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 Photosynthesis Makes AND Respiration Needs 3 Chemical Energy 4 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the Independent variable. 5 Energy Transformation 6 Energy does this in an ecosystem/food web 7 Matter does this in an ecosystem/food web 8 How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the dependent variable. 9 Solar Energy 10 Thermal Energy 11 Energy Transfer 12 Energy Transfer and Transformation Statement 13 Photosynthesis Needs AND Respiration Makes .... 14 Energy Transfer Statement 15 Energy Transformation Statement Carbon dioxide and Water 1. When energy moves from one organism (object) to another organism (object) in a one-way direction. 2. Doesn't recycle Glucose and Oxygen Amount of lions - 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 - 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) When energy changes from one type of energy to another (different) type of energy Statement: The zebra's chemical energy becomes the zebra's kinetic energy when it runs. 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) Type of Ecosystem Statement: The zebra's chemical energy becomes the lion's chemical energy when the lion eats the zebra - Form of energy each organism in a food chain is - Passes along from 1 organism to another as one is eaten 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)
