APES Populations Part 1

Front

What are limiting factors in an ecosystem?

Back

Limiting factors are resources such as food, water, sunlight, shelter, and space that restrict the growth of a population.

Front

What is carrying capacity?

Back

Carrying capacity is the largest number of individuals of a population that the environment can support sustainably.

Front

What are the main properties of a population?

Back

The main properties of a population include density, dispersion, and size.

Front

What is a density-dependent limiting factor?

Back

Density-dependent limiting factors are those that affect a population's growth based on its size, such as competition and disease.

Front

What is a density-independent limiting factor?

Back

Density-independent limiting factors are those that affect a population regardless of its size, such as natural disasters.

Front

What happens to a population when the number of births exceeds the number of deaths?

Back

The population will increase.

Front

What is population density?

Back

Population density is the number of individuals of a species per unit area or volume.

Front

What is dispersion in a population?

Back

Dispersion refers to the way individuals are spaced within a given area, which can be clumped, uniform, or random.

Front

What is the lag phase in population growth?

Back

The lag phase is the initial period of slow growth in a population before it reaches its carrying capacity.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction.
