Ecology is the study of the interactions among plants and animals and the physical environment . Every population affects and is affected by other populations and by the physical environment in which they live. Conditions there control the survival and affect the success of all organisms. Nothing can exist by itself.
Ecological relationships are the ways that things in an environment interact with each other.
There is no way to study all the ecological relationships of the entire world, or even a single island, so we select small parts of the environment and specific relationships to study. The area we will study we will call the class study area. In this class study area, you will select a small patch of ground called a quadrat. Select this quadrat with vegetation, insect s nesting site, or something else that is likely to change within the school year. Using the small quadrat lets you observe and measure changes over a span of time.
