Statement 1: The microorganisms like bacteria and fungi that convert dead and decaying animals and plants into humus are called decomposers.
Statement 2: Sometimes the organic matters in the sewage break down by anaerobic bacteria in a closed tank.
Explanation:
Decomposers and their Role:
- Decomposers are microorganisms, such as bacteria and fungi, that break down dead and decaying animals and plants into simpler substances.
- They play a crucial role in the ecosystem as they help in recycling nutrients and organic matter.
- These decomposers help to convert the dead organic matter into humus, which is a dark, nutrient-rich component of soil.
- Humus improves the fertility of the soil and provides essential nutrients for the growth of plants.
Sewage Treatment:
- Sewage is the wastewater from households, industries, and other sources.
- Sewage contains both organic and inorganic substances.
- The treatment of sewage is important to remove harmful substances and reduce environmental pollution.
- One method of sewage treatment involves the use of a closed tank, known as an anaerobic digester.
- In this process, organic matter present in the sewage is broken down by anaerobic bacteria, which can survive without oxygen.
- These bacteria convert the organic matter into simpler substances like methane gas and carbon dioxide.
- The anaerobic digestion process helps in reducing the volume of sewage and also produces biogas, which can be used as a source of energy.
Conclusion:
Both Statement 1 and Statement 2 are true.
- Statement 1 is true because decomposers, such as bacteria and fungi, play a vital role in converting dead and decaying animals and plants into humus.
- Statement 2 is true because some organic matters in sewage can indeed break down by anaerobic bacteria in a closed tank during the sewage treatment process.
Statement 2: Sometimes the organic matters in the sewage break down by anaerobic bacteria in a closed tank.
