AP BIOLOGY

Detailed explanation-1: -According to the three cell convection model of each hemisphere the Earth neatly separates itself into three distinct climate zones; the polar, temperate, and the tropical zones.

Detailed explanation-2: -Biomes can be classified into three types, namely terrestrial, freshwater biomes and marine biomes. Terrestrial biomes include grasslands, deserts, tropical forests. Freshwater biomes include polar freshwaters, large lakes, tropical and sub-tropical coastal rivers, temperate coastal rivers and much more.

Detailed explanation-3: -The three major forest biomes are temperate forests, tropical forests, and boreal forests (also known as the taiga). These forest types occur at different latitudes, and therefore experience different climatic conditions.

Detailed explanation-4: -A biome is a climate zone and the plants and animals that live in it. The Koppen classification system divides climates into five major types and many subtypes based on temperature and humidity characteristics. A microclimate has different climate conditions from the surrounding regions.
