Ecology As we look at the following pictures – identify any words that “fit” or come to mind.
What is Ecology? • After looking at the pictures, how would YOU define Ecology. Write it down in NB • “ecos” = home • “ology” = study of • Ecology = the study of organisms and where they live
What is an Ecosystem? • First, we need to define system. • Handout
In your NB… • Explain your thinking. How did you decide whether something was considered a system or not a system? • System:an organized group of related objects or components that form a whole.
Which ones are NOT Systems? • aquarium digestion cell phone • pile of sand food web A + B = C • Earth hurricane electrical circuit • grasshopper graph water cycle • Volcano seed human body • Soil bicycle D = M/V • Ocean Earth and moon box of nails
Define Ecosystem in your NB • Ecosystem = a systemformed by the interaction of organisms with the living (biotic) and non-living (abiotic) environment. • Abiotic Biotic
Video • Coral Reef Ecosystem • How might an abiotic factor affect a biotic factor in an ecosystem?
Organism • individual
Population • same species living together
Community • different populations living together
Ecosystem • includes both biotic (living) and abiotic (non-living) factors
Biomes • group of ecosystems that have the same climate and similar communities
Biosphere • Earth: land, water, air
Other Vocabulary • Niche: An organisms role, or “job” in the ecosystem
Other Vocabulary • Biodiversity – the variety of living organisms within an ecosystem.
What abiotic factors affect the biodiversity of an area? • Sunlight • Water • Temperature • Soil • Wind • Severe Disturbances • Which factor has the MOST affect on Biodiversity?
What determines the location of ecosystems on Earth? • The climate of a region • Climate patterns are largely produced by the uneven heating of the planet by the sun.
Thought Question… • Reflect on the biodiversity of the Tundra and Evergreen Forest biomes. Identify at least two reasons for the differences in biodiversity between these two places.
Succession • Pioneer species – the first species to move into a disturbed area. • Succession – when species replace other species in a given area. • Primary succession – occurs where life has not existed before. • Secondary succession – occurs in areas that have previous growth
