Resource Partitioning and Competition Concepts

The video explores interactions among species in ecosystems, focusing on interspecific and intraspecific interactions. It explains predation, competition, and the competitive exclusion principle. The concept of resource partitioning is introduced, showing how species can coexist by utilizing different parts of a resource or being active at different times.

What is the term for interactions between different species, such as when one species preys on another?

• Intraspecific interactions

• Mutualistic interactions

• Interspecific interactions

• Symbiotic interactions

When two members of the same species compete for a resource, what type of interaction is this?

• Interspecific competition

• Intraspecific competition

• Symbiosis

• Predation

How does an increase in population density affect competition within a species?

• It eliminates competition

• It increases competition

• It has no effect on competition

• It decreases competition

What happens when one species is better at competing for resources than another?

• The less competitive species outcompetes the other

• Both species become equally common

• The more competitive species becomes more common

• The less competitive species becomes more common

What principle describes the scenario where one species completely outcompetes another in a shared niche?

• Resource partitioning

• Competitive exclusion principle

• Mutualism

• Commensalism

What is a possible outcome when two species compete for the same niche?

• Neither species is affected

• Both species are eliminated

• One species may be excluded

• Both species thrive equally

What is resource partitioning?

• When species compete for the same resource

• When species form a mutualistic relationship

• When one species eliminates another from a niche

• When species share resources by occupying different niches

Which of the following is an example of resource partitioning?

• A predator-prey relationship

• Two species of birds feeding at different times of the day

• Two species living in the same part of a tree

• Two species of fish competing for the same food

In the context of resource partitioning, what might different parts of a tree provide?

• No conditions suitable for any species

• Identical conditions for all species

• Different conditions suitable for different species

• The same conditions for all species

How can species coexist in the same ecosystem despite competition?

• By avoiding competition

• By eliminating each other

• By resource partitioning

• By occupying the same niche
