Front

What is exponential growth?

Back

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

Front

What is primary succession?

Back

The process of ecological change that occurs in an area where no soil exists, leading to the establishment of a biological community.

Front

Why does primary succession take longer to reach a climax community?

Back

Because primary succession does not have soil initially, which is necessary for plant growth.

Front

How does carbon move through an ecosystem?

Back

Carbon moves through the food chain, starting from producers like plants to consumers like herbivores and carnivores.

Front

What do the arrows in an ecosystem diagram represent?

Back

The direction of energy flow between organisms.

Front

What is a climax community?

Back

A stable and mature ecological community that has reached the final stage of succession.

Front

What is logistic growth?

Back

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

Front

What is carrying capacity?

Back

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

Front

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

Back

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

Front

What role do producers play in an ecosystem?

Back

Producers, like plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.
