The answer is, all three carbons from glucose molecules enters the Kreb cycle. But three at a time only. One molecule is broken down to two pyruvate molecules and then used in Krebs cycle. Which means that one glucose molecules leads to two cycles of the Kreb cycle with three carbons going to the cycle at one time.

Answer:
The correct answer is - sun - producer - the consumer – decomposer.
Explanation:
Sun is the ultimate source of the energy on the earth and is responsible for all the energy that is present or moves between various organisms in an ecosystem.
Sun provides energy in the form of light energy which is converted by the producers by photosynthesis into food and when consumers eat producers for food and energy 10 percent of energy passes from the producers to the consumers and the rest 90% lost during life processes. At the end of the chain, decomposers get energy from the dead matter of the consumers.

You would expect an earthworm to have no exoskeleton because as you see it is very flexible and soft. Organisms with such have body parts that are divided and an earthworm do not have any visible parts on them also having an exoskeleton would not allow an organism to move like an earthworm does.
