The correct answer is:
c. It allows multiple organisms to share the same food source, providing alternative food options if one source is depleted.
This interconnection of food chains in a food web contributes to the stability of an ecosystem by ensuring that if one organism or food source is affected by a change (such as disease, environmental change, or resource depletion), other organisms can still survive by relying on alternative food sources. This diversity in feeding relationships helps maintain ecological balance and resilience.
