1 Pages Section 1

2   Describe Abiotic and Biotic factors in your journal. Bell Ringer

3   Ecology  Study of the interactions among organisms and their environment. Ecologists  Scientists who study environmental relationships  Organize the environmental factors that influence organisms into 2 groups  ABIOTIC  BIOTIC The Environment

4   Abiotic  Non-living parts of the environment Examples: I.Water II.Light & Temperature III.Air IV.Soil Comparing Abiotic and Biotic Factors

5   Biotic Factors  Living or once-living organisms in the environment Examples: I.Levels or organization II.Population III.Communities IV.Ecosystems V.Biomes VI.The Biosphere Comparing Abiotic and Biotic Factors

6   Video Time

7   Describe the “biome” in which we live.  Must answer with at least 5 sentences. Be in depth and cover what is observed in this area. Bell Ringer

8  5 Factors:  Water  Light  Temperature  Air  Soil Abiotic Factors

9  1.Water  All organisms need water to survive  Organisms are made of 50%-95% water  Respiration, photosynthesis, digestion, and other important life process can only occur with presence of water  95% of Earth’s surface water is found in oceans Abiotic Factors

10  Examples of Water Pacific Ocean-Kauai, Hawaii Cumberland River & Lake Cumberland Dale Hollow Lake Bayou-Gueydan, LA

11  2. Light  Availability of sun light is a major factor in determining where green plants and other photosynthetic organisms live  Energy from Sun is changed into chemical energy  Algae-lives near water surface  Dense forest have very little photosynthetic plants, why? Abiotic Factors

12  Plant Examples North Shore-Kauai The Garden of Eden-Kauai Kipu Ranch-Kauai -conifers

13  3.Temperature  Regional temperature also determines which plants and animals can live there  Some areas of the world have fairly consistent temperature year round  Other areas have season during which temperatures vary  Arctic, Desert, Mid-Atlantic, Tropical, Arid, and Mild Abiotic Factors

14  Temperature Variations Mojave Desert-CA Arctic Plain-Antarctica Rain Forest-Brazil Great Plains-Kansas Appalachian Mts-TN Tropical Island-FL Keys

15  4.Air  Composed of a mixture of gases including Nitrogen, Oxygen, and Carbon Dioxide.  Plants & Animals depend on the gases in air for respirations (breathe)  All species are affected by weather  Weather- 8km to 16 km (from surface)  Ozone Layer-20km to 50km (from surface) Few organisms live at extreme air pressures Abiotic Factors

16  5.Soil  Varies greatly from one environment to another  Soil Type-determined by amount of Sand, Silt, and Clay it contains  Various soils contains different amounts of nutrients, minerals, and moisture Soil affects every organism in an environment! Abiotic Factors

17  Soil Top Soil-rich in nutrients and moisture (plant crops) Red Clay-sub soil-very acidic (use as filler dirt) Bed Rock-mostly limestone/sandstone (paving stone)

18   Abiotic Factors do not provide everything an organism needs for survival  Organisms depend on other organisms for:  Food  Shelter  Protection  Reproduction Biotic Factors

19  Biotic Factors Include:  Bacteria  Protists  Fungi  Plants  Animals Biotic Factors

20  1.Organism : one individual from a population Levels of Organization Mallard Drake “GreenHead ”

21  2.Population : all of the individual of one species that live in the same area at the same time. Levels of Organization

22  3.Community : the populations of different species that interact in some way Levels of Organization

23  4.Ecosystem : all of the communities in an area and the abiotic factors they interact with Levels of Organization

24  5.Biome : large region with plants and animals well adapted to the soil and climate of the region Levels of Organization

25  6. Biosphere : The level of biological organization that is made up of all the ecosystems on Earth Levels of Organization

26   Where Earth’s organisms live  Can be found  11,000 m deep in the ocean  9,000 m high on the mountains  4.5 km high in atmosphere Includes top part of Earth’s crust, all the waters that covers the Earth’s surface, the surrounding atmosphere, and all biomes! Biosphere Extremophiles
