Why are bacteria and fungi called decomposers? List any two advantages of decomposers to the environment. 

Answer»

Bacteria and fungi breakdown the dead remains and waste products of organisms. These micro organisms are called the decomposers as they breakdown the complex organic substances into simple inorganic substances that go into the soil and are used up once more by the plants. 

Two advantages of decomposers to the environment are as follows: 

  • Decomposers feed, on the dead bodies of plants and animals. They return the simple components to soil and help in making the steady state of ecosystem by recycling of nutrients. They, therefore, create a balance in the environment. 
  • They also act as scavengers or cleansing agents of the atmosphere
