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 chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems, such as sunlight, temperature, and mudslides.

Front

What are biotic factors?

Back

Biotic factors are living components of an ecosystem that affect the population of organisms, including predators, prey, and competition.

Front

Define density-dependent factors.

Back

Density-dependent factors are biotic factors that have a greater effect on a population as its density increases, such as competition, predation, and disease.

Front

Define density-independent factors.

Back

Density-independent factors are abiotic factors that affect populations regardless of their density, such as natural disasters, climate, and human activities.

Front

What is an example of a density-dependent factor?

Back

A disease spreading in densely populated areas is an example of a density-dependent factor.

Front

What is an example of a density-independent factor?

Back

A flood affecting an entire ecosystem is an example of a density-independent factor.

Front

What is competition in an ecological context?

Back

Competition occurs when two or more organisms vie for the same resource, such as food, space, or mates, which can limit their growth and survival.

Front

What is predation?

Back

Predation is an interaction where one organism (the predator) kills and eats another organism (the prey), affecting the population dynamics of both species.

Front

What is the predator-prey relationship?

Back

The predator-prey relationship is a biological interaction where the population of predators and prey influence each other's population dynamics.
