Presentation on theme: "The Abiotic and Biotic Environment"— Presentation transcript:
1 The Abiotic and Biotic Environment EQ: How can we classify the levels of ecological organization?
2 Ecology is…the study of the interactions among organisms and their environment.
3 Biotic 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
4 Summarize What is the difference between biotic and abiotic factors? Give an example of each.
5 Organization 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.
6 Organization 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
7 Organization 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
8 Ecosystem – 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
9 SummarizeWhat are the levels of ecological organization from smallest to largest?
10 Draw 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
