Question

scientists study rainforests as systems structured in vertical layers, or strata.
rainforest strata
overstory (or emergents) up to 50 meters
canopy 30 - 40 meters
under canopy 15 - 25 meters
ground layer 0 - 10 meters
how would a tree falling from the overstory layer most immediately affect the surrounding plants in the other three layers?
they would have access to more sunlight but less space.
they would have access to more sunlight and more space.
they would have access to less sunlight but more space.
they would have access to less sunlight and less space.

Explanation:

When a tree from the overstory layer falls, it removes an obstacle that was blocking sunlight. This allows more sunlight to reach the surrounding plants in the canopy, under - canopy, and ground layers. Also, the fallen tree creates more open space as it takes up less vertical space than when it was standing.

Answer:

They would have access to more sunlight and more space.
