Back

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

Front

What is immigration in the context of population ecology?

Back

Immigration is the movement of individuals into a population from other areas.

Front

What is emigration in population ecology?

Back

Emigration is the movement of individuals out of a population to other areas.

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 disease, competition, and predation.

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 and climate.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (e.g., plants, animals), while abiotic factors are non-living components (e.g., water, temperature).

Front

What role do herbivores play in a food web?

Back

Herbivores are primary consumers that obtain energy by eating plants, and they typically receive about 10% of the energy stored in the plants.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.

Front

What is the significance of a food web pyramid?

Back

A food web pyramid illustrates the flow of energy through different trophic levels in an ecosystem, showing how energy decreases as it moves up the pyramid.

Front

What is the concept of ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.
