Limiting factors and carrying capacity

Front

What is a biotic limiting factor?

Back

A biotic limiting factor is a living component of an ecosystem that affects the population size of organisms, such as food availability.

What is the carrying capacity of an ecosystem?

Back

The carrying capacity is the maximum number of individuals of a particular species that an ecosystem can sustainably support.

Front

What are abiotic limiting factors?

Back

Abiotic limiting factors are non-living components of an ecosystem that affect population sizes, such as water, space, and oxygen.

Define carrying capacity in ecological terms.

Back

Carrying capacity refers to the maximum population size of a species that an environment can sustain indefinitely without degrading the habitat.

Front

What happens when a population exceeds its carrying capacity?

Back

When a population exceeds its carrying capacity, it can lead to resource depletion, increased competition, and ultimately a decline in population size.

Give an example of a biotic factor that can limit population growth.

Back

Food availability is a biotic factor that can limit population growth by restricting the number of individuals that can survive and reproduce.

What is the relationship between carrying capacity and population density?

Back

Carrying capacity is influenced by population density; as density increases, resources may become limited, affecting the carrying capacity.

How can human activities impact the carrying capacity of an ecosystem?

Back

Human activities such as deforestation, pollution, and urbanization can reduce the carrying capacity by degrading habitats and depleting resources.
