  1. Ecology Unit Studying life, on the broad scale. Mr. Roes Living Environment

  2. The Earth. A whole lot of it. That’s the scope of focus for our unit on ecology. “The earth is what we all have in common.” ~Wendell Barry

  3. What is Ecology? • Ecology is the study of the interactions between organisms and their surroundings. • How could you describe what you see here?

  4. Where are all those organisms? • The area of the earth where all of the living organisms are found is called the biosphere. • Where are the living things found?

  5. Biomes • We divide up the biosphere into six different types of biomes. • Tropical Rainforest • Savannah/ Grasslands • Desert • Temperate Deciduous Forest • Boreal Forest • Tundra

  6. A biome is an area or a group of areas with a similar climate. Usually, a biome will have the same dominant communities.

  7. Ecosystems • An ecosystem is a collection of all of the organisms that live in a particular place, together with their physical environment.

  8. Community • All of the organisms in an ecosystem. A community is the total group of organisms living in a distinct area. In a community, there can be hundreds or thousands of different species of organisms, but we don’t include anything nonliving.

  9. Population The grand total of all of the individuals of a certain species living in one area. Like communities, populations never include nonliving things!

  10. Organism One individual living creature. In ecology, individual organisms are typically the smallest unit of study focused upon.

  11. The Biosphere The total area of our planet where life can be found.

  12. Savannah Tundra Desert Grasslands Boreal Forest Tropical Forest Temperate Forest

  13. A biome is an area or a group of areas with a similar climate. Usually, a biome will have the same dominant communities.

  14. Working with a partner, organize the following factors in your packet. The area has four seasons throughout the year. Dall Sheep live here. Grasses and shrubs grow during the summer The area doesn’t Receive much sunlight Shrubby plants grow in areas with soil. Lichen readily grow on exposed rocks. The climate is cold . There is only a very thin layer of soil There are especially harsh winters here There is a high speed of erosion Arctic squirrels live here and eat the seeds of grasses and sedges. The summer and fall seasons can become dry Very fast winds are common The location is at a high altitude.

  15. What will this ecosystem look like?

  16. Compare the following ecosystems:

  17. Ecosystems • Why were those ecosystems so different? • What forces shaped them to their current states?

  18. Ecosystems • We can divide the forces that shape an ecosystem into two groups: Biotic and Abiotic. • Biotic—Any of the living factors that affect an organism in its environment. • Abiotic—The nonliving chemical and physical properties of an environment.
