Possibly a forest fire. That would leave the forest as a meadow or prairie, to start all over again.
A tropical rainforest
No, they are so close together that little light reaches the forest floor.
Such a forest is called a Tropical Rain Forest
The five major biomes are tundra, taiga, temperate deciduous forest, grasslands, and tropical rainforest. Each biome has distinct climate, fauna, and flora characteristics that differentiate it from the others.
Tropical and Subtropical Moist Broadleaf Forests. information: AND a little bit of savanna. just saying. np yo.
no humans would be able to survive on earth due to too little food
A tropical climate typically features high temperatures year-round, with little variation between seasons. These regions often experience high humidity levels and frequent rainfall, supporting lush and diverse ecosystems such as rainforests. Tropical climates are found near the equator and can have distinct wet and dry seasons.
The 2 biomes that are not in Canada are the tropical forest and the desert. The other 4 are definitley in Canada. *Edit* Actually Canada has a very little desert biome in southern B.C. so I think it could be tropical rain forest and chaparral. It depends which list of biomes you are choosing from.
Tropical Grassland
there actually be little to no trees and possibly we would all die
The dense canopy of trees in a tropical rainforest blocks out much of the sunlight, preventing it from reaching the ground. The canopy layers absorb and use the sunlight for photosynthesis, leaving little light to penetrate through to the lower levels. Additionally, the high humidity and constant cloud cover in tropical rainforests can further reduce the amount of sunlight that reaches the ground.
