  1. What is Ecology? 1

  2. Organisms and Their Environment 2

  3. What is Ecology?? 3 • The study of interactions that take place between organisms and their environment. • It explains how living organisms affect each other and the world they live in.

  4. Habitat & Niche 4 • Habitat is the place a plant or animal lives • Niche is an organism’s total way of life

  5. The Nonliving Environment 5 • Abiotic factors- the nonliving parts of an organism’s environment. • Examples include air currents, temperature, moisture, light, and soil. • Abiotic factors affect an organism’s life.

  6. The Living Environment 6 • Biotic factors- all the living organisms that inhabit an environment. • All organisms depend on others directly or indirectly for food, shelter, reproduction, or protection.

  7. Abiotic or Biotic? 7 Biotic

  8. Abiotic or Biotic? 8 Abiotic

  9. Abiotic or Biotic? 9 Abiotic

  10. Abiotic or Biotic? 10 Biotic

  11. Levels of Organization 11

  12. What are the Simplest Levels? 12 • Atom • Molecule • Organelle • Cell • Tissue • Organ • System

  13. Levels of Organization 13 • Ecologists have organized the interactions an organism takes part in into different levels according to complexity.

  14. 1st Level of Organization 14 • Organism:An individual living thing that is made of cells, uses energy, reproduces, responds, grows, and develops

  15. 2nd Level of Organization 15 • Population:A group of organisms, all of the same species, which interbreed and live in the same place at the same time.

  16. 3rd Level of Organization 16 • Biological Community:All the populations of different species that live in the same place at the same time.

  17. 4th Level of Organization 17 • Ecosystem: Populations of plants and animals that interact with each other in a given area with the abiotic components of that area. (terrestrial or aquatic)

  18. 5th Level of Organization 18 • Biome:group of ecosystems with the same climate and similar dominant communities

  19. 6th Level of Organization 19 • Biosphere:The portion of Earth that supports life.

  20. The Biosphere 20 • Life is found in air, on land, and in fresh and salt water. • The BIOSPHERE is the portion of Earth that supports living things.

  21. 21 Does this make it easier to understand the complexity???

  22. What level of organization? 22 Organism

  23. What level of Organization? 23 Community

  24. What level of Organization? 24 Population

  25. Extension Work 25 • Create a foldable on the following Land Biomes: • Tropical Rain Forest • Tropical Savanna • Desert • Temperate Grassland • Temperate Woodland/ Shrubland • Coniferous Forest • Boreal Forest • Tundra

  26. Include the following information: 26 • Precipitation • Temperature • Soil • Diversity • Plants • Animals
