Document Summary
Biodiversity variability among living organisms from all sources including diversity between and among species and ecosystems. Ecology- the scientific study of the interactions between organisms and their environment. There is a balancer of nature in which natural systems are stable and tend to return to an original state following a disturbance. Each species has a distinct role to play in maintaining that balance. View that has stood the test of time: Events in nature are interconnected, and most species interact indirectly through resources. Energy moves through ecosystems in a single direction it is unable to be recycled. Population: a group of individuals of the same species. Community: multiple populations of different species living in the same geographical area. Ecosystem: a biological community of interacting organisms and their physical environment. Ecologists evaluate competing hypotheses about natural systems with experiments, observations and quantitative models. Controls are used to account for anything that may affect the result.
