  1. POPULATIONS & ECOSYSTEM

  2. BIOSPHERE • The thin upper part of earth’s surface and its atmosphere is capable of supporting life.

  3. HABITAT • A place where a plant or animal lives that provides the 4 basic needs. • Animal life is closely linked to plant life

  4. Size of habitat depends on the organism

  5. Environment • The conditions around an organism and how the organism changes and reacts to these conditions. • Is affected by the climate, water, and soil as well as how the plants and animals react to each other

  6. Ecosystem • Area where living things interact with each other and their environment. Environments can be large as wetlands, Deserts, tundra, or small as a pond, puddle, rotting log

  7. BIOTIC FACTORS • The living parts of an ecosystem. Ex. Animals, plants

  8. Abiotic Factors • The non-living parts of an ecosystem. • Ex. Weather and sunlight

  9. ECOLOGY • The study of how living things interact within a community

  10. ADAPTATION • A character or structure that helps an organism live and reproduce successfully in its environment overtime. • http://interdependence.londongt.org/adaptation/index.php?chapter=starter&activity=venusFlytrap&editorialItem=instructions&teacher=false&fullScreen=false

  11. BIOME • Natural regions with similar climates and vegetation that provides similar habitats. • There are many small communities in each biome

  12. COMMUNITY • Two or more groups of different organisms living together and interacting with each other in the same area.

  13. Niche • The specific role an organism has in it’s habitat. • Includes all the activities and behaviors that satisfy an organisms need for food, water, living, space and reproduction

  14. FOOD CHAIN • A group of organisms linked together in the order of which they feed on each other. • Ex. Sun -> grass-> chicken -> eggs -> You

  15. Grass is eaten by Grasshopper is eaten by Toad is eaten by Snake And snake is eaten by Hawk

  16. FOOD WEB • Is when food chains in a community link together.

  17. PRIMARY SOURCE • The sun is the primary source of energy

  18. Plants • Uses the sun’s energy to make (produce) their own food by photosynthesis. • Called “Producers” they are the only organisms in the chain that can use nonliving matter to produce (make) food.

  19. ANIMALS • Are not able to produce their own food, they must eat other organisms • Called “consumers” • Consumer means they have to eat organisms that make their own food (plants) • Broken into groups based on what they eat
