Curious about modes of nutrition? Join the Amoeba Sisters in learning about autotrophs and heterotrophs. Video explains these terms as well as how their carbon source differs. Photoautotrophs, photoheterotrophs, chemoautotrophs, and...

Hank brings us to the next level of ecological study with ecosystem ecology, which looks at how energy, nutrients, and materials are getting shuffled around within an ecosystem (a collection of living and nonliving things interacting in...

In this video Paul Andersen explains how ecosystems function. He begins with a description of how life on the planet is ordered from large to small in biomes, ecosystems, communities, population, and individuals. He describes the major...

“Woodland Habitat” introduces some of the animals that live in forests and discusses how they thrive in woodland environments.

Pupil outcome: I can create and interpret pyramids of number to show the size of a population at each trophic level. Key learning points: - Food chains show the feeding relationships between organisms and the flow of energy through a...
