Question

which two of the following are examples of competition in a forest ecosystem?
a bee pollinating flowers in the forest
tall trees blocking sunlight from smaller shrubs beneath them.
two bird species using the same type of tree cavity for nesting
a hawk catching and eating a mouse.

Explanation:

• Bee pollinating flowers: This is an example of mutualism (a symbiotic relationship where both species benefit), not competition. The bee gets nectar and the flower gets pollinated.
• Tall trees blocking sunlight from smaller shrubs: This is competition for a resource (sunlight). The tall trees and smaller shrubs are competing for the limited amount of sunlight in the forest ecosystem.
• Two bird species using the same tree cavity for nesting: This is competition for a resource (nesting site). The two bird species are competing for the same type of tree cavity which is a limited resource in the forest.
• Hawk catching and eating a mouse: This is predation (one organism hunts and eats another), not competition.

Answer:

B. Tall trees blocking sunlight from smaller shrubs beneath them, C. Two bird species using the same type of tree cavity for nesting
