  1. Different Levels of organization studied by ecologists

  2. Biosphere- largest, most general • Total area where life exists, including land, water, and air

  3. Biome Coniferousforest Tundra • Large track of land with similar characteristics. • A group of ecosystems that have the same climate and similar dominant communities • Tropical rainforest, tropical dry forest, tropical savanna, desert, temperate grassland, temperate woodland/shrubland, temperate forest, northwestern coniferous forest, taiga (boreal forest), and tundra. Deciduousforest Grassland Temperaterainforest desert

  4. Ecosystem All the organisms that live in a particular place together (the community) with their nonliving, or physical, environment too! (the abiotic factors)

  5. Community • All BIOTIC factors in an area. • all animals, plants, protists, fungus, bacteria • Does NOT include the abiotic factors

  6. Population • Group of individuals of the same species living in the same area ground squirrel population A Flamingo population human population

  7. Habitat • Habitat is the area where an organism lives, including the biotic and abiotic factors that affect it

  8. Niche- the organisms role or “job” in the environment • A Niche is a full range of physical and biological conditions in which an organism lives and the way in which an organism uses those conditions. • What food does the organism eat? How does it get that food? What feeds on the organism? What temperature does it require? When does it mate? Harp Seal Profile • Harp seals spend relatively little time on land and prefer to swim in the North Atlantic and Arctic Oceans. These sleek swimmers cruise the chilly waters and feed on fish and crustaceans. They can remain submerged for up to 15 minutes. Harp seals are sometimes called saddleback seals because of the dark, saddlelike marking on the back and sides of their light yellow or gray bodies.Both sexes return each year to breeding grounds in Newfoundland, the Greenland Sea, and the White Sea. On this turf males fight for their mates, battling with sharp teeth and powerful flippers.When the mating ends, females gather in groups to give birth. Young harp seals are born on the ice, and mothers identify their own offspring from the multitudes by their smell. The young seals are famous for their snowy white coats.
