Cycles Daily Rhythms diurnal – active at day
Cycles Daily Rhythms diurnal – active at day nocturnal – active at night
Cycles Lunar Rhythms
Cycles Lunar Rhythms tides – high / low monthly cycles
Cycles Annual Rhythms
Cycles Annual Rhythms seasonal changes
Cycles Annual Rhythms seasonal changes migration – annual movement from breeding to feeding grounds
Cycles Annual Rhythms seasonal changes hibernation – winter resting state (Latin: hibernus – “winter”)
Cycles Annual Rhythms seasonal changes estivation – summer resting state (Latin: aestivus – “summer”)
Cycles of Matter Flow of matter (chemicals) from non-living (abiotic) to living (biotic) parts of an ecosystem, and back again
Cycles of Matter Water Cycle: - evaporation (liquid to gas)
Cycles of Matter Water Cycle: - evaporation - condensation (gas to liquid) (cloud formation)
Cycles of Matter Water Cycle: - evaporation - condensation - precipitation (rain, snow, sleet, hail, fog)
Cycles of Matter Water Cycle: - evaporation - condensation - precipitation - infiltration / runoff (groundwater, streams, oceans)
Cycles of Matter Oxygen – Carbon Cycle:
Cycles of Matter Oxygen – Carbon Cycle: - photosynthesis (producers: take CO 2 O 2 )
Cycles of Matter Oxygen – Carbon Cycle: - photosynthesis (producers: take CO 2 O 2 ) - respiration (consumers: take O 2 CO 2 )
Carbon – Oxygen Cycle
Cycles of Matter Nitrogen Cycle:
Cycles of Matter Nitrogen Cycle: - fixation: bacteria change “free” N from air to N- compounds in soil
Cycles of Matter Nitrogen Cycle: - metabolizing: N-compounds moved from soil to plants to animals
Cycles of Matter Nitrogen Cycle: - decomposition: bacteria “free” N back to air again
Cycles of Change Ecological Succession: - gradual change from one community to another
Cycles of Change Ecological Succession: - gradual change from one community to another Climax Community:
Cycles of Change Ecological Succession: - gradual change from one community to another Climax Community: - a stable community of organisms
