Document Summary
Ecology is the study of how organisms interact with their environment. If the factors that affect population size can be described accurately enough, mathematical models can assess the impact of proposed dams, changes in weather patterns, altered harvest levels or specific types of protection efforts. 2: biologists might also analyze how groups of species respond to disturbances such as fires, floods and volcanic eruptions, ex. In both habitats, they are subject to parasitism and disease. Salmon form a link between marine and freshwater ecosystems: they harvest nutrients in the ocean and when they die and decompose, they transport these molecules to streams. In this way, salmon transport chemical energy and nutrients from one habitat to another. Conservation biology is the effort to study, preserve and restore threatened populations, communities and ecosystems. Ecologists study how interactions between organisms and their environments result in a particular species being found in a particular area at a particular population size.
