Energy Flow

2. an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms.
6. a consumer that feeds on dead plants and animals.
7. the movement of matter due to differences in density that are caused by temperature variations; can result in the transfer of energy as heat.
9. an organism that can make organic molecules from inorganic molecules; a photosynthetic or chemosynthetic autotroph that serves as the basic food source in an ecosystem.
11. the capacity to do work.
13. the transfer of energy as heat though a material
15. Pyramid a triangular diagram that shows an ecosystem’s loss of energy, which results as energy passes through the ecosystem’s good chain; each row in the pyramid represents a trophic (feeding) level in an ecosystem, and the area of a row represents the energy stored in that trophic level.
16. a community of organisms and their abiotic environment.

1. an organism that feeds by breaking down organic matter from dead organisms; examples include bacteria and fungi.
3. the energy that is transferred as electromagnetic waves, such as visible light and infrared waves.
4. an animal that feeds on the bodies of dead animals.
5. an organism that eats both plants and animals.
8. an organism that eats other organisms or organic matter instead of producing its own nutrients or obtaining nutrients from inorganic sources.
10. an organism that eats only plants.
12. Web a diagram that shows the feeding relationships between organisms in an ecosystem.
14. an organism that eats animals.
