Difficulty Level: At Grade Created by: CK-12
Turn In

Begin by discussing the main question posed at the beginning of the section, “What are the things you, or any organisms, need to survive?” Ask students to brainstorm a list of all the things they need for survival.

Use the list generated by students to illustrate the importance of basic resources such as water, food, and space.

Ask students to compare what they need to stay alive with an organism of their choice or the resources needed by a loon.

Assign What Do You Think?. Students will compare in writing their use of resources with the resources used by a teenager from another country.

Assign Activity 7-1: Too Many Bobcats to illustrate what happens when the number of bobcats exceeds the available resources in a habitat.

Emphasize the difference between a habitat and a niche.

Think about the resources you use in a typical day. If you had to give up three resources, what would you give up? How difficult would it be to do this? Compare your resource use to a loon's. How difficult would it be for a loon to give up three of its resources?

A suggested response will be provided upon request. Please send an email to teachers-requests@ck12.org.

How do the three main categories of resources differ for plants and animals?

What Do You Think?

How do you think the resources you use differ from those used by a teenager living in Bangladesh? Budapest? Which is a better use of the resources?
