  1. Ecology & Conservation A guide to Chapter 26

  2. Living Things and Their Environment • Environment: All living and nonliving things with which an organism may interact. • All of the living and nonliving things in an environment are interconnected.

  3. Ecosystems • Ecosystems: All the living and nonliving things in a given area that interact with one another

  4. Community • The living part of the ecosystem.

  5. Population • A group of organisms of the same type, or species, living together in the same area.

  6. Habitats • The place where an organism lives. It should provide food, shelter and all other resources an organism needs to survive.

  7. Energy Roles • Producers • Consumers • Decomposers

  8. Producers • The source of all the food in an ecosystem. Any organism that goes through photosynthesis.

  9. Consumers • An organism that feeds directly or indirectly on producers.

  10. Decomposers • Break down dead organisms into simpler substances.

  11. Food Chains • A series of events in which food and energy are transferred from one organism in an ecosystem to another. The first link is always a producer.

  12. Food Web • Many overlapping Food Chains

  13. Competition • When there are not enough resources to go around, organisms must struggle with one another to get what they need to survive.

  14. Predation • When one organism hunts another. • Predator: The organisms that hunt. • Prey: The organism that is eaten by the predator.

  15. Predation • When one organism hunts another. • Predator: The organisms that hunt. • Prey: The organism that is eaten by the predator.

  16. Symbiosis • A close relationship between two organisms in which one organism lives near, on or inside of another organism. One will benefit.

  17. Types of Symbiosis • Commensalism • Mutualism • Parasitism

  18. Adaptation • A change that increases an organism’s chance of survival. • Types: • Adapting to predators • Adapting to competition. • Adapting to symbiosis

  19. Ecology Games • Oh Deer!: Habitat, limiting factors, competition, population • Quick Frozen Critters: Predator, prey, adaptations, limiting factors,competition, population. • Muskox Maneuvers: Adaptations, predator, prey, limiting factors, populations • Deadly Links: food chains, pesticides.
