Why do organisms need energy? Flashcards
Why is ENergy needed for life?
Energy is needed by organisms to do chemical and physical work and keep life processes (MRSGREN) going.
What store do organisms use in food?
Organisms use chemical stores of energy in food. If they have more energy than they need, they can keep a chemical store of energy for later use.
what is a producer?
Some organisms are producers and are able to make their own food and biomolecules for growth by photosynthesis.
what is a consumer?
some organisms are consumers and must consume other organisms for energy
energy transfer
When energy is released from food and used for life processes, it is transferred from a chemical store to another store. For movement, this is a transfer from a chemical store to a kinetic store.
