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....

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

A module that explains what an ecosystem is and how energy and matter move through them. Students will look at the different roles of plants and animals and at ecological relationships in food chains and food webs.

This lesson focuses on food chains in ecosystems, including levels of consumers, decomposers, and a list of common words used with food chains and their definitions. It also provides a link to an assessment.

This lesson focuses on the organization of an ecosystem. The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. It provides...

This unit shows how ecosystems change over time and how matter and energy, which are essential to its operation, are transformed and passed from one living thing to another forming, in some cases, authentic cycles. It contains 19...

Connect the dots to investigate three different habitats either the forest, bai or river of the rain forest. By connecting the dots students make a food chain to see how organisms in each habitat depend on each other.

Think and Link to investigate three different ecosystem either the deep sea, coral reef or continental shelf. By connecting the dots students make a food chain to see how organisms in each habitat depend on each other.

[Free Registration/Login may be required to access all resource tools.] Students will recognize and understand the role of producers in the food chain within different ecosystems.

Create the parameters of your own ecosystem by choosing which producers and consumers live there. Visualize how the food web operates and species populations change. This simulator mimics the food web within a typical ecosystem and gives...

A suite of lessons focusing on the process of upwelling. Inquiry-based exploration of seasonal upwelling includes marine food webs, food production in the ocean, wind-driven ocean currents, and seasonal changes in biotic and abiotic...

Students explore the biosphere's environments and ecosystems, learning along the way about the plants, animals, resources and natural cycles of our planet. Over the course of lessons 2-6, students use their growing understanding of...

Students learn about Abiotic and Biotic Factors and how they affect the ecosystem in which an animal might live in.

Fun, interactive game that helps students identify interrelationships in an ecosystem. For six or more players.

Students and teachers can explore the work of marine scientists and observe the ocean from their computers. Learn about Rutgers Coastal Ocean Observation Laboratory, discover why oceanography is important, and see what life is like in...
