CAN SOMEONE PLEASE HELP ME WITH THIS SCIENCE QUESTION THANK YOU!! (Explain how you got the answer)

D. Precipitation

Explanation:

Precipitation is the amount of rain that an area gets if we look at all major biomes in the world we can see that many of them only exist around areas with certain weather patterns.

The rainforest biome exists around the equator where there is a ton of rain and the climate is humid.

The desert biome tends to be around the 30 to -30 degree latitude lines where they is little rain but a lot of sun.

The deciduous forest biome exists in areas with moderate rain and sun.

The amount of water an area gets dictates the plant life that it can support and thus the animals that rely on plants will naturally adapt to the surrounding climate. Without water there would be few plants, with few plants there would be few animals.

they deliver oxygen to the blood
