Front

What are density-dependent factors?

Back

Density-dependent factors are environmental factors that affect a population's growth based on its density, such as food and shelter.

Front

Why is genetic diversity important for a species?

Back

Genetic diversity enhances a species' adaptability to changing environments and reduces the risk of extinction.

Front

What is the difference between competition and predation?

Back

Competition involves organisms fighting for resources, while predation involves one organism hunting and consuming another.

Symbiosis is a close relationship between two different species, which can be beneficial, neutral, or harmful.

Front

What is parasitism?

Back

Parasitism is a relationship where one organism benefits at the expense of another, often harming it.

Front

What is carrying capacity?

Back

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