What is secondary succession?

Back

Secondary succession is the process of ecological recovery that occurs in an area where a disturbance has destroyed a community but left the soil intact, such as after a forest fire.

Front

What is left behind after a forest fire in secondary succession?

Back

Soil is left behind after a forest fire.

What is a density-dependent limiting factor?

Back

A density-dependent limiting factor is a factor whose effects on the size or growth of a population vary with the population density.

Front

At which point does a density-dependent limiting factor have a greater impact?

Back

Point 3, as the population reaches its carrying capacity.

Front

What type of population growth is represented by a logistic growth curve?

Back

Logistic growth is a type of population growth that starts exponentially but slows as the population reaches the carrying capacity of the environment.

Front

What is intraspecific competition?

Back

Intraspecific competition is when individuals of the same species compete for resources.

Front

What is the climax community?

Back

The climax community is the final, stable community in an ecological succession that remains relatively unchanged until disrupted by an event.

Front

What is the difference between exponential growth and logistic growth?

Back

Exponential growth occurs when resources are unlimited, leading to a rapid increase in population size, while logistic growth occurs when resources are limited, leading to a stabilization of population size.

Front

What role do limiting factors play in population dynamics?

Back

Limiting factors restrict the growth of a population by reducing birth rates or increasing death rates.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages from pioneer species to a climax community.
