How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the dependent variable.
How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify a possible controlled variable.
Energy Transfer and Transformation Statement
How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify the Independent variable.
1. When energy moves from one organism (object) to another organism (object) in a one-way direction. 2. Doesn't recycle
When energy changes from one type of energy to another (different) type of energy
- Also known as heat - Type of energy lost to the environment as an organism naturally releases heat (body temperature)
Glucose and Oxygen
- Original source of energy for a food chain - Energy source that powers photosynthesis
Type of Ecosystem
Carbon dioxide and Water
- Form of energy each organism in a food chain is - Passes along from 1 organism to another as one is eaten
- 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 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)
Number of zebras
Amount of lions
Statement: The zebra's chemical energy becomes the lion's chemical energy when the lion eats the zebra
- 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)
