Slide 1 - Ecology Is the study of Living Things (Biotic Factors) and their Environment (Abiotic Factors)

Slide 2 - Ecology Research People who study Ecology are Ecologist! Quantitative Descriptive MeasurementsObservations

Slide 3 - Biotic Factors All the living organisms in an environment! All organisms are affected by the others that they live around!

Slide 4 - Abiotic Factors The non-living parts of an organism’s environment. (e.g. temp, light, moisture, soil).

Group A Group B Slide 5

Slide 6 - Population When there’s more than one organism of the same species in an area.

Slide 7- Community All the different species in an area. No species is ever by itself!

Slide 8 Biological Community Cont. A change in one population can affect another population!

Slide 9 - Ecosystem Community and the non-living environment OR Biotic Factors + Abiotic Factors

Slide 10 – Biomes All the ecosystems on Earth that have similar climates and organisms. Aquatic Biomes (Water) Terrestrial Biomes (Land)

Slide 11 – Climate Latitude determines temperature! As you move from the equator to the poles, temperatures get colder! DegreesZone 0° - 30°Warmest 30° - 60°Cooler °Coldest

Slide 12 - Aquatic Biomes Approximately 75% of Earth’s surface if water. Both contain salt, but salt water has more than freshwater! Salt Water Biomes  Oceans  Seas  Some Inland Lakes (e.g. Salt Lake) Freshwater Biomes  Rivers  Streams  Ponds  Most lakes

Slide 13 - Ocean Layers of the ocean support different organisms. More organisms found at the surface of water. Photic Zone = Receives sunlight Aphotic zone = No Light.

Slide 14 - Plankton Organisms that live on the surface where there’s light. They are the main source of food for other marine organisms.

Slide 15 - Rivers All rivers flow into the ocean. Estuary Place where rivers and oceans connect. Gets saltier as you get move closer from river to ocean.

Slide 17 - Types of Trees Grouped based on types of leaves! Conifer Deciduous

Slide 18 - Tree Question Tree A Tree B

Slide 19 - Poles Ground is always frozen (Permafrost). Plants need to put their roots in the ground. No trees because they have no place to put their roots.

Slide 20 - Types of Organisms Each Biome supports different organisms. BiomePlantsAnimals Tundra (Poles)No trees! Only small plantsPolar Bears Taiga (Alaska)Conifer TreesBrown Bears Temp Rain Forest (Oregon)Deciduous TreesDeer Desert (Arizona)CactusLizards Tropical Rain Forest (Hawaii)Tropical PlantsTropical Fish

Slide 21 - Tropical Rain Forests The forests have 3 layers. LayerName TopCanopy MiddleUnderstory BottomGround

Slide 22 - Biodiversity The amount of different species in an area. Rain Forests have the greatest biodiversity!

Slide 23 - Biosphere The portion of Earth that supports life.

Slide 24 - Biosphere Cont. All places one Earth where life is found. The Biosphere is not very big compared to Earth’s size.

Slide 25 Levels of Organization Summary

Slide 26 - Habitat The place where an organism lives out its life.

Slide 27 - Niche What an organism uses for food and shelter.

Slide 28 - Symbiosis When two organisms live close together! SymbiosisWho benefits and is hurt?Examples MutualismBoth Species BenefitHumans + Intestinal Bacteria CommensalismNone benefits or is hurtTree + Moss ParasitismOne benefits, other hurtFlea + Chunk
