“Energy flows through and nutrient cycle within an ecosystem. “ Sun to the ecosystem and leaves as heat. however the nutrients flow in circles unlike the sun to heat. Solar energy: -> chemical energy , photosynthesis. 6 Co2 6 H20 = C6 H12 O6 (sugar glucose) + 6 O2 ( hexagon is a glucose) //yellow as energy color// 3 ways to process energy; Burn, Build, Store Burn: cell respiration ::backwards of photosynthesis:: ATP- universal energy molecules. Build: in plants cell walls:: cellulose, Store: in plants : starch. chains of sugar. Trophic levels: Producers; Plants. .. photosynthetic organisms Autotrophs. Consumers; Animals Hetrotrophs: eaters of produces Primary consumers : herbivores ( leaf eaters ((long an complex guts)), fruit((shorter then leaf eaters)) , seed ect.) Secondary consumers: eat meat. . carnivores shorter digestive tracts Teeth::: Molars vs. Canine Day #3 omnivore- all , devourer. eats plants and animals. .. hybrids look similar to both other types of digestive straitest. detritivores- they eat dead bodies. animal and plant bodies.
