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 happens to a predator population when its prey population decreases?

Back

The predator population typically decreases as well, due to a lack of food resources.

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 population size regardless of the population's density, such as natural disasters or climate.

Front

What is the predator-prey relationship?

Back

The predator-prey relationship is an interaction where one organism (the predator) hunts and consumes another organism (the prey), influencing their populations.

Front

How does overgrazing affect an ecosystem?

Back

Overgrazing can lead to food shortages for various species, disrupt the balance of the ecosystem, and cause habitat degradation.

Front

What is competition in an ecological context?

Back

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

Front

Give an example of a density-dependent limiting factor.

Back

An example of a density-dependent limiting factor is the spread of disease, which becomes more severe as population density increases.

Front

What is herbivory?

Back

Herbivory is the consumption of plant material by animals, which can limit plant populations and affect the structure of the ecosystem.

Front

What is the effect of a new predator introduced to an ecosystem?

Back

The introduction of a new predator can lead to a decline in prey populations, potentially causing a cascade of effects throughout the ecosystem.
