Understanding the Biosphere: The Foundation of Life on Earth

The biosphere, the thin layer of Earth that supports life, is akin to the skin of an apple if the planet were scaled down to that size. This delicate layer maintains homeostasis, ensuring that organisms thrive. A population consists of interacting, interbreeding organisms of the same species, while a community encompasses all biotic factors within a specific area. An ecosystem integrates these communities with their abiotic environments, creating a complex web of interactions that sustain life. Explore the fundamental concepts of ecology and their implications for understanding our planet.

  1. Ecology is . . . http://www.phschool.com/science/ca_sci_exp_transparencies/earth_sci_unit5.pdf

  2. TheBiosphere the thin layer of the earth that supports life. • If the earth was the size of an apple, the biosphere would be the thickness of its skin.

  3. Yuh know me; I keep it homeostatic. • An organismhas all the characteristics of life.

  4. Hey Marty, tell those two to keep their interaction PG. • A population is group of interacting and interbreeding organisms. • Members of a population must be all the same species.

  5. A community is a group of interacting populations. Is he trying to tell me something?

  6. A community includes all the living things (biotic factors) in one place. • It contains no abiotic factors.

  7. Biotic Factor • An ecosystem is a community plus its non-living (abiotic) environment. Abiotic Factor
