Read the given passage carefully.
The organisms P and Q occur on the forest floor. They convert the dead organic waste generated in forest into simpler substances which can be then reused by organisms R for their growth and development, Identify P, Q and R and select the correct statement.

Options

A. P and Q could be bacteria and fungi respectively whereas R could be plants.
B. P and Q could be bacteria and plants respectively whereas R could be fungi.
C. P and Q could be plants and animals respectively whereas R could be bacteria.
D. P and Q could be herbivores whereas R could be a detritivore.

Explanation

To solve the question, we need to identify the organisms P, Q, and R based on their roles in the ecosystem as described in the passage. Here's a step-by-step breakdown of the solution:

### Step 1: Understand the Roles of Organisms
The passage states that organisms P and Q convert dead organic waste into simpler substances. This process is crucial for recycling nutrients in the ecosystem.

**Hint:** Think about which organisms are responsible for breaking down dead matter in an ecosystem.

### Step 2: Identify P and Q
The organisms that convert dead organic waste into simpler substances are known as decomposers. Common examples of decomposers include fungi and bacteria.

**Hint:** Recall the types of organisms that feed on dead and decaying matter.

### Step 3: Identify R
The passage mentions that the simpler substances produced by P and Q can be reused by organism R for growth and development. Typically, plants utilize these nutrients to grow, as they are primary producers in the ecosystem.

**Hint:** Consider which organisms benefit from the nutrients released by decomposers.

### Step 4: Conclude the Identifications
- Organism P: Fungi (a type of decomposer)
- Organism Q: Bacteria (another type of decomposer)
- Organism R: Plants (which use the nutrients released by decomposers)

**Hint:** Think about the relationship between decomposers and primary producers in an ecosystem.

### Step 5: Select the Correct Statement
Based on the identifications:
- P and Q are fungi and bacteria respectively.
- R is plants.

The correct statement would be that P and Q could be bacteria and fungi respectively, where R could be plants.

**Final Answer:**
- P = Fungi
- Q = Bacteria
- R = Plants

The correct statement is: "P and Q could be bacteria and fungi respectively, where R could be plants."
