Final answer:
Decomposers, including bacteria and fungi, indeed use enzymes to break down organic matter, which is a true statement. They are essential for nutrient recycling in ecosystems.
Step-by-step explanation:
The answer to whether some decomposers use enzymes to break down matter is A) True. Decomposers, which include bacteria and fungi, play a crucial role in ecosystems. They break down dead organisms, plant remains, and waste products, using enzymes to convert this material into simpler inorganic substances.
These substances are then recycled back into the ecosystem, providing essential nutrients for producers like plants. Saprotrophs, a type of decomposer that includes fungi, are particularly adept at this process, breaking down tough organic materials such as wood by secreting digestive enzymes.
