Verified step by step guidance1
Step 1: Understand the question is asking for a term that describes living organisms essential to many life processes.
Step 2: Recall that 'microorganisms' are living organisms, often microscopic, such as bacteria, fungi, and some protists, which play vital roles in ecosystems and human health.
Step 3: Recognize that 'viruses' are not considered living organisms because they cannot reproduce or carry out metabolism independently.
Step 4: Note that 'enzymes' are biological molecules (proteins) that catalyze chemical reactions but are not organisms themselves.
Step 5: Understand that 'antibodies' are proteins produced by the immune system to fight pathogens, not living organisms.
