  1. 1. Ecology Module 2
  2. 2. Ecology <ul><li>The study of interactions between organisms and their environment </li></ul><ul><li>Those that study ecology are ecologists </li></ul>
  3. 3. Organization of Life
  4. 4. Organization of Life <ul><li>All living matter can be organized </li></ul><ul><ul><li>SMALLEST--> LARGEST. </li></ul></ul><ul><ul><li>Ecology deals with the levels </li></ul></ul><ul><ul><ul><li>Organisms </li></ul></ul></ul><ul><ul><ul><li>Populations </li></ul></ul></ul><ul><ul><ul><li>Communities </li></ul></ul></ul><ul><ul><ul><li>Ecosystems </li></ul></ul></ul><ul><ul><ul><li>Biomes </li></ul></ul></ul><ul><ul><ul><li>Biosphere </li></ul></ul></ul>
  5. 5. Organisms <ul><li>Ecologists may study the behavior on an individual organism . </li></ul><ul><ul><li>They may study its daily movements, feeding, or breeding behaviors. </li></ul></ul><ul><li>Ex </li></ul><ul><ul><li>A deer </li></ul></ul><ul><ul><li>A Shark </li></ul></ul>
  6. 6. Populations <ul><li>A group of organisms of one species that interbreed and live in the same place at the same time. </li></ul><ul><ul><li>Compete for food, water, mates, and other resources </li></ul></ul><ul><ul><li>Resources determine how big/small a population is </li></ul></ul><ul><li>They may also study growth rates of populations and predict future populations </li></ul><ul><li>Ex </li></ul><ul><ul><li>Many deer </li></ul></ul><ul><ul><li>Endangered species </li></ul></ul>
  7. 7. Communities <ul><li>A collection of interacting populations </li></ul><ul><ul><li>All organisms in a community depend in someway on the other organisms living there. </li></ul></ul><ul><ul><li>Ecologists are concerned with studying the effects on the community when a new species is added or removed. </li></ul></ul><ul><li>Ex </li></ul><ul><ul><li>Hawks go up then mice go down </li></ul></ul>
  8. 8. Ecosystem <ul><li>All the biotic and abiotic factors in an area from an ecosystem . </li></ul><ul><ul><li>Ecologists are concerned with ecosystem stability and knowing what keeps ecosystems stable. </li></ul></ul><ul><ul><li>Ex </li></ul></ul><ul><ul><ul><li>Rain forest </li></ul></ul></ul>
  9. 9. Biome <ul><li>A group of ecosystems that together make up a specific region for species to live </li></ul><ul><li>Similar climate </li></ul><ul><ul><li>Temperature </li></ul></ul><ul><ul><li>Elevation </li></ul></ul><ul><ul><li>Rainfall </li></ul></ul>
  10. 10. Biosphere <ul><li>The biosphere is the highest level of organization. </li></ul><ul><li>It is made up of the entire planet and all its living and nonliving parts </li></ul><ul><li>Ecologists are concerned with all interactions within the biosphere. </li></ul>
  11. 11. Living environment= Biotic factors <ul><li>Living things are found in air, on land, in both fresh and salt water </li></ul><ul><li>The Biosphere is the portion of the Earth that supports life </li></ul><ul><li>Biotic factors= all living organisms </li></ul>
  12. 13. Nonliving factors= Abiotic Factors <ul><li>Environment </li></ul><ul><ul><li>Air currents </li></ul></ul><ul><ul><li>Temperature </li></ul></ul><ul><ul><li>Moisture </li></ul></ul><ul><ul><li>Light </li></ul></ul><ul><ul><li>Soil </li></ul></ul>
  13. 15. Where and how organisms live <ul><li>Every species has a particular function in its community </li></ul><ul><ul><li>A Niche is the role a species plays in a community </li></ul></ul><ul><ul><li>The space, food, and other conditions an organism needs to survive and reproduce are part of it’s niche </li></ul></ul><ul><ul><ul><li>Ex </li></ul></ul></ul><ul><ul><ul><ul><li>Fungi= break down of organic matter </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Coyotes= keep rodents down </li></ul></ul></ul></ul>
  14. 17. Habitat <ul><li>A place where organism lives out its life </li></ul><ul><ul><li>Ex bird in trees </li></ul></ul><ul><ul><li>Prairie dog in grassland burrows </li></ul></ul><ul><ul><li>Several species share habitats , the food, shelter and other resources of that habitat are divided into separate niches </li></ul></ul>
