Goal 4

The learner will investigate the cycling of matter.

Objective 4.01

Describe the flow of energy and matter in natural systems:

  • Energy flows through ecosystems in one direction, from the sun through producers to consumers to decomposers.
  • Matter is transferred from one organism to another and between organisms and their environments.
  • Water, nitrogen, carbon dioxide, and oxygen are substances cycled between the living and non-living environments.

Resources aligned to this objective

Biomagnification and bald eagles
In this activity, students will study biomagnification by using paper cutouts to represent food containing chemicals eaten by fish. The students will then repeat this activity but as an eagle collecting fish. The amount of chemicals taken in by each eagle will then be compared to amounts taken in by each fish.
