Primary consumers .

a. receive energy directly from the sun
b. make their own food using photosynthesis
c. break down dead matter into chemical nutrients

D. Are the first to receive energy from a plant.

Explanation: Paying attention to the trophic level in which the food chain occurs is key. Producers are the ones that receive energy directly from the sun. They also make their own food using photosynthesis. A decomposer is the one who breaks down dead matter into chemical nutrients. Therefore, Primary consumers are the first to receive energy from a plant.

I hope this helped!

Good luck <3

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
