Eco Pp

  1. 1. Ecosystems<br />large <br />Small to <br />
  2. 2. Biotic: living things<br />Ex- tiger, venus fly trap, bacteria, fungi, ants<br />Abiotic: nonliving things<br />Ex- weather, soil, rock, sunlight, wind<br />Temperature affects the density of substances, and changes in the density of water means more or less resistance for animals who are travelling in the freshwater environment.<br />Biotic vs. Abiotic<br />
  3. 3. Organism- <br />Species - a class of plants or animals whose members have the same main characteristics and are able to breed with each other<br />The organism panda, are an endangered species. <br />Organism<br />a living thing that has (or can develop) the ability to act or function independently <br />
  4. 4. Population- group of individuals in the same area, species and time <br />Diversity within a population- Pacific Ocean<br />A population can become more diverse by immigration or emigration.<br />A population can become less diverse by selective breeding or fragmentation .<br />Diversity within a population is good because a change in environment cannot kill everyone or a disease won’t kill species at once.<br />Population<br />
  5. 5. Community <br />Community- a group of interacting organisms sharing an environment<br />Biodiversity- variety of all forms of life, from genes to species, through to the broad scale of ecosystems <br />Communities with more biodiversity can signify that the area is simply easier to live in. One thing that can cause a high biodiversity is low pollution levels. <br />A community consists of the abiotic environment and the populations of living organisms that reside in that environment. <br />
  6. 6. Ecosystem- groups of population including nonliving <br />A community doesn’t include nonliving like an ecosystem does.<br />A ecosystem can fragment by less random mating which causes more inbreeding, highways or weather change.<br />Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.<br />Ecosystem <br />
  7. 7. Biosphere-part of planet where life can live.<br />Relatively thin life-supporting stratum of the earth&apos;s surface, extending from a few miles into the atmosphere to the deep-sea vents of the oceans. The biosphere is a global ecosystem that can be broken down into regional or local ecosystems, or biomes.<br />3% of water is fresh <br />97% of water is salt <br />30% land<br />Biosphere <br />
  8. 8. Evolution<br />Evolution-change in the genetic material of a population of organisms through successive generations<br />Natural selection- process by which heritable traits that make it more likely for an organism to survive and successfully reproduce <br />Selective breeding- process of breeding plants and animals for particular genetic traits<br />How an organism envolved<br />
