Environmental pressure:
Pressures resulting from human activities which bring about changes in the state of the environment.
Environmental pressure for a rabbit:Damages caused by overgrazing native and sown pastures, leading to loss of plant biodiversity and reduced crop yields.
Environmental pressure for a cactus:Cactus species were under pressure from human activity, such as illegal trading, agriculture and aquaculture as well as land-use change.
Environmental pressure for a shark:Sharks must acquire food, escape predators, find mating partners and ensure the survival of their offspring.
Environmental pressure for a giraffe:Giraffes are quickly losing their living spaces.

Environmental pressures for a rabbit include food scarcity and survival from predators, for a cactus it's primarily arid conditions with scarce water, sharks face pressures such as overfishing and climate change, and giraffes deal with a changing climate affecting vegetation and human encroachment on their habitat.
Explanation:
Environmental pressures are factors in an organism's habitat that can affect its survival. For a rabbit, these pressures may include food scarcity, predators, extreme weather conditions or changes in habitat due to human activities (for example, agriculture or construction). The rabbit's ability to hide or blend into its environment can be an important adaptation to these pressures.
For a cactus, environmental pressures consist primarily of arid conditions with sparse water resources. A crucial adaptation is its ability to store large amounts of water. Human activities that cause desertification or changes to soil conditions can also be environmental pressures.
Sharks face pressures such as overfishing, climate change that affects the temperature and acidity of ocean waters, and loss of prey due to changes in the ecosystem. Some sharks are adapted to withstand deep ocean pressure, but disturbances to their habitat present a significant threat.
Finally, for the giraffe, environmental pressures can include a changing climate that affects the types and availability of vegetation they eat, water scarcity, and predation. Human encroachment on their habitat through activities like logging is another key pressure. Their long necks, an evolutionary adaptation, aid in reaching food sources otherwise inaccessible.

D. Marsh
Answer:
bog
Explanation: for the boyzzz bby
Bog freshwater ecosystem is least productive, because of its stability, or should we say stagnant variety, the freshwater bog ecosystem is the least productive, hence option C is correct.
What is freshwater ecosystem?Aquatic habitats on Earth are divided into freshwater ecosystems. They consist of marshes, rivers, streams, lakes, ponds, rivers, streams, and wetlands.
They can be compared to marine environments, which contain more salt than terrestrial ecosystems.
The least fruitful environment is the “bog freshwater” ecosystem. This form of ecosystem includes evergreen trees, shrubs, and shrubbery as well as a floor that is covered in a thick layer of sphagnum moss.
Therefore, bog freshwater ecosystem is the least productive.

Explanation:
Scientist who study climate changes are concerned that global warming may increase the frequency or intensity of tropical cyclones. What predicted effect of global warming would increase the destructive power of hurricans?
Global warming and hurricanes
Explanation:
Global warming and climate change lead to erratic and more destructive patterns in natural disasters like hurricanes.
Increasing global temperature has also increased the frequency of highly devastating major hurricanes. The major hurricanes which occurred once in many years or even once in a century, now occurs very frequently like once in a decade or less.
Global warming increases the sea surface temperature which in turn increases the sea level. This piling of water leads to storm surges along coastal lands.
With increasing sea surface temperature and high humidity, increases the hurricane intensity. Further, increased temperature leads to high wind at varying altitude over the sea surfaces which causes vertical wind shear that can worsen the hurricane effects.
The predicted effect of global warming would increase the destructive power of hurricanes is that warmer sea surface temperatures intensifies tropical storm wind speeds.
What is Global warming?This is defined as long-term heating of Earth's climate system sa result of the release of greenhouse gases.
This causes sea temperature to increase which brings about an increase in the intensity of tropical storm wind speeds.

Which factors are used to characterize a biome, such as the desert, tropical rain forest, or temperate grasslands? Select all of the answers that apply.
Answer:
Temperature and precipitation
Explanation:
Biomes are characterized based on dominant vegetation types in regions with similar climatic conditions. Key factors in shaping biomes include temperature and precipitation. These conditions influence the composition of plant and animal communities, and the concept applies to both terrestrial and aquatic biomes.
Explanation:
The biome, a large-scale community of organisms, is primarily characterized based on the dominant plant types that exist in geographic regions with similar climatic conditions. The Earth showcases both terrestrial and aquatic biomes. The eight major terrestrial biomes include tropical wet forests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra.
Temperature and precipitation, and variations in both of these abiotic factors, are key in shaping the composition of animal and plant communities in these biomes. For instance, biomes like temperate grasslands and forests have distinct seasons, experiencing both cold and hot weather throughout the year. In contrast, biomes such as the desert and tundra have low primary productivity due to harsh temperatures and scarcity of water.
Different vegetation and animal life can exist in geographically distinct areas with similar climates due to these factors. Apart from terrestrial biomes, there are also the aquatic biomes which include both saltwater and freshwater ecosystems, with their structuring influenced by different abiotic factors such as sunlight, density, and temperature.

What is Punnett Square?Punnett square is indeed a graphical representation of the potential genotypes of an offspring that results from a certain mating event. The genetic make-up of the parents must be known in order to construct this graphical representation.
This square-shaped graphic is used to predict genotypes in breeding or cross experiments. In 1905, Reginald C. Punnett invented this method. This is used by biologists to determine the probability that a specialized gene will be passed on to progeny.
According to the Punnett Square, 50% of the offspring in the case above will have attached earlobes.

Producers are organisms that produce their own food and not depends on any other organism by the process of photosynthesis such as algae. Primary organisms on the other hand directly depend on the producers for their food and often gt killed by secondary consumers.
Freshwater snails are the perfect example of the primary consumer as they get their food and energy from algae and are the primary source of food and energy for small fishes. The type of food that should be eaten in limited quantities would be fats. Too much of certain types of fat can lead to other health problems.
