Question

large trees like this are found in rainforests. how would a decrease in these trees impact the ecosystem?
a. decrease in temperatures
b. decrease in soil erosion
c. increase the amount of sun that reaches the ground
d. increase in habitats for other organisms

Explanation:

Large rainforest trees provide shade that cools the ecosystem; fewer trees mean less shade, so temperatures rise (eliminating A). Their roots and canopy reduce soil erosion; fewer trees lead to increased erosion (eliminating B). Their dense canopy blocks sunlight; fewer trees let more sun reach the ground (eliminating C). Fewer large trees reduce available habitats (like tree hollows, canopy space) for other organisms, so this habitat availability decreases, meaning the opposite option (D) is incorrect. The only valid impact is that less tree cover increases sunlight reaching the ground.

Answer:

C. increase the amount of sun that reaches the ground
