What are the three major factors that affect the earth’s biomes?

Altitude:Temperature degrees decreases by 1oc for every 100 meters in height. so the top of a mountain is covered in snow, even know its near the equator. Closer to the latitude the warmer it is and the further away the colder it is.

Weather because weather effects where plants may grow in some places. like the rain forest rains a lot and their is a lot of vegetation but in the desert it barley rains and their is close to no plans and animals their.

Hope this makes sense!
ask me for more help if needed

Ibelieve the answer is (a) true.
