What would happen to a tropical rain forest if you remove just the big trees?

• When the big trees are gone the nutrient cycle gets disrupted.

• Acid rain bleaches the soil making it impossible to grow anything.

• Rain has no place go to so it pools and can grow into a thriving lake.

• The heat reflected off the open area creates an updraft for birds to hunt prey all day.
