AP BIOLOGY

Detailed explanation-1: -A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome. However, scientists disagree on how many biomes exist.

Detailed explanation-2: -Organisms evolve adaptations that help them survive in the climate of the biome where they live. For example, in biomes with arid climates, plants may have special tissues for storing water. The desert animals also have adaptations for a dry climate.

Detailed explanation-3: -Biomes are a community of living organisms that have common characteristics for the environment they exist in. They are formed as a result of the living organism’s response to the physical climate.

Detailed explanation-4: -This happens by the process of natural selection. By natural selection, the nature of the species gradually changes to become adapted to the niche. If a species becomes very well adapted to its environment, and if the environment does not change, species can exist for a very long time before they become extinct.
