Detailed explanation-1: -Grasslands. Grasslands are the most useful biome for agriculture because the soils are generally deep and fertile. Almost one billion people rely on grasslands for their livelihood or as a food source.

Detailed explanation-2: -Aquatic biomes are probably the most important of all the biomes. Their medium, water, is a major natural resource. Water is the basis of life, it supports life, and countless species live in it for all or part of their lives. Freshwater biomes supply us with our drinking water and water for crop irrigation.

Detailed explanation-3: -Temperate grasslands have some of the darkest, richest soils in the world (not in wealth, but in nutrients). People who live in grassland regions often use these soils for farming. In North America we call temperate grasslands prairies.

Detailed explanation-4: -A temperate forest is a forest found between the tropical and boreal regions, located in the temperate zone. It is the second largest biome on our planet, covering 25% of the world’s forest area, only behind the boreal forest, which covers about 33%.
