<span>Enzymes are called biocatalysts because they function in chemical reactions that involve living organisms [biologial organisms]. Enzymes generally increase the rate of metabolic reactions by lowering the activation energy, making it easier for the reaction to occur easily and rapidly. Without enzymes, some metabolic reactions may take a very long time before they are completed. Enzymes used in laboratory chemical reactions are not biocatalysts because they are not catalysing reactions in biological organisms. </span>
Answer:
2. synthesize its own food
Explanation:
Based on how they obtain their nutrition, living organisms has been classified to be either producers, consumers, or decomposers. Producers are organisms capable of synthesizing their own food using light (photosynthesis) or inorganic chemicals (chemosynthesis).
Consumers, on the other hand, cannot synthesize their own food and hence, rely on other organisms to obtain their energy source. Consumers feed on other organisms to obtain energy. In this question, a fruit fly is classified as a CONSUMER because it cannot synthesize its own food.
The answer is B .
Biotic factor refers to living things .
