By MICHAEL IP. Forty years ago, on March 29, 1973, the United States ended its military involvement in Vietnam. Although the war would continue another two years, the South Vietnamese would no longer receive American assistance.
Ecology (from Greek: Î¿á¼¶ÎºÎ¿Ï, house, or environment; -Î»Î¿Î³Î¯Î±, study of) is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography, and Earth science.
The first question is easy to answer: ecology is the study of interactions between organisms and their environments. Interactions is the key word here. Ecologists do not only study organisms; they also study how organisms interact with other organisms and how they interact with the nonliving parts of their environments, like chemicals, nutrients, habitats, and so on. As you might suspect, ecology is not as simple as it sounds.
