What is a population?

Back

A population is a group of individuals of the same species that live in a specific area.

What is the energy transfer efficiency between trophic levels?

Back

Energy transfer between trophic levels is typically about 10%, meaning if there is 1000 Kcal in producers, there will be about 100 Kcal available to herbivores.

What is exponential growth in populations?

Back

Exponential growth occurs when a population grows at a constant rate, resulting in a J-shaped curve when graphed.

Front

What is immigration?

Back

Immigration is the movement of individuals into a population from another area.

Front

What is emigration?

Back

Emigration is the movement of individuals out of a population to another area.

Front

What factors can lead to population decline?

Back

Factors such as habitat loss, predation, disease, and competition can lead to population decline.

Front

What is carrying capacity?

Back

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

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that accounts for resource limitations, resulting in an S-shaped curve.

Front

What are r-strategists?

Back

R-strategists are species that produce many offspring but invest little in their care, often found in unstable environments.
