Ecological Succession, and Population Ecology

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, leading to a more stable community.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil and some organisms still remain.

What is exponential growth?

Back

Exponential growth is a pattern of population increase where the number of individuals grows at a constant rate, leading to a rapid increase in population size.

Front

What is logistic growth?

Back

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

Front

What are density-dependent limiting factors?

Back

Density-dependent limiting factors are factors that affect population size in relation to the population's density, such as competition, predation, and disease.

Front

What are density-independent limiting factors?

Back

Density-independent limiting factors are factors that affect population size regardless of the population's density, such as natural disasters like earthquakes.

Front

What is carrying capacity?

Back

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

Front

What is a population?

Back

A population is a group of individuals of the same species living in a specific area at the same time.

Front

What is a community in ecology?

Back

A community is a group of different species that live together in a particular area and interact with each other.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment.
