  1. TOPIC: EcologyAIM: What is Ecology?

  2. TOPIC: Ecology AIM: How do living things interact with their environment? DO NOW: What makes up the community you live in?

  3. Ecology Study of interactions that occur among organisms and their Physical Environment

  4. Ecosystem All living & nonliving things in environment Biotic factors = living Abiotic = nonliving

  5. Community All living things in an area Example: Pond: fish, frogs, plants…

  6. Population Living things of same species in community Example: Pond: all algae

  7. Habitat Where organism lives Salamanders live on the forest floor under leaves & twigs.

  8. Niche Role of an organism

  9. What it eats, • How it gets food & shelter,’ • How it finds a mate, cares for young…

  10. Limiting factors Anything that restricts the number of individuals in a population

  11. Food, light, other living things

  12. When does competition occur? When organisms seek same resource at same time

  13. When occupy the same niche

  14. Types of Organisms

  15. Producers Autotrophs Plants

  16. carbon dioxide from the air water from the roots energy from sunlight (or light) food transported to the rest of the plant

  17. Consumers Heterotrophs

  18. Types: • 1. Herbivores = • feed on producers • primary consumers

  19. 2. Carnivores = • feed on animals (meat eating) • Secondary consumer

  20. 3. Omnivores = • Eat plants & animals

  21. 4. Scavengers = • feed on animals killed by other organisms. Ex-vultures • (vultures)

  22. 5. Predators = • Kills prey & feeds on them

  23. Decomposers Break down remains of dead organisms return nutrients into soil (bacteria and fungi)

  24. REVIEW What is an ecosystem? Explain the difference between a community and a population? What type of organism is an autotroph? How is a decomposer beneficial to an ecosystem? Explain the differences between carnivores, herbivores, and omnivores.
