AP BIOLOGY

Detailed explanation-1: -Aquatic Biomes are of two types marine and freshwater. Freshwater biomes are lotic and lentic ecosystems. Marine biomes are oceans and seas, estuaries, and coral reefs.

Detailed explanation-2: -The aquatic biome can be broken down into two basic areas, freshwater (i.e, ponds and rivers) and marine (i.e, oceans and estuaries).

Detailed explanation-3: -Aquatic biomes can be generally classified based on the amount of salt in the water. 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.

Detailed explanation-4: -In the ocean, the part of the pelagic zone over the continental shelf is called the neritic zone, and the rest of the pelagic zone is called the oceanic zone. The benthic zone is the bottom surface of a body of water. In the ocean, the benthic zone is divided into additional zones based on depth below sea level.
