  3. Organism Organism • An organism is an individual living thing(such as an alligator)

  4. Population Population Organism Organism • A population is a group of the same species that lives in one area.

  5. Community Community Population Population Organism Organism • A community is a group of different species that live together in one area.

  6. While the earth is huge, life is found in a very narrow layer, called the biosphere. If the earth could be shrunk to the size of an apple, the biosphere would be no thicker than the apple's skin.

  7. The biosphere, like the human body, is made up of systems that interact and are dependent on each other. The biosphere’s systems are called ECOSYSTEMS.

  8. Ecosystem Ecosystem Community Community Population Population Organism Organism • An ecosystem includes all of the organisms as well as the other nonliving things in a given area.(such as climate, soil, water, rocks)

  9. Biome Ecosystem Ecosystem Community Community Population Population Organism Organism • A biome is a major regional or global community of organismscharacterized by the climate conditions and plant communities that thrive there.

  10. Biome a major regional or global biotic community, a super ecosystem, defined chiefly by the dominant forms of plant life and the prevailing climate

  11. Major Biomes of the World desert grassland tropical rain forest deciduous forest coniferous forest tundra ocean

  12. biome ecosystem community population organism organ system organ tissue Levels of Organization smallest unit of living things large region with typical plants and animals that includes several ecosystems group of different kinds of tissues working together group of organs working together all living and nonliving things interacting within a certain area all organisms of the same kind living in one area all interacting populations in an ecosystem one individual living thing group of similar cells organized to work together cell

  13. Section 13.2 KEY CONCEPT: Every ecosystem includes both living and nonliving factors.

  14. Elements in an Ecosystem • Biotic factors are living things. • Remember, BIO means LIFE! (like Biology) • plants • animals • fungi • bacteria

  15. Examples of Biotic Factors include plants, animals, fungi, microorganisms

  16. Abiotic factors are nonliving things. • Remember, “A” means NOT (like Asymmetrical means not symmetrical) • sunlight • temperature • wind • Moisture • Water, rain, clouds • soil

  17. Examples of Abiotic Factors include air, water, soil, temperature, wind, source of energy (usually sun)

  18. Ecological Niche • A plant's or animal's ecological niche is a way of life that is unique to that species. • Niche and habitat are not the same. While many species may share a habitat, this is not true of a niche. Each plant and animal species is a member of a community. • The niche describes the species' role or function within this community.

  19. For example, the red fox's habitat, which might include forest edges, meadows and the bank of a river, is shared with many animals . • The niche of the red fox is that of a predator which feeds on the small mammals, amphibians, insects, and fruit found in this habitat. Red foxes are active at night. They provide blood for blackflies and mosquitoes, and are host to numerous diseases. The scraps, or carrion, left behind after a fox's meal provide food for many small scavengers and decomposers. This, then, is the ecological niche of the red fox. • Only the red fox occupies this niche in the meadow-forest edge communities. In other plant communities different species of animal may occupy a similar niche to that of the red fox.

  20. Keystone • Changing one factor in an ecosystem can affect many other factors. • A keystone species is a species that has an unusually large effect on its ecosystem. If you moved this stone the whole arch would fall down

  21. creation of wetland ecosystem increased waterfowl Population keystone species increased fish population nesting sites for birds • Keystone species form and maintain a complex web of life.

  22. Chapter 13-1 & 13-2 Review questions • What is Ecology? • Define organism, population, community, biome, biotic, and abiotic factors. • Give two examples of biotic and abiotic factors. • What is a keystone species? • What does every ecosystem include?
