  1. Introducing

  2. Eco logy Ecology the study of the relationships between biotic and abiotic factors in environments eco(G) root home, abode log, -o, y(G) suffix study of ecoclimate ecosystem ecotourism epidemiology climatology zoology

  3. Bio Biotic Factors include plants, animals, fungi, microorganisms bio(s), bio(t)(G) root life biosphere biotechnology biofeedback biostatistics biotic biography biology biomechanics

  4. Examples of Biotic (living) Factors

  5. A Abiotic Factors include air, water, soil, temperature, wind, source of energy (usually sun) a, an(G) prefix not, without abiotic amoral atoxic

  6. Examples of Abiotic (non-living) Factors

  7. Biome a large geographic area with specific plant and animal groups. The climate and other abiotic factors determine what type of biome exists.

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

  9. What biome do we live in? Have you lived in another biome?

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

  11. How do abiotic factors change as the seasons change? • 2.How do biotic components change from summer to winter?

  12. Ecosystem A unit, small or large, that consists of biotic factors (plants, animals, micro-organisms functioning together with abiotic factors (precipitation, sunlight, soil).

  13. Ecosystems do not necessarily have clear boundariesdue tobiotic (living)andabiotic (non-living)changes can change daily as things move from one ecosystem to another Biotic Abiotic migration, seed dispersal flood, erosion, drought

  14. Biotic Factors : interact with each other in complex ways Predator Prey and competition such as Plants and animals dependent upon water, minerals, temperature, light also interact with abiotic factors in the ecosystem such as

  15. How does temperature affect your life? (abiotic on biotic) • 2. How do predators affect other living systems? (biotic on biotic)

  16. Building from smaller to larger, many ecosystems can be connected to form an An Ecoregion is a unit of land or water that contains a definable group of species, natural communities, and environmental conditions. Dallas is a part of the Blackland Prairie ecoregion. You will be studying your ecoregion this year! Ecoregion.

  17. Can you find our Ecoregion? What color? There are 10-13 ecoregions in Texas

  18. Ecoregions together make up what?? The difference between “ecoregion” and “biome” is one of scale. Biomes are larger and include several ecoregions.
