As top predators, they help to keep a balance in the food chain where they live, playing an important role in controlling the populations of other species and promoting healthy ecosystems. Purple Sea Stars were the first recognised keystone species. Ecosystem engineers modify their habitats through their own biology or by physically changing biotic and abiotic factors in the environment. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. What is the effect of any species in a food chain upon one another? A trophic cascade describes changes in an ecosystem due to the addition or removal of a predator. Beavers are an integral part of a wetlands ecosystem.

The environmental benefits of the bee are numerous. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat. Bees get a food resource by visiting flowers, and flowers get pollinated by bee activities. Describe what a metapopulation is and how this concept applies to the conservation of a species or invasive species dynamics. b. a. Commensalism b. After a short characterisation of wild bees, their role as key-stone species in communities and a discussion of the ecological consequences of the "pollination crises" for natural and man-made . The carcasses of their prey not only redistribute nutrients back into the soil but also provide food for scavengers and other animals. 2) Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
