I Would go with Producers, since plants take nitrogen from the soil to make amino acids, & plants are considered producers. Hope this helps :)
I believe it is A.Autotrophs because carnivores gather their energy from eating meat and herbivores gather their energy from plants
Answer: The Cell structure.
Explanation: Most Archaeas don't have membrane-bound organelles, they are mostly unicellular prokaryotic organisms.
Archaea are found living alongside bacteria in many environments. Recently Archaea belongs to Crenarchaeota have been implicated in nitrogen cycling in the soil.
Fungi are eukaryotic multicellular organisms and they have membrane-bound organelles. they are hence more closely related to plants and animals than to bacteria or archaea. Like eukaryotes, Fungi has nuclei with chromosomes that contain DNA. They possess membrane-bound organelles such as mitochondria. Fungi are heterotrophs, and they are saprophytic, they feed on decaying matter. some fungi occur as unicellular organisms, they are generally referred to as yeasts.
A monomer is a small molecule that may become chemically bonded to other monomers to form a polymer.
