AP BIOLOGY

Detailed explanation-1: -During harsh winters, animals of the taiga have adaptations such as the ability to change color to avoid predators. Vegetation in biomes where water is scarce consists predominantly of coniferous trees. In the tundra, the frozen layer of soil just beneath the surface is called the permafrost.

Detailed explanation-2: -Some adaptations that animals have for living in the taiga are migration, hibernation, thick fur, large paws, and camouflage.

Detailed explanation-3: -The tundra is a fragile biome because conditions are severe, and the ecosystem is easily disrupted. Chaparral fires are beneficial because they destroy trees that compete for light and space. Tropical rain forests are resistant to change because the plants contain so many nutrients.

Detailed explanation-4: -Permafrost is a permanently frozen layer on or under Earth’s surface. It consists of soil, gravel, and sand, usually bound together by ice. Permafrost usually remains at or below 0°C (32ºF) for at least two years. Permafrost can be found on land and below the ocean floor.

Detailed explanation-5: -Biomes are described by their vegetation because plants that grow in an area determine the other organisms that can live there. Plants in a particular biome have characteristics, specialized structures, or adaptations that allow the plants to survive in that biome. These adaptations include size, shape, and color.
