FAQs on The Role of Decomposers Video Lecture - Science Class 7
| 1. What is the role of decomposers in an ecosystem? |  |
Ans. Decomposers play a crucial role in an ecosystem by breaking down organic matter, such as dead plants and animals, into simpler substances. They help in the recycling of nutrients, releasing essential elements back into the environment for other organisms to use.
| 2. How do decomposers contribute to soil fertility? | |
Ans. Decomposers, like bacteria and fungi, break down organic matter in the soil. During this process, they release nutrients, such as nitrogen, phosphorus, and potassium, into the soil. These nutrients are then utilized by plants for their growth, thus enhancing soil fertility.
| 3. What are some examples of decomposers? | |
Ans. Examples of decomposers include bacteria, fungi, worms, insects like termites and beetles, and scavengers like vultures and certain species of crabs. Each of these organisms plays a role in the decomposition process, breaking down different types of organic matter.
| 4. How do decomposers help in waste management? | |
Ans. Decomposers aid in waste management by breaking down organic waste materials, such as food scraps, dead plants, and animal waste. By decomposing these materials, they help in reducing the volume of waste and preventing the accumulation of harmful substances, thus contributing to a healthier environment.
| 5. Can decomposers be harmful to humans? | |
Ans. While decomposers are generally beneficial for ecosystems, some decomposers can be harmful to humans. For example, certain types of bacteria and fungi can cause diseases or infections if they come into contact with open wounds or are ingested. However, proper hygiene practices and waste management systems help minimize the risks associated with harmful decomposers.
