Trophic Categories: 1. Producers 2. Consumers 3. Detritus feeders and decomposers Producers = organisms that capture energy from the sun or from chemical reactions to convert carbon dioxide to organic matter Organic Matter vs. Inorganic Matter -Matter that makes up the bodies of living things generally characterized by the presence of carbon and hydrogen bonds. Most producers are green plants. 1. Autotroph i. Chemosynthetic bacteria ii. Green plants iii. Algae 2. Heterotroph i. Animals ii. Fungi iii. Protists (some) Consumers Primary consumers = {herbivores} {omnivores} secondary consumers, tertiary consumers etc. = {carnivores} Predator Prey Relationships: Predator: organism which does the feeding…show more content…
• nearly colorless, tasteless, and an odorless liquid. • the universal solvent; (rarely clean) • Water is the only common, pure substance found naturally in all three states of matter • Highest density at 4˚C due to hexagonal crystal structure & hydrogen bond. • Polar nature The importance of this property cannot be overemphasized for its role on the ecosystem of Earth. If water were more dense when frozen, lakes and oceans in a polar environment would eventually freeze solid (from top to bottom). This would happen because frozen ice would settle on the lake and riverbeds. an important advantage for freshwater life in winter. • Surface water chills increases in density and sinks • convection currents form that cool the whole water body, • when the temperature of the lake water reaches 4 °C, water on the surface gains density and eventually forms ice. • downward convection of colder water is blocked by the density change, • coldest water forms near the surface, away from the riverbed or lakebed. Lithosphere: All other elements and minerals found in lithosphere Mineral: hard crystalline inorganic material of a given chemical composition Organic compounds: carbon-carbon, carbon-hydrogen bonds Inorganic compounds: have no C-C, or C-H bonds Natural organic/ synthetic organic Biogeochemical Cycles Carbon
