What abiotic factors determine the type of terrestrial biome? why is the tropical rainforest the most diverse terrestrial biome? put the zones of freshwater lakes and ponds in order of most sunlight to least sunlight: profundal, littoral, limnetic. why do different biomes have different plant and animal species?

The abiotic factors that determine the type of terrestrial biome are sunlight, wind, rainfall, humidity, level of pollution etc.

Tropical rainforest is the most diverse terrestrial biome because of the availability of enough rainfall and sunlight.

Littoral, limnetic, profundal.

Different biomes have  different plant and animal species because they have different abiotic factors.

Explanation:

Abiotic factors like temperature, amount of sunlight, rainfall, humidity , level of pollution etc can determine the type of biome. Tropical rainforests are located at the tropical regions which receive greater amount of sunlight and rainfall. Availability of sunlight and rainfall in plenty supports diverse life forms making the tropical rainforests the most diverse terrestrial biome.

The   zones of freshwater lakes and ponds arranged in terms of maximum sunlight availability to minimum sunlight availability is littoral, limnetic, profundal. Littoral zone is the region nearest to the shore and receives maximum amount of sunlight. Limnetic zone doesn’t receive sunlight till the bottom.

Profundal zone is underwater and covered by mud and thus receives minimal amount of sunlight.The species of plants and animals that can be found in a biome depends on the conditions of the biome. Several abiotic factors are crucial in determining the type of a biome.

Thus two different biomes will have different species types as well.
