    living thing

    obtains food, water, shelter and other things it needs to live, grow and reproduce from its environment
  2. HABITAT
    An environment that provides that things the organisms need to live, grow, and reproduce
  3. BIOTIC FACTORS
    Living parts of a habitat

    Example: Animals, plants, bacteria, and fungi
  4. ABIOTIC FACTORS
    Nonliving parts of an organism's habitat
  5. 5 MAIN ABIOTIC FACTORS
    • 1. Water
    • 2. Sunlight
    • 3. Oxygen
    • 4. Temperature
    • 5. Soil
  6. PHOTOSYNTHESIS
    The process in which organisms use water along with sunlight and CO 2 to make their own food
  7. ORGANISM LEVELS OF ORGANIZATION
    Organism--Population--Community--Ecosystem

    (OPCE)
  8. SPECIES
    A group of organisms that are physically similar and can mate with each other and produce offspring that can also mate and reproduce
  9. POPULATION
    All the members of one species in a particular area
  10. COMMUNITY
    All the different populations that live together in an area
  11. ECOSYSTEM
    The community of organisms that live in a particular area, along with their nonliving surroundingsĀ 

    Example: Prairie, Desert, Mountain, and Puddle
  12. ECOLOGY AND ECOLOGIST
    The study of how living things react with each other and with their environment
  13. WHAT BASIC NEEDS ARE PROVIDED BY AN ORGANISM'S HABITAT?
    Food, water, shelter, and other things an organism needs to grow and reproduce
  14. WHAT MIGHT HAPPEN TO AN ORGANISM IF ITS HABITAT COULD NOT MEET ONE OF ITS NEEDS?
    The organism might die
  15. LIST ALL OF THE BIOTIC AND ABIOTIC FACTORS IN FIGURE 4
    Biotic- Grass, birds, snake, badger, bison, and prairie dog

    Abiotic- Soil, air, temperature, and sunlight
  16. EXPLAIN WHY WATER AND SUNLIGHT ARE TWO OF THE MOST IMPORTANT TO ALL ORGANISMS
    All organisms need water to carry on life processes. Plants and algae need sunlight to make food in photosynthesis. Other organisms depend directly or indirectly on the plants and algae for food.
  17. LIST ALL THE TERMS IN ORDER FROM THE SMALLEST LEVEL TO THE LARGEST: POPULATION, ORGANISM, ECOSYSTEM, AND COMMUNITY
    Organism--Population--Community--Ecosystem
  18. WOULD ALL OF THE DIFFERENT KINDS OF ORGANISMS IN A FOREST BE CONSIDERED A POPULATION OR AND COMMUNITY? EXPLAIN
    A community because a community consists of different populations living together
