2. The study of interactions among organisms and between organisms and their environment.

3. Ecology: the study of how living organisms interact with each other and their nonliving environment

4. Ecology studies how all of these living and nonliving things interact

6. Ecosystem: all the organisms living in an area together with their physical environment Forest Ecosystem Pond Ecosystem Vacant Lot Ecosystem Desert Ecosystem

7. How does your ecosystem impact the Atlantic Ocean?

9. In order for an ecosystem to survive it needs five basic components: Energy Mineral Nutrients Water Oxygen Living Organisms

12. ECOSYSTEM

13. Biotic: living & once living parts of an ecosystem Plants, animals, bacteria, dead organisms, wastes Abiotic: nonliving parts of an ecosystem Air, water, soil, sunlight, temperature

14. What are some biotic AND abiotic parts of this ecosystem?

16. Organism: an individual living thing like you, a tree, a fox, a rose Species: groups of closely related organisms that can mate & produce fertile offspring like red foxes or black widow spiders, or grizzly bears

17. Species: groups of organisms that resemble each other in appearance, behavior, chemistry and genetic makeup…able to reproduce 3.6 to 100 million species (1.4 identified) Mostly insects/micro Tropical forests

18. Known species 1,412,000 Insects 751,000 Plants 248,400

19. Population: all the members of the same species that live in the same place at the same time Field mice living in a corn field, grizzly bears of Yellowstone Park Members breed with one another, rather than with other populations

21. Community: a group of various species that live in the same place and interact with each other Pond Community Pineland Forest Community

23. All parts of the Earth where life is found

24. Habitat: the place where an organism lives Organisms are well suited for their habitat

25. Habitats provide an organism with resources— anything an organism needs to survive and reproduce, including food, shelter, and mates

26. Influenced by temperature and precipitation

27. Weather – current condition of the atmosphere Climate – the general weather conditions prevailing in an area over a long period
