    1. Ecology

    2. The study of the interactions that take place among organisms and their environment

    3. Biosphere The part of Earth that supports life Top portion of Earth's crust All the waters that cover Earth's surface Atmosphere that surrounds Earth.

    5. Ecosystem All the organisms living in an area and the nonliving features of their environment

    7. Population All the organisms in an ecosystem that belong to the same species

    9. Community All the populations in an ecosystem

    11. Habitat The place in which an organism lives provides the kinds of food and shelter, the temperature, and the amount of moisture the organism needs to survive

    13. Competition Food Space

    14. Competition Competition caused by population growth affects many organisms, including humans Limits population size

    16. Limiting Factor Anything that restricts the number of individuals in a population. Includes living and nonliving features of the ecosystem

    18. Succession Natural, gradual changes in the types of species that live in an area; can be primary or secondary. Primary begins in a place without soil Secondary where soil already exists

    21. Primary Succession

    22. Secondary Succession

    23. Pioneer species A group of organisms, such as lichens, found in the primary stage of succession and that begin an area's soil-building process

    25. Climax community A community that has reached a stable stage of ecological succession

    27. Biome Large geographic areas with similar climates and ecosystems

    29. Includes Tundra Taiga Desert Temperate deciduous forest Temperate rain forest Tropical rain forest, and grassland
