Question

How do dependent limiting factors affect populations? (cause and effect)

a) Dependent limiting factors increase population growth by providing necessary resources.
b) Dependent limiting factors reduce competition within a population, leading to overpopulation.
c) Dependent limiting factors lead to population decline by limiting essential resources or increasing predation.
d) Dependent limiting factors have no significant impact on population dynamics.

Answer 1

Dependent limiting factors lead to population decline by limiting essential resources or increasing predation, thereby affecting population growth and maintaining balance in ecosystems.

Step-by-step explanation:

Dependent limiting factors affect populations by leading to a decline in population when essential resources are limited or when predation increases. This cause and effect relationship is crucial to understanding population dynamics. When a population encounters limiting factors such as a low food supply or insufficient space, the impact on the population depends on its density. Large populations may experience a decline due to increased competition for these scarce resources, whereas smaller populations might be less affected initially. Moreover, in predator-prey relationships, an increase in the prey population can lead to an increase in the predator population. Conversely, a decrease in the prey can cause the predator population to decline, showcasing how the prey population can be a limiting factor.

Therefore, the correct answer to the question is: c) Dependent limiting factors lead to population decline by limiting essential resources or increasing predation. These factors contribute to regulated growth rates, helping to prevent overpopulation and extinction.
