Unit 6: Flow of Energy Flashcards
Decomposition
the process y which decomposers break down dead material and waste into simpler substances.
Energy pyramid
a diagram that demonstrates the flow of the energy through the food chain.
Photosynthesis
the process by which producers/plats use the energy in sunlight to create their own food.
Trophic level
the position that an organism occupies in the food chain,food web, or energy pyramid (e.g., producer, primary consumer, etc.)
Chemical energy
the potential of a chemical substance to undergo a chemical reaction to transform into the other substances.
Consumer
animals that eat primary producers.
Decomposer
an organism, especially a bacteria or fungus, that decomposes organic material.
Food chain
a hierarchical series of organisms each dependent on the nest as a source of food
Food web
a system of interlocking and interdependent food chains.
Producer
an organism that makes its own food from light energy or chemical energy without eating.
Radiant Energy
the energy we get from the sun, includes infrared and ultraviolet energy.
Heterotroph
an organism that eats other plants or animals for energy and nutrients.
Thermal Energy
also known as heat energy, is the energy an object has because of the movement of its molecules.
Mechanical energy
the energy that is possessed by an object due to its motion.
