  1. What do the wolves in this picture represent? • Population • Ecosystem • Community • Biome

  2. Which of the following could be the wolves COMMUNITY? • All the populations of wolves in that biome • The wolves, and the moose • The wolves and the soil

  3. Everything in this picture would add up to a/an… • Population • Biome • Ecosystem • Species

  4. The Atmosphere, Water and Soil pictured below are examples of… • Biotic Factors • Abiotic Factors • Ecosystem • Population • Community . . . . . .

  5. The rabbit and wolf below represent a/an… • Biotic Factors • Abiotic Factors • Ecosystem • Population • Community . . . . . .

  6. Intro to ECOLOGY (Chapter 33) 33.1

  7. The study of the interaction of organisms with each other and their physical environment

  8. Organisms are organized into: ONE species! More than ONE species! • Populations – ex: Perch • (Members of a species living in an area) • Communities–ex: Perch, Walleye, Algae • (All the populations in an area) • Ecosystems–ex: Fish, Algae, Rocks, water • (A community and its physical environment) • includes biotic and abiotic factors • Biomes–ex:Tundra, Rainforest • (A large group of similar ecosystems containing distinct types of plants, animals, etc…determined by climate) • Biosphere • (all the communities on Earth whose members exist in air, water, and on land) Adds NONliving components!

  9. How do populations grow? • BIOTIC POTENTIAL: highest possible per capita rate of increase for a population • Per capita rate of increase= (Births-Deaths) / # of individual • LIMITING FACTORS: (create environmental resistance) • Biotic-living parts of the ecosystem • vegetation, etc • Abiotic – nonliving parts of the ecosystem • Precipitation • Temperature • Inorganic nutrients

  11. Has two phases: Lag phase: growth is slow because the population is small Exponential Growth Phase: growth is accelerating, and the population is exhibiting BIOTIC POTENTIAL. Cannot usually continue for long because of … Exponential Growth…J curves

  12. Environmental Resistance & Carrying Capacity • Environmental Resistance: all the environmental conditions that prevent populations from reaching their biotic potential • Ex: limited food supply, accumulation of waste, predation, competition…(biotic and abiotic limiting factors) MOST populations taper off around their… • Carrying Capacity: # of individuals the environment can normally support We call this kind of growth…

  13. This creates an “S shaped curve” Four phases: Lag Exponential growth Deceleration phase (pop growth slows) Stable equilibrium phase/stationary phase (births and deaths start to even out) Logistic Growth 1. Where is the carrying capactiy in this curve?
