Explanation:
Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations.
The given blank can be filled with enzymatic molecules.
Enzymes refer to biological molecules or proteins, which function as catalysts and assist the composite reactions to take place everywhere in life. The enzymes generally end with the suffix - ase. For example, proteases, which functions to dissociate the peptide bonds between the amino acids.
Enzymes are big molecules, which accelerate the rate of chemical reactions within the cells, and like all other kinds of proteins, they comprise lengthy chains of amino acids.

Answer:
birds
Explanation:
<em>Archaeopteryx</em> is an iconic fossil bird that lived during the Late Jurassic, approximately 150 million years ago. <em>Archaeopteryx</em> is iconic because it is a transitional fossil between non-avian dinosaurs (reptiles) and birds. The osteology of <em>Archaeopteryx</em> indicates that it was similar to that of nonavian theropod dinosaurs, i.e., dinosaurs characterized by hollow bones and three-toed limbs. Unlike modern birds, <em>Archaeopteryx</em> had a full set of teeth, a long tail, three fingers with claws and hyperextensible second toes commonly known as 'killing claws'.
