Learn how energy is transferred along a food chain.

Students will understand and describe food chains and food webs, and explain how energy is transferred between their trophic levels.

Read 37 slides on energy flow and the nutrient cycle.

Through a teacher-led discussion, students realize that the food energy plants obtain comes from sunlight via the plant process of photosynthesis. They learn what photosynthesis is, at an age-appropriate level of detail and vocabulary,...

College-level online course highlighting the fundamentals of ecology. Course topics include coevolution of the biosphere, geosphere, atmosphere, and hydrosphere; photosynthesis and respiration; and the carbon, nitrogen, and water cycles....

In this unit students explore major marine ecosystems by locating them on maps. Students use marine examples to learn about energy transfer through food chains and food webs and then they discuss how food webs can illustrate the health...

Explains the processes by which energy flows through an ecosystem. Covers the meanings of key vocabulary, e.g., types of producers and consumers, trophic levels, food webs, and the energy pyramid.

Complete illustrated discussion of energy flow within ecosystems, including discussions of trophic levels, ecological pyramids, food chains and webs, biological magnification, and cycles.

Try this five question comprehension check over ecosystems and the ecological relationships within them.

This website describes trophic levels, transfer of energy between trophic levels, pyramids of ecology, and nutrient cycles within the environment.

Review ecology, the study of how living organisms interact with each other and their surrounding environment.

This module offers an in depth study of the fundamental components of ecosystems. Activities include mini-lessons with videos and student assignments.
