Explain how producers, consumers, and decomposers obtain the energy they need.

Producers obtain energy from sunlight, consumers obtain energy from producers, and decomposers obtain their energy from dead living beings.

Explanation:

Producers produce their food by themselves as they are autotrophic. They obtain mostly their food and energy from the light energy comes from the sun, by the process of photosynthesis.

Consumers are depending on producers for their energy and food. They get energy from producers they eat as food and convert energy from it.

Decomposers get their food or energy by decaying dead living beings or other organic matter. They change these organic matter to energy.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
