Fill in the Blanks Fill in the blank - Energy Transfers in EcosystemsOnline version Fill in the blank - Energy Transfers in Ecosystems by Benjamin D Morgan 1 ORIGINAL ENERGY EATEN HEAT TEMPERATURE ATP ENVIRONMENT TRANSFER PHOTOSYNTHESIS RESPIRATION DIRECTION TRANSFORMATION The process of requires CO2 and water while respiration produces CO2 and water . However , requires glucose and oxygen while photosynthesis produces glucose and oxygen . When energy moves from one organism to another organism in a one - way it's known as an energy and when energy changes from one type of energy to another type of energy it's known as an energy Chemical energy is a form of energy where each organism in a food chain is passed along from one to another as they're . Thermal energy also referred to as energy is lost to the environment to maintain body . Solar energy is the source of energy for a food chain and powers photosynthesis MATTER constantly keeps getting recycled and never leaves an ecosystem . Examples of matter include ; CO2 , H2O , C6H12O6 , and O2 . However , flows in a one way direction . Engery flows from the sun to chemical energy in plants to chemical energy in animls . is the energy used by each organism for growing , movement , and reproduction . Heat energy is lost to along the way .
