Answer:
X: Producers undergo photosynthesis;
Y: Decomposers return carbon to the soil and release waste
Explanation:
Producers, for example, a clover, will take the CO2 in the atmosphere and use it in photosynthesis to turn it into nutrients, then the consumers, for example, a deer, will eat the producer to gain nutrients. After the consumer dies, the decomposer, for example, fungus, will eat away at the consumer, releasing CO2 into the atmosphere. Then the cycle keeps going.
