The correct Answer is:
### Step-by-Step Solution: **(i)** The first blank requires us to identify the organisms that help in the decomposition of plant and animal wastes. The process of decomposition is primarily carried out by microorganisms. The two main types of microorganisms involved in this process are: - **Bacteria**: These are single-celled organisms that break down organic matter. - **Fungi**: These organisms also play a crucial role in breaking down complex organic materials. So, the correct answer for the first blank is "Bacteria" and "Fungi". **(ii)** The second blank asks for a term that describes the condition when too much water accumulates around the roots of plants. This situation is detrimental to plant health as it can lead to root suffocation due to lack of oxygen. The term used to describe this condition is: - **Waterlogging**: This occurs when water saturates the soil and fills the spaces between soil particles, preventing air from reaching the roots. Thus, the correct answer for the second blank is "Waterlogging". **(iii)** The third blank requires us to identify a simple agricultural tool used for removing weeds and ploughing the soil. The tool that fits this description is: - **Hoe**: A hoe is a hand tool used in gardening and agriculture for digging, cultivating, and weeding. Therefore, the correct answer for the third blank is "Hoe". ### Final Answers: (i) Bacteria and Fungi (ii) Waterlogging (iii) Hoe
