  1. Ecology Notes

  2. What makes something alive? • It is made up of at least one cell • It uses homeostasis to maintain a balance in its body (temperature, heart beat/pressure) • It can adapt to its environment • It uses energy • It reproduces/grows

  3. Review of terms from field study What is the difference between a habitat and a niche? What is the difference between abiotic and biotic?

  4. Species • Similar organisms that can reproduce and make fertile offspring

  5. Population • A group of organisms of a single species together at the same time and place

  6. Community • Group of different species living together

  7. Ecosystem • All the biotic and abiotic things in an area

  8. Biosphere • Where all living things on Earth exist

  9. Food Chain • A diagram that shows one pathway of energy and who eats who. • The arrows represent which way the energy is flowing. • It always starts with a producer! • GrassAntBirdSnake • The grass is a producer because it produces its own food by using the sun’s energy. • Another word for producer is autotroph.

  10. GrassAntBirdSnake • The ant, bird and snake are called consumers because they have to consume other organisms for energy. • Another name for a consumer is a heterotroph. • Primary consumer-eats the producer (ant) • Secondary consumer-eats the primary consumer (bird) • Tertiary consumer- eats the secondary consumer (snake)

  11. Practice • 1. Who is the secondary consumer? How do you know? • 2. Who is the autotroph? How do you know? • 3. Name the heterotrophs in the food chain.

  12. Food Webs • More complex than a food chain and shows multiple pathways of energy

  13. Practice 1. Who are the primary consumers in the food web? 2. Who are the secondary consumers?

  14. Decomposers
