Title: Groups of living things interact within ecosystems.


1
Groups of living things interact within
ecosystems.
  • Chapter 2
  • Section 1

2
Organisms occupy specific living areas.
  • Species A group of living things that are so
    closely related that they can breed with one
    another and produce offspring that can breed as
    well

3
Organisms occupy specific living areas.
  • Population A group of organisms of the same
    species that live in the same area. For example,
    a desert will have populations of different
    species of lizards and cactus plants.

4
Organisms occupy specific living areas.
Members of the same species form a
population with in a habitat.
5
Organisms occupy specific living areas.
  • Habitats The natural environment in which a
    living thing gets all that it needs to live
    examples include a desert, a coral reef, and a
    freshwater lake.

6
Organisms occupy specific living areas.
  • Niche The role a living thing plays in its
    habitat. A plant is a food producer, whereas an
    insect both consumes food as well as provides
    food for other consumers.

7
Organisms occupy specific living areas.
Each species has a distinct role with in a
habitat. This is its niche.
8
Organisms occupy specific living areas.
  • Communities All the populations that live and
    interact with each other in a particular place.
    The community can live in a place as small as a
    pond or park, or it can live in a place as large
    as a rain forest or the ocean.

9
The environment can be organized into five levels.
  • 1. Biome In general terms describes the climate
    and types of plants that are found in similar
    places around the world
  • 2. Ecosystem Within each biome are many
    ecosystems where living and non-living factors
    interact to form a stable system

10
The environment can be organized into five levels.
  • 3. Community made up of the living components
    of the ecosystem, plants, animals, and other
    organisms interact
  • 4. Population A group of organisms of the same
    species that live in the same area
  • 5. Organism A single individual animal, plant,
    fungus, or other living things
