What does species richness mean?

Back

Species richness is a measure of the number of different species present in an ecosystem.

Front

What is a density-independent limiting factor?

Back

A density-independent limiting factor is a factor that affects population size regardless of the population's density, such as natural disasters like earthquakes.

Front

What is the logistic growth model?

Back

The logistic growth model describes how a population grows rapidly at first and then levels off as it approaches the carrying capacity of its environment.

Front

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance, playing a critical role in maintaining the structure of an ecosystem.

Front

What is carrying capacity?

Back

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

Front

What is renewable resource?

Back

A renewable resource is a natural resource that can be replenished naturally over time, such as solar energy or timber.

Front

What is the difference between exponential and logistic growth?

Back

Exponential growth occurs when a population grows without any limits, while logistic growth occurs when growth slows as the population reaches the carrying capacity.

Front

What is a population?

Back

A population is a group of individuals of the same species living in a specific area at the same time.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment.
