Matching Pairs Matching - Energy Transfers in EcosystemsOnline version Matching - Energy Transfers in Ecosystems by Benjamin D Morgan 1 Photosynthesis Makes AND Respiration Needs 2 Solar Energy 3 Energy Transfer Statement 4 Photosynthesis Needs AND Respiration Makes .... 5 Energy Transformation Statement 6 Energy does this in an ecosystem/food web 7 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the dependent variable. 8 Energy Transfer 9 Chemical Energy 10 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify a possible controlled variable. 11 Matter does this in an ecosystem/food web 12 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the Independent variable. 13 Energy Transformation 14 Thermal Energy 15 Energy Transfer and Transformation Statement - This recycles over-and-over between organisms in a food web/ecosystem as one organism eats another. - It never leaves the ecosystem. It gets re-used. - Atoms in CO2, H2O, C6H12O6, and O2 move in a circular pattern Glucose and Oxygen 1. When energy moves from one organism (object) to another organism (object) in a one-way direction. 2. Doesn't recycle - Form of energy each organism in a food chain is - Passes along from 1 organism to another as one is eaten Statement: The zebra's chemical energy becomes the zebra's kinetic energy when it runs. Type of Ecosystem When energy changes from one type of energy to another (different) type of energy - Original source of energy for a food chain - Energy source that powers photosynthesis - Also known as heat - Type of energy lost to the environment as an organism naturally releases heat (body temperature) Statement: The zebra's chemical energy becomes the lion's kinetic energy when the lion digests the zebra and is able to get its heart to beat (kinetic) Number of zebras - Flows in a 1 Way direction - Solar turns to chemical (photosynthesis) - Chemical (ATP) moves from one organism to another as it is eaten - ATP energy is used by the organism (kinetic…growing, taking water up roots, heart beat, running, etc.) - Heat is lost to environment (body temperature) Amount of lions Statement: The zebra's chemical energy becomes the lion's chemical energy when the lion eats the zebra Carbon dioxide and Water
