Limiting Factors & Competition

What are limiting factors? Write the limiting factor in each statement on your paper.

What are limiting factors? Write the limiting factor in each statement on your paper. Discuss in your groups. 1. Limited food will limit the polar bear population. Low temperatures in the Arctic restrict the growth of trees. 2. Cardinals must compete with each other for nesting spots in a tree. 3. A reduced mouse population causes many owls who feed on them to move to a new area.

Limiting factors play an important role in an ecosystem. What do you know about

Limiting factors play an important role in an ecosystem. What do you know about them? Label the following statements as true or false on your paper. You may discuss with the person next to you. Only abiotic factors of an environment can be limiting factors. Competition for a resource can make that resource a limiting factor. Possible limiting factors contain food, water, and living space. Limiting factors influence the sizes of populations but not the types of populations in an ecosystem.

Consider this ecosystem: This ecosystem has enough: Space, shelter, and water to support 20

Consider this ecosystem: This ecosystem has enough: Space, shelter, and water to support 20 rabbits. Food for 10 rabbits. There are 15 rabbits living there now.

Write the questions and answers on your paper. Discuss with your group. The limiting

Write the questions and answers on your paper. Discuss with your group. The limiting factor in the ecosystem is . Food The rabbit population size is _______. Share out what you know about the population size. Do the same limiting factors limit all species the same way?

We know the ecosystem has only enough food for 10 rabbits, but 15 rabbits

We know the ecosystem has only enough food for 10 rabbits, but 15 rabbits are living there now. Discuss in groups. 1. What caused food to be a limiting factor? 2. What likely happened to the rabbit population as a result?

Competitions often influences the sizes of populations in an ecosystem. What are some ways

Competitions often influences the sizes of populations in an ecosystem. What are some ways competition affects population size? Turn and Talk to shoulder partner or person across from you. Write some examples on your paper.

Write this down! An ecosystem in a park area contains hawks, which feed on

Write this down! An ecosystem in a park area contains hawks, which feed on mice. The mice eat the seeds of various plants. Why do populations of plants and mice become limiting factors in this ecosystem? Discuss in your groups and jot reasons on your paper.
