AP BIOLOGY

Detailed explanation-1: -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-2: -Marine regions cover about three-fourths of the Earth’s surface and include oceans, coral reefs, and estuaries. Marine algae supply much of the world’s oxygen supply and take in a huge amount of atmospheric carbon dioxide. The evaporation of the seawater provides rainwater for the land.

Detailed explanation-3: -Biomes allow the development of biological diversity, providing vital resources for subsistence such as oxygen, carbon and raw materials such as food or other products-a set of benefits called “ecosystem services”.

Detailed explanation-4: -Freshwater biomes have less than 1% salt and are typical of ponds and lakes, streams and rivers, and wetlands. Marine biomes have more salt and are characteristic of the oceans, coral reefs, and estuaries. Most aquatic organisms do not have to deal with extremes of temperature or moisture.

Detailed explanation-5: -Marine biomes are further divided into coral reefs, seas and ocean biomes, and estuaries biomes. Freshwater biomes are lakes and ponds, rivers and streams, and wetland biomes. The aquatic world of freshwater is influenced by soils in the surrounding areas, the pattern and speed of water flow, and the local climate.
