Organism • An organism is a living specimen that is a member of a specific species.
Population • A population is a group of individuals of the same species that live in the same area.
Community • A community is a grouping of different populations that live together in a defined area.
Ecosystem • An ecosystem is the collection of all of the organisms in a particular place, combined with the nonliving environment.
Carbon Cycle • involves the processes of respiration and photosynthesis. • In respiration, oxygen and glucose are combined releasing energy and producing water and carbon dioxide. • In photosynthesis water and carbon dioxide along with the energy from the sun are combined to produce glucose (containing energy) and oxygen. • Each process compliments the other and the ecosystem maintains its balanced communities.
Cellular Respiration Equation • C6H12O6 + 6O2 -> 6CO2 + 6H20 + Energy Carbon Dioxide Glucose ATP Oxygen Water Reactants Products
Cellular Respiration & Photosynthesis • 6O2 + C6H12O6 → 6CO2 + 6H2O + Energy • oxygen + glucose carbon dioxide + water + Energy • 6CO2 + 6H2O +light energyC6H12O6 +6O2 • carbon dioxide + water sugars + oxygen
6CO2 + 6H2O +light C6H12O6+6O2 • 6O2 + C6H12O66CO2 + 6H2O + Energy
Nitrogen cycle • Nitrates (used by plants) • Build plant proteins • Eaten by animals • made into animal proteins • Plants and animals die • bacteria decay • Ammonia (NH3) • Nitrifying Bacteria • Nitrates (used by plants)
Water Cycle • involves the processes of photosynthesis, transpiration, evaporation and condensation, precipitation, and runoff and groundwater movement
