1. Heterotrophs either eat autotrophs directly, or they eat some other organism that ate autotrophs. Heterotrophs also need the oxygen produced by autotrophs as they do photosynthesis.
2. ATP stores a much smaller amount of energy than a molecule of glucose. ATP is ready to be used for the cell's activities. Glucose must be broken down to release energy to build ATP. It's kind of like cashing a check. The check represents money, but you sure can't get a soda out of a machine with a check. You have to cash the check and get money that is ready to use. Cells have to cash in glucose to make ATP that is ready to use.
