Front

What is a heterotroph?

Back

An organism that cannot make its own food and relies on other organisms for nutrition.

Front

What is an autotroph?

Back

An organism that can produce its own food, typically through photosynthesis.

Front

What is a logistic graph?

Back

An S-shaped curve that represents population growth that levels off as it approaches carrying capacity.

Front

What is an exponential graph?

Back

A graph that shows population growth without limits, resulting in a J-shaped curve.

Front

What is a density-dependent limit?

Back

Factors that affect population growth based on the population size, such as food availability and disease.

Front

What is a climax point in ecology?

Back

The final stage of ecological succession, where a stable community is established.

Front

What is the difference between a producer and a consumer?

Back

Producers create their own food (autotrophs), while consumers (heterotrophs) rely on other organisms for food.
