This handout is perfect for an introduction or enrichment to the keystone species and ecosystems, a great sub-plan, enrichment, or lesson all in its own right. The question EDITABLE handout available in word document and pdf include 15 short answer questions that are timed in sequence to the video, and 5 summarizing analysis questions.

The questions are formatted short-answer style, however no answer is much longer than words. The questions are spaced out so that they do not go too fast or too slow and encompass the entire film from start to finish. This short film tells the story of how these concepts were first established through the pioneering experiments of two young researches: Robert Paine and James Estes.

Or how many individuals of the species can live somewhere? James Estes and colleague John Palmisano discovered that the kelp forest ecosystems of the North Pacific are regulated by the presence or absence of sea otters, which feed on sea urchins that consume kelp.

These direct and indirect effects of sea otters on other species describe a trophic cascade. These early studies were the inspiration for hundreds of investigations on other keystone species and trophic cascades, as well as ongoing studies into the regulation of population sizes and species numbers.

One way to understand how animal species interact in an ecosystem is to determine what eats what. Researchers create food chains and food webs to understand populations at different trophic levels and determine the health and stability of the ecosystem as a whole. Human-caused and natural disturbances can disrupt these interactions and reduce stability. In this lesson, you will learn about how food webs are constructed and trophic levels in an ecological community.

You will then use animals that you identify in WildCam Gorongosa to construct food chains and food webs, and then study the impacts of disturbances. Skip to main content. Lesson 4 - Gorongosa's Food Webs. Resource Type.
