Biology Semester 1 Final Review - Ecosystem Dynamics

Front

What is exponential growth?

Back

A type of growth where the population size increases rapidly over time, typically represented by a J-shaped curve.

Front

What are limiting factors?

Back

Environmental conditions that restrict the growth, abundance, or distribution of a population within an ecosystem.

Front

What is a keystone species?

Back

A species that has a crucial role in maintaining the structure of an ecological community, influencing many other species.

Front

What is carrying capacity?

Back

The maximum number of individuals of a particular species that an environment can support sustainably.

Front

What is a predator-prey relationship?

Back

An interaction where one organism (the predator) hunts and consumes another organism (the prey).

Front

What is logistic growth?

Back

A type of growth that starts exponentially but slows as the population reaches carrying capacity, forming an S-shaped curve.

Front

What are biotic factors?

Back

Living components of an ecosystem that affect the population of organisms, such as competition, predation, and disease.

Front

What are abiotic factors?

Back

Non-living physical and chemical elements in the environment, such as temperature, water, and soil.

Front

What is a boom-bust cycle?

Back

A pattern of population growth characterized by rapid increases followed by sharp declines.

Front

What is a food chain?

Back

A linear sequence of organisms through which nutrients and energy pass as one organism eats another.
