Environmental Science Realized vs. Fundamental Niche

What is resource partitioning?

• Resource partitioning is the process where different species use the same part of a resource to compete.

• Resource partitioning is the process where different species avoid using the same resource.

• Resource partitioning is the process where different species use the same resource at the same time.

• Resource partitioning is the process where different species use different parts of the same resource to avoid competition.

Explain the concept of competitive exclusion.

• Competitive exclusion only occurs when ecological factors change

• Competitive exclusion is not related to resource competition

• Two species competing for the same resources cannot coexist if other ecological factors remain constant.

• Two species competing for the same resources can easily coexist

Differentiate between realized niche and fundamental niche.

• Realized niche is the entire range of environmental conditions that a species can potentially occupy, while fundamental niche is the actual space and resources a species uses.

• Realized niche is the space and resources a species uses, while fundamental niche is the entire range of environmental conditions that a species can potentially occupy.

• Realized niche is the actual space and resources a species uses, while fundamental niche is the entire range of environmental conditions that a species can potentially occupy.

• Realized niche is the entire range of environmental conditions that a species can potentially occupy, while fundamental niche is the actual space and resources a species uses.

Provide an example of resource partitioning in an ecosystem.

• Different species of fish living in the same part of a river

• Various types of plants competing for sunlight in a forest

• Multiple species of insects sharing the same food source

• Different species of birds feeding on different levels of a tree

How does competitive exclusion affect the population of species in an ecosystem?

• It leads to the decline or extinction of the less competitive species.

• It leads to the decline or extinction of the more competitive species

• It has no impact on the population of species

• It increases the population of less competitive species

Discuss the factors that can limit the fundamental niche of a species.

• Habitat destruction, overpopulation, and disease

• Competition, predation, resource availability, and abiotic factors

• Climate change, genetic mutation, and symbiosis

• Migration, pollution, and random chance

Explain the relationship between ecological niches and the exclusion principle.

• Two species can occupy the same niche in the same habitat

• The ecological niche determines the resources a species needs, while the exclusion principle explains why two species cannot occupy the same niche in the same habitat.

• The exclusion principle determines the resources a species needs

• The ecological niche has no impact on the exclusion principle

Describe the impact of resource partitioning on the biodiversity of an ecosystem.

• Resource partitioning increases the biodiversity of an ecosystem by allowing different species to coexist and utilize different resources.

• Resource partitioning only benefits one species in an ecosystem, leading to a decrease in biodiversity.

• Resource partitioning decreases the biodiversity of an ecosystem by limiting the resources available to different species.

• Resource partitioning has no impact on the biodiversity of an ecosystem.

Discuss the significance of understanding ecological niches and the exclusion principle in conservation biology.

• Competition and resource partitioning have no impact on species coexistence in conservation biology

• Conservation biology does not rely on understanding species interactions and roles within an ecosystem

• Understanding ecological niches and the exclusion principle is crucial in conservation biology as it helps in identifying and protecting the unique roles and interactions of species within an ecosystem, and in understanding how competition and resource partitioning affect species coexistence.

• Understanding ecological niches and the exclusion principle is not important in conservation biology

What is an ecological niche?

• A niche is defined where an organism in its environment, competes for the resources and interactions including the biotic and abiotic factors of the environment.

• A niche is defined as the position that an organism has in its environment, excluding all the interactions with the abiotic factors of the environment.

• A niche is defined as the role or position that an organism has in its environment, including all the interactions with the biotic and abiotic factors of the environment.

• A niche is defined as the position that an organism has in its environment, excluding all the interactions with the biotic factors of the environment.
