INTRO TO ECOLOGY

This introductory guide to ecology defines the study as exploring the interrelationships between animals, plants, and their environment. Delve into the levels of ecological organization, from the biosphere to individual organisms, and grasp concepts like niches, habitats, and the impacts of limited resources and competition. Gain insights into how organisms respond to biotic and abiotic factors, the importance of acclimation and adaptation, and the distinctions between generalist and specialist species. Discover the intricate web of life and the significance of maintaining balance in ecosystems.

Presentation Transcript

  1. INTRO TO ECOLOGY pp. 359-365

  2. Ecology Defined • Ecology means "study of homes" • study the relationships of animals, plants, and their environment (interdependence) • A small change can affect the whole ecosystem

  3. Levels of Organization

  4. Biosphere Earth and its atmosphere that supports life Ecosystem/Biome (kelp forest) The community and its physical aspects (pH, temp) Community (urchins, kelp, otters, sunflower star, etc) all organisms Population (all the sea urchins) members of one species in one place Organism (one sea urchin)

  5. Ecology of Organisms • Response to biotic (living) and abiotic (nonliving) factors

  6. conformers vs regulators • acclimation: adjust tolerance

  7. dormancy vs migration

  8. Niche/Habitat • Limited resources can result in competition

  9. Niche - the job of an organism (usually based on what they eat) 1. Generalist: broad niche 2. Specialist: narrow niche and more at risk from habitat destruction than generalists

  10. Habitat 1. The geographic location Organisms having the same niche or overlapping habitats can result in competition
