What would be an example of a limiting factor in an ecosystem?

• A. Availability of food
• B. Geographical location
• C. Species diversity
• D. Symbiosis

Answer: (A)

A limiting factor in an ecosystem is any resource or condition that restricts the growth, abundance, or distribution of a population within that ecosystem. The availability of food serves as a critical limiting factor because it directly influences the survival and reproduction of organisms. When food resources are scarce, populations may decline as individuals struggle to obtain enough energy to survive, leading to increased competition, changes in population dynamics, and, in severe cases, starvation. In contrast, geographical location, while it can influence the types of organisms that can thrive in an area, is not a resource that directly limits a population's growth. Species diversity refers to the variety of different species within an ecosystem and, while important for ecological balance, does not directly limit the population size of individual species. Symbiosis involves interactions between species, which can be beneficial or harmful, but does not inherently serve as a limiting factor in the same way that resource availability does. Thus, the availability of food is a clear example of a limiting factor as it is a fundamental requirement for sustaining life within an ecosystem.
