General Ecology

ecology - ecology looks at the relationships between organisms and their environments.
interactions - interactions are communications or interplays between two or more organisms. Interactions do not need to be vocal. They can merely be the relationships that form between creatures. For instance, frogs interact with the environment of their pond. This means that they behave in a certain way to take advantage of the benefits the environment has to offer them.
distribution - this means the area and distance over which organisms can be found. abundance - this means the amount of organisms that can be found in a given area. For instance, if there is a lot of food in a certain area, the organisms will be more numerous (abundant).
