Question

there are little bacteria that live in ponds. these bacteria take in energy from the sunlight and convert it to energy that they can use. these organisms are: primary consumers decomposers producers tertiary consumers secondary consumers

Producers are organisms that can convert sunlight (or other inorganic sources) into energy (like through photosynthesis). Primary consumers eat producers, secondary consumers eat primary consumers, tertiary consumers eat secondary consumers, and decomposers break down dead organic matter.
