Orchids are flowering plants that depend on bees for pollination.
A population of orchids in a rainforest has reached its carrying capacity.
The size of the rainforest's bee population is a limiting factor of the orchid population.
What will happen to the orchids' carrying capacity if the rainforest's bee population decreases?

A. The carrying capacity will not change because it is a constant property of a species.

B. The carrying capacity will not change because it is a constant property of an ecosystem.

C. The carrying capacity will decrease because the level of the limiting factor decreases.

D. The carrying capacity will increase because the level of the limiting factor decreases.
