Matching Pairs Matching - Energy Transfers in EcosystemsOnline version Matching - Energy Transfers in Ecosystems by Benjamin D Morgan 1 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify a possible controlled variable. 2 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the dependent variable. 3 Matter does this in an ecosystem/food web 4 Energy Transfer 5 Thermal Energy 6 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the Independent variable. 7 Photosynthesis Needs AND Respiration Makes .... 8 Photosynthesis Makes AND Respiration Needs 9 Energy Transformation 10 Energy Transfer Statement 11 Chemical Energy 12 Energy does this in an ecosystem/food web 13 Solar Energy 14 Energy Transfer and Transformation Statement 15 Energy Transformation Statement 1. When energy moves from one organism (object) to another organism (object) in a one-way direction. 2. Doesn't recycle - 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 Number of zebras Type of Ecosystem - Also known as heat - Type of energy lost to the environment as an organism naturally releases heat (body temperature) - 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 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) Statement: The zebra's chemical energy becomes the lion's chemical energy when the lion eats the zebra Glucose and Oxygen Carbon dioxide and Water Statement: The zebra's chemical energy becomes the zebra's kinetic energy when it runs. - Original source of energy for a food chain - Energy source that powers photosynthesis - Form of energy each organism in a food chain is - Passes along from 1 organism to another as one is eaten When energy changes from one type of energy to another (different) type of energy
