Describe the basic interactions and relationships among living things.
Ecology teaches that everything is connected to everything else.
It is the study of the interactions of organisms with one another and with their physical surroundings. Students will learn about these interactions or interconnections beginning with the concepts of environment and ecosystem. It includes the structure of ecosystems and the roles of organisms in populations and communities. Students will learn that a population is a group of organisms that all belong to the same species and live in a given area. A community consists of all the various populations of organisms living in a given area.
