Niche Partitioning

How does niche partitioning contribute to the overall stability of an ecosystem?

• Niche partitioning only benefits a few species, leading to instability in the ecosystem.

• Niche partitioning reduces competition and allows for coexistence, leading to overall stability in the ecosystem.

• Niche partitioning increases competition and disrupts coexistence, leading to instability in the ecosystem.

• Niche partitioning has no effect on competition or coexistence in the ecosystem.

Answer explanation

Niche partitioning reduces competition, allowing coexistence and promoting stability in the ecosystem.

The ecological niches of three bird species are shown in the diagram. What is the advantage of each bird species having a different niche?

• As more birds feed higher in the tree, available energy increases.

• More abiotic resources are available for each bird.

• Predators are less likely to feed on birds in a variety of locations.

• There is less competition for food.

What is niche partitioning?

• The process of combining resources to increase competition among species.

• The sharing of unlimited resources among different species to promote competition.

• The elimination of resources to reduce competition and allow coexistence.

• The division of limited resources among different species to reduce competition and allow coexistence.

How does niche partitioning help in reducing competition?

• By increasing the overall population size of competing species.

• By promoting cooperation and sharing of resources among different species.

• By allowing different species to specialize in different food sources or habitats, reducing direct competition for resources.

• By creating barriers that prevent different species from interacting with each other.

What happens when two species have overlapping niches?

• The two species will learn how to cooperate with each other.

• Increase in population size for both species.

• Competition for resources and potential decrease in population size or loss of one species in that ecosystem.

• There is no effect or impact on the population size or survival of either species.
