After examining the animals in the WildCam photos, one question you may have is how do these animals interact? 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.
