Let's start off with the Tropical Rainforest. The tropical rainforest is humid and very rainy. There is also a wide variety of animals in the rainforest, also known as biodiversity.
In the Taiga, think of it as a cold desert. The taiga is very cold and dry. There is not that much biodiversity in this area.
The Temperate Forest is basically in the middle of these two. The forest has hot summers and cold winters, and has some biodiversity. There are some trees here, but not as much as the tropical rainforest.
Hope I helped some! Comment if you need anymore help.
