Energy in the Ecosystem Photosynthesis – Light (radiant energy) collected in plant transforms into Chlorophyll (chemical energy) Autotrophs – Plants are responsible for transforming radiant energy to chemical energy. Heterotroph – Animals, Protists, Fungus and Bacteria consume to gain chemical energy. o Herbivore – Eats only plants o Omnivore – Eats plants and animals o Carnivore – Eats only animals o Detritivore – Scavenges or breaks down dead organisms Radiant Energy – Sun Chemical Energy – Food Mechanical Energy – Movement Food Chain – Single flow of energy through organisms Food Web – Multi flow of energy through organisms Food Pyramid – Diagram of energy transfer through trophic levels Trophic Level – class of organisms that receive the same amount of energy in an ecosystem 90/10 Rule – organisms gain 10% chemical energy & spend 90% mechanical energy 6CO₂+6H₂O C₅H₁₂O₆+6O₂ - Carbon dioxide & water using light to make chlorophyll sugar Abiotic – Nonliving matter (Air / wind, Heat & Light / Sun, Nutrients / Soil, Gravity/ force) Biotic – Living organisms (Animals, Plants, Protists, Fungus, Bacteria) Ecosystem –Biotic organisms interacting with abiotic factors for survival Biomass – amount of living matter in a habitat Energy in the Ecosystem Photosynthesis – Light (radiant energy) collected in plant transforms into Chlorophyll (chemical energy) Autotrophs – Plants are responsible for transforming radiant energy to chemical energy.
