AP BIOLOGY

Detailed explanation-1: -Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.

Detailed explanation-2: -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.

Detailed explanation-3: -The Earth’s biomes are categorized into two major groups: terrestrial and aquatic. Terrestrial biomes are based on land, while aquatic biomes include both ocean and freshwater biomes.

Detailed explanation-4: -Since changes in climate are gradual, the boundaries between biomes are not usually easy to define – they are transition zones. As a grassland biome becomes a forest biome, there is no sudden change from grass to forest. Instead there is a gradual change.
