Intraspecific Competition and Interspecific Competition

Create a 12- to 15-slide Microsoft® PowerPoint® presentation that includes the following:

An overview of intraspecific competition and interspecific competition; explain these terms, and provide a brief overview of each.
How does intraspecific competition and interspecific competition affect populations?
Review the intraspecific competition data in the University of Phoenix Material: Intraspecific Competition.
How is the predator community affected by low numbers of prey?
How do high numbers of predators affect the prey community?
What are some possible effects on other species?
Review the interspecific competition data in the University of Phoenix Material: Interspecific Competition.
What behavioral data might be inferred from this graph?
What factors might be responsible for the success of the older mothers’ offspring?
Propose a scenario that might explain the data recorded. How might interspecific competition affect the reproductive success?
How does intraspecific competition and interspecific competition drive natural selection and evolution?
Include data in the graphs to support your answers.University of Phoenix Material
