What is carrying capacity?

Back

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

Front

Which environment is expected to have the most biodiversity?

Back

Tropical Rainforest is expected to have the most biodiversity due to its warm climate, abundant rainfall, and variety of habitats.

Front

What type of population growth is illustrated by a J-shaped curve?

Back

Exponential growth is illustrated by a J-shaped curve, indicating that the population size increases rapidly under ideal conditions.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of species replacements.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of species, genetic diversity, and ecosystem diversity.

Front

What factors can affect population growth?

Back

Factors affecting population growth include birth rates, death rates, immigration, emigration, and limiting factors like food and space.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic components.
