Lecture on Ecology

This lecture study of the interactions that take place among organisms and their environment. Ecosystem means all the organisms living in an area and the nonliving features of their environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), and number (population) of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Ecology is not synonymous with environment, environmentalism, natural history, or environmental science.
