ECOSYSTEMS AND COMMUNITIES

CLIMATES Weather: condition of the atmosphere at a specific time/place Climate: average condition of atmosphere for an extended period of time Trapping of heat Latitude Ocean currents

GREENHOUSE EFFECT Trapping of CO2, CH4, H2O, and other gasses Keeps planet warm when not facing the sun 30 degrees Celcius cooler without greenhouse gasses

EFFECT OF LATITUDE/LONGITUDE 3 main climate zones Polar: low angle of light energy Temperate: most temp range depending on season Tropical: direct sunlight year round

ECOSYSTEMS Biotic factor: any living thing in an ecosystem Abiotic factor: any nonliving thing in an ecosystem Habitat: includes both abiotic and biotic factors (address of an organism) Niche: job of an organism Place in food web, range of temperatures needed, combo of biotic/abiotic factors

COMMUNITY INTERACTIONS Competition: organism/species competing for resources Predation: organism eating another organism Symbiosis: 2 species living in close proximity Mutualism: 2 species benefiting from each other Commensalism: one organism benefited, one not affected Parasitism: one organism benefited, one harmed

ACTIVITY Under your notes, draw and color a picture for each of the community interactions. Under each picture, write a short (1-2 sentences) description of each interaction, as well as how your picture shows that interaction.
