Back

A group of organisms that belong to the same species and live in a particular place at the same time.

Front

What is inbreeding?

Back

Inbreeding is the mating of individuals who are closely related, which can lead to a reduction in genetic diversity.

Front

What is the carrying capacity of a population?

Back

The maximum sustainable population size given the available resources.

Front

What are some benefits of biodiversity to humans?

Back

Food, timber, medicines, and ecosystem services.

Front

What is exponential growth?

Back

Exponential growth is growth that becomes more rapid as the total number grows.

Front

What is genetic diversity?

Back

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species.

What is a community in ecological terms?

Back

A community is a group of different species that live together in one area.

Front

What is a niche?

Back

A niche is the role or function of an organism or species within an ecosystem.

Front

What factors can limit population growth?

Back

Factors include food availability, habitat space, predation, disease, and competition.

Front

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

Back

Density-dependent factors are influenced by population density (e.g., competition), while density-independent factors affect populations regardless of their size (e.g., natural disasters).
