Grade 9 gradeScience subjectFree quiz

Grade 9 ecology scales from organism to biosphere: energy flow, nutrient cycles, population change, and community interactions. Students trace why available energy drops at higher trophic levels and how carbon and nitrogen move between living things and the environment. Human disruption of a cycle has system-wide effects.

What you practice

These are the Grade 9 Ecology & Ecosystems skills this quiz is built around.

Describe energy flow in a food web and why each trophic level stores less energy.
Outline a biogeochemical cycle such as carbon or nitrogen in basic steps.
Identify competition, predation, mutualism, or succession in a community example.

A useful tip

Energy in food webs is not recycled the way carbon atoms are. Heat loss at each transfer means far less chemical energy is available to top consumers than to producers.
