A mouse $Hox$ gene can be used to take over the function of a mutated $Drosophila$ $Hox$ gene.\ See Page 1. 1. D) the increase in the average temperature across the continents Which type of organism uses water, carbon dioxide, and energy from the sun to make its own food? Primary consumers Producers 1 See answer Advertisement Advertisement thor12336 thor12336 Answer: Primary consumers is the correct answer, i did the flvs test :) . B) only II They take nutrients from organic matter left in the soil by decomposers and transform them into food for themselves and other organisms.

Fungi (like mushrooms) are decomposers that decompose organic matter and consume that as their source of energy. The primary producers include plants, lichens, moss, bacteria and algae.
