Ecological Nich and Ecological Equivalence Quiz

What is habitat specialization and how does it contribute to ecological niche?

• It causes a species to have a broad ecological niche within its habitat, increasing competition with other species.

• It has no impact on a species' ecological niche within its habitat.

• It leads to a species being unable to occupy any ecological niche within its habitat.

• It allows a species to occupy a unique ecological niche within its habitat, reducing competition with other species.

Explain the concept of niche partitioning and provide an example of resource partitioning in an ecosystem.

• An example of resource partitioning is when all species in an ecosystem have the same diet and feeding habits

• The concept of niche partitioning is about animals fighting for the same resources in an ecosystem

• An example of resource partitioning in an ecosystem is the different beak sizes of Darwin's finches on the Galapagos Islands. Each species has evolved to have a beak size and shape that allows them to efficiently feed on different types of seeds, reducing competition for food resources.

• Resource partitioning in an ecosystem is when different species share the same food source without any competition

How does resource partitioning help in reducing competition among species in an ecosystem?

• By forcing species to compete for the same resources, leading to a decrease in overall biodiversity

• By creating a homogeneous environment where all species have equal access to resources

• By increasing the competition for resources among different species, leading to a decrease in population size

• By allowing different species to use different resources within the same ecosystem, reducing direct competition for the same resources.

State the competitive exclusion principle and its significance in ecological communities.

• Two species competing for the same resources can coexist peacefully

• Ecological factors have no impact on the coexistence of competing species

• The competitive exclusion principle only applies to plants, not animals

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

Describe the concept of ecological equivalence and its role in maintaining biodiversity in an ecosystem.

• Ecological equivalence is the similarity in the roles and functions of different species within an ecosystem, which helps maintain biodiversity by ensuring that if one species declines or disappears, another species can fulfill the same ecological role.

• Ecological equivalence is the concept of having only one dominant species in an ecosystem, which helps maintain biodiversity.

• Ecological equivalence is the competition between different species within an ecosystem, which leads to a decrease in biodiversity.

• Ecological equivalence is the process of introducing non-native species to an ecosystem, which helps maintain biodiversity.

What are the factors that contribute to the ecological equivalence of different species in an ecosystem?

• Different resource requirements, different environmental tolerances, and different effects on ecosystem processes

• Different resource requirements, similar environmental tolerances, and different effects on ecosystem processes

• Similar resource requirements, similar environmental tolerances, and similar effects on ecosystem processes

• Similar resource requirements, different environmental tolerances, and different effects on ecosystem processes

Explain the role of competitive exclusion principle in shaping the structure of ecological communities.

• The competitive exclusion principle has no impact on the structure of ecological communities.

• The competitive exclusion principle limits the number of species that can coexist in a community by preventing species with similar ecological niches from occupying the same space.

• The competitive exclusion principle encourages the coexistence of multiple species in a community by promoting competition.

• The competitive exclusion principle only applies to species with different ecological niches.

How does ecological equivalence contribute to the stability of an ecosystem?

• By reducing the number of species in the ecosystem

• By introducing new species to the ecosystem

• By ensuring that different species can perform similar roles, which reduces the impact of disturbances on the ecosystem.

• By increasing competition among different species
