Energy Transfers Flashcards
What is the law of conservation of energy?
Energy cannot be created or destroyed, only changed from one form to another.
What is a producer?
A photosynthetic organism that manufactures organic substances using light energy, water and carbon dioxide.
What is a consumer?
Consumers are organisms that obtain their energy by feeding on other organisms.
What is a decomposer?
When producers and consumers die, the energy they contain can be used by organisms that break down these complex materials into simple components again.
Why is there a lot of energy lost between trophic levels?
Some of the organism cannot be eaten. Once eaten, some of the organism cannot be digested. Energy is lost as body heat and respiration.
