Unit 5 Review: Predator/Prey Relationships

What is intraspecific competition?

• A relationship between predator and prey

• Competition between individuals of the same species for limited resources

• Interaction between two different species in an ecosystem

• A form of predation where herbivores consume plants

How does interspecific competition affect ecosystems?

• It leads to an increase in biodiversity

• It causes one species to always become extinct

• It can change population sizes and species distribution

• It has no effect on ecosystems

What role do parasitoids play in ecosystems?

• They are primary producers

• They help control pest populations

• They are a type of prey

• They compete with herbivores for plants

How does grazing affect plant communities?

• It allows a single plant species to dominate

• It helps maintain diverse ecosystems

• It eliminates all plant life

• It has no impact on plant communities

What is the main difference between intraspecific and interspecific competition?

• Intraspecific involves different species; interspecific involves the same species

• Intraspecific involves the same species; interspecific involves different species

• Intraspecific competition is always beneficial; interspecific is not

• Intraspecific competition occurs only in aquatic environments

What is a common consequence of predation in ecosystems?

• Increase in prey population

• Overpopulation of predators

• Regulation of prey populations

• Extinction of all predators

How can interspecific competition influence natural selection?

• It does not influence natural selection

• It leads to cooperation among all species

• It can drive adaptation and evolutionary change

• It eliminates the need for adaptation
