Niche Partitioning

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.

Competition between species can lead to competitive exclusion. What do you think competitive exclusion means?

• Competitive exclusion refers to the coexistence of multiple species in a given habitat.

• Competitive exclusion only occurs between species that are closely related.

• Two species competing for the same resources can coexist indefinitely.

• Two species competing for the same resources cannot coexist indefinitely.

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.

How does competition affect species diversity?

• It increases species diversity.

• It promotes species diversity.

• It has no effect on species diversity.

• It reduces species diversity.

What are some strategies used by species to avoid competition?

• Mutualism and symbiosis.

• Predation and parasitism.

• Territoriality and aggression.

• Niche partitioning

What is biodiversity?

• The number of individuals of a species in an area.

• The genetic variation within a species.
• The number of individuals in a particular habitat or on Earth as a whole.
• The variety of life forms in a particular habitat or on Earth as a whole.

What term do we use to define how an organism makes a living or fits into their community?

• niche

• carrying capacity

• predator-prey relationship
• habitat

True or False: Two species can coexist on the same limiting resource if they use it in the same way and at the same time.

• True
• False

Why is niche partitioning important for promoting biodiversity?

• Niche partitioning increases competition and reduces coexistence of different species.
• Niche partitioning reduces competition and promotes coexistence of different species.
• Niche partitioning has no effect on biodiversity.
• Niche partitioning only benefits a single species and not the overall ecosystem.
