38. What would occur if all producers were removed from an ecosystem? A. There would be no change; producers are not essential for most ecosystems.B. The output of the sun would decrease.C. The number of consumers would increase.D. Decomposers would take over the role of the producers.E.Consumers would soon run out of food.Producers are necessary components of all ecosystems. They convert sunlight energy into chemical energy that can be used by consumers. Decomposers are themselves consumers, and unable to stand in for producers in an ecosystem.Blooms Level: 4.
