Q: Answer the following question given this paragraph: Food chains carry energy from producers (autotrophs) to consumers (heterotrophs). 99% of energy for life comes from the sun via photosynthesis. Note that only nutrients recycle. Energy must continue to flow into the system. Though this food chains "ends" with decomposers, do decomposers, in fact, digest matter from each level of the food chain? (See the Energy Transfer: Decomposers (Advanced) concept). Q: Food chains carry energy from what group to what group? Choices: - consumers to producers - decomposers to producers - refiners to consumers - producers to consumers A:
A: producers to consumers
Question: Answer the following question given this paragraph: Humans have been making and using magnifying lenses for thousands of years.

Q: Answer the following question given this paragraph: Tubeworms deep in the Galapagos Rift get their energy from chemosynthetic bacteria. Tubeworms have no mouth, eyes or stomach. Their survival depends on a symbiotic relationship with the billions of bacteria that live inside them. These bacteria convert the chemicals that shoot out of the hydrothermal vents into food for the worm. Q: From what do tubeworms found deep in the galapagos rift get their energy from? Choices: - chemosynthetic plants - chemosynthetic fish - chemosynthetic viruses - chemosynthetic bacteria A:
A: chemosynthetic bacteria
