EOC Blitz Review - Limiting Factors Examples

Front

What is a limiting factor in an ecosystem?

Back

A limiting factor is a condition or resource that restricts the growth, abundance, or distribution of an organism or a population within an ecosystem.

Front

What are abiotic factors?

Back

Abiotic factors are non-living physical and chemical elements in the environment, such as sunlight, temperature, water, and soil.

Front

What are biotic factors?

Back

Biotic factors are living components of an ecosystem, including plants, animals, and microorganisms that affect the population of other organisms.

Front

What is density-dependent limiting factor?

Back

Density-dependent limiting factors are factors whose effects on the size or growth of a population vary with the population density, such as competition, predation, and disease.

Front

What is density-independent limiting factor?

Back

Density-independent limiting factors are factors that affect population size regardless of the population's density, such as natural disasters, climate changes, and human activities.

Front

How does competition affect populations?

Back

Competition occurs when individuals or species vie for the same resources (food, space, etc.), which can limit population growth and survival.

Front

What is predator-prey relationship?

Back

A predator-prey relationship is an interaction where one organism (the predator) hunts and consumes another organism (the prey), influencing population dynamics.

Front

Give an example of an abiotic limiting factor.

Back

An example of an abiotic limiting factor is a drought, which can limit water availability for plants and animals.

Front

Give an example of a biotic limiting factor.

Back

An example of a biotic limiting factor is the presence of predators, such as lions hunting elephants.

Front

What happens to a population when a density-dependent factor is removed?

Back

When a density-dependent factor is removed, the population may grow rapidly until it reaches the carrying capacity of the environment.
