Population _ Aquatic Biology Review

Front

What happens to a population when it grows past the ecosystem's carrying capacity?

Back

The population starts to die off to return to carrying capacity.

Front

What is a limiting factor?

Back

A limiting factor is something that stops a population from growing large.

Front

What can increase the carrying capacity of an ecosystem?

Back

An increase in available food can increase the carrying capacity.

Front

What happens to the growth of a population if the number of births equals the number of deaths?

Back

The growth of the population will stay the same.

Front

How does competition for resources affect the carrying capacity of an ecosystem?

Back

Competition for resources decreases the carrying capacity.

Front

Define carrying capacity.

Back

Carrying capacity is the maximum number of individuals of a species that an environment can support sustainably.

Front

What is the role of predators in an ecosystem?

Back

Predators help control the population of prey species, maintaining balance in the ecosystem.

Front

What are abiotic factors?

Back

Abiotic factors are non-living components of an ecosystem, such as water, sunlight, and temperature.

Front

How does disease affect population growth?

Back

Disease can decrease population growth by increasing mortality rates.

Front

What is the difference between density-dependent and density-independent factors?

Back

Density-dependent factors affect population growth based on population size, while density-independent factors affect growth regardless of size.
