Q: With reference to the food chains in ecosystems, which of the following kinds of organism is/are known as decompose organism/organisms?
- Virus
- Fungi
- Bacteria
Select the correct answer using the codes given below:
a) 1 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and 3
Correct Answer: Option (b)
- Most viruses need a living host organism-they are more like a parasite. Viruses reproduce by sticking their DNA into living cells and their DNA “takes over” the living cell and uses the living cells’ tools to replicate the virus’ DNA and make more viruses. Bacteria that are used in decomposition need the dead animals’ flesh for food. Hence, option (b) is correct.
