How are the number of zebras in an ecosystem effected by the amount of lions in that same ecosystem? Identify a possible controlled variable.
- 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
When energy changes from one type of energy to another (different) type of energy
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)
- Also known as heat - Type of energy lost to the environment as an organism naturally releases heat (body temperature)
- Original source of energy for a food chain - Energy source that powers photosynthesis
Number of zebras
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
Type of Ecosystem
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 zebra's kinetic energy when it runs.
Amount of lions
Glucose and Oxygen
- Form of energy each organism in a food chain is - Passes along from 1 organism to another as one is eaten
