for organisms such as fungi and algae to form mutualistic relationships because they each offer something beneficial to the other. In a mutualistic relationship, both organisms benefit. For instance, fungi get photosynthesized nutrients from algae. On the other hand, algae get a safe, moist environment where they can grow, which is provided by the fungi. Through a mutualistic relationship, both algae and fungi can survive in environments where they might not be able to live independently. This type of relationship is a prime example of mutualistic symbiosis at play in the natural world.

After the Krebs cycle only a small portion of the energy of gluecose has been converted to atp. At this point the majority of usable energy contained in
Cellular respiration is a three-part process including glycolysis, the Krebs cycle, and electron transport chain, designed to extract energy from glucose. Only a small portion of the energy is converted to ATP after the Krebs cycle. Most of the energy is still carried by high-energy electrons sent to the electron transport chain.
Explanation:The process you're asking about is called cellular respiration and is used to extract usable energy from glucose. It is a three-part process involving glycolysis, the Krebs cycle, and the electron transport chain.
Glycolysis, which occurs in the cytoplasm of the cell, is the first stage. In this process, glucose is split into two three-carbon sugars, with the investment and subsequent production of 2 ATP per glucose molecule. Next, the Krebs cycle (or Citric Acid Cycle) takes place in the mitochondria and produces a small amount of ATP, but its main purpose is to provide high-energy electrons used in the next stage.
The electron transport chain is where most of the energy is produced. The high-energy electrons provided by the Krebs cycle are used to create a large amount of ATP as they are transported along a series of proteins. This whole process only extracts about 34 percent of the energy contained in glucose, with the rest being released as heat.
Therefore, it is correct that only a small portion of the energy of glucose has been converted to ATP after the Krebs cycle. Most of the energy is still in high-energy electrons passed on to the electron transport chain.
