What is Ecology?
  • Ecology is the study of interactions between

    (nonliving) components of the biosphere

    understand and resolve environmental and
    ecological issues

Web of Interdependence
  • Ecologists recognize two ecological truths
  • Our planet is home to not only humans but also
    many other life forms.
  • The health of human society depends on the
    well-being of all living things.
  • Life is interdependent because we all rely on
    each other for energy and nutrients.
