Question 1 Report
Which of the following sets is made up of decomposers?
Decomposers are organisms that break down dead organic matter into simpler inorganic substances. From the given options, the set that is made up of decomposers is "Mushroom, rhizophus and bacteria." Mushrooms are fungi that play a significant role in breaking down dead organic matter in the environment. They secrete enzymes that digest organic matter and convert it into simpler inorganic compounds. Rhizophus is a type of fungi that is also involved in the decomposition of dead organic matter. Bacteria are another group of decomposers that play an essential role in the breakdown of dead organic matter. They can break down complex organic compounds into simpler inorganic compounds. On the other hand, earthworms, nematodes, and platyhelminthes are not decomposers. Earthworms feed on organic matter, but they are not decomposers as they do not break down the organic matter into inorganic substances. Nematodes and platyhelminthes are also not decomposers but rather are considered as consumers in the food chain, feeding on other organisms. Therefore, the correct answer is "Mushroom, rhizophus and bacteria."
