Presentation on theme: "The Abiotic and Biotic Environment"— Presentation transcript:
1The Abiotic and Biotic Environment EQ: How can we classify the levels of ecological organization?
2Ecology is…the study of the interactions among organisms and their environment.
3Biotic vs. AbioticBiotic components of the environment: Living things that affect the ecosystem Ex. Grass, plankton, plants, insects Abiotic components of the environment: Non-living things that affect the ecosystem Ex. Water, sunlight, oxygen, temperature, soil
4Summarize What is the difference between biotic and abiotic factors? Give an example of each.
5Organization of an Ecosystem Individual – One organism, a single living thinghabitat- the place where an organism lives in order to obtain food, water, shelter and other things needed for survivalniche- the role of an organism in the environment- type of food it eats- how it gets its food- interactions with other organismsEx. The niche of a bee is to pollinate flowers as it gathers nectar for its food.
6Organization of an Ecosystem Population – All the individuals of a given species in a specific area or region at a certain time.Members of a population compete for food, water, space, and matesEx. Loblolly pines in SC
7Organization of an Ecosystem Community - All the different population in a specific area or region at a certain timeCommunities involve many types of interactions among populations: obtaining food, space, or other environmental factorEx. All of the crabs, seagulls, and sea grass at the beach are part of the same community
8Ecosystem – One or more communities in an area and the abiotic factors including water, sunlight, oxygen , temperature and soilBiome – Individual ecosystems grouped together according to climate and vegetationBiosphere – the ecosystem of planet Earth
9SummarizeWhat are the levels of ecological organization from smallest to largest?
10Draw your pyramid Fill in each level of the pyramid Include a description on the right of each levelBe sure to show and or list your individual’s habitat and niche
