Rock Eaters of the Gulf of Alaska

Photosynthesis was discovered in the 1770s, but chemosynthesis wasn't discovered until 1977. While many have performed an experiment to show how photosynthesis works, the activity allows pupils to observe chemosynthesis. Scholars set up...

When a minnow eats a piece of plastic, that garbage often tracks through multiple animals, causing harm to each as it passes through the food chain. Scholars learn about food chains, food webs, and energy pyramids with a presentation. It...

View how autotrophs and heterotrophs use the energy of the sun to form the energy their cells need, ATP. Learners watch an informative video that details the processes of photosynthesis, learning where it occurs, what...

Young scholars are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At...

Discussion of the conversion of light energy to chemical energy through the life-sustaining process of photosynthesis. Explores the reactions of photosynthesis, where they take place, and their ecological importance.

Compare and contrast the energy generating processes of chemosynthesis and photosynthesis with this interactive resource.

Every living thing requires a food source, thus the interconnections in ecosystems become complex. Scholars learn about these interconnections in a presentation on energy flow. It starts with the sun and moves through many different...

In this cell energy learning exercise, learners will match 8 terms with their definitions relating to the biological processes that create energy in a cell. Then students will match 6 terms as being a part of photosynthesis, aerobic...

Explains how energy flows in ecosystems. Energy enters via producers through photosynthesis or chemosynthesis. Producers and consumers release the energy from food through cellular respiration. An explanation of gross primary...

Deep under the ocean there is no light for plants to perform photosynthesis. This site is a good overview of the alternative energy method, chemosynthesis. Read all about it.
