Match the names of organisms given under column I with the ecological names given under column II , choose the answer which gives the correct combination of the alphabets of the two columns
Column I Column II
(A) Grass (p) Decomposer
(B) Grasshopper (q) Secondary carnivore
(C) Frog (r ) Producer
(D) Hawk (s) Primary consumer
(t) Primary carnivore

Options

A. A-r,B-t,C-s,D-q
B. A-r,B-s,C-t,D-q
C. A-r,B-p,C-t,D-s
D. A-p,B-r,C-s,D-t

Answer

To solve the matching question, we need to identify the ecological roles of the organisms listed in Column I and match them with the appropriate terms in Column II.

### Step-by-Step Solution:

1. **Identify the Organisms in Column I:**
- (A) Grass
- (B) Grasshopper
- (C) Frog
- (D) Hawk

2. **Understand the Ecological Roles:**
- **Grass**: This is a plant and is classified as a **Producer** because it produces energy through photosynthesis.
- **Grasshopper**: This organism feeds on grass (the producer) and is classified as a **Primary Consumer** because it consumes producers.
- **Frog**: This organism feeds on grasshoppers (the primary consumer) and is classified as a **Primary Carnivore** because it consumes other animals.
- **Hawk**: This organism feeds on frogs (the primary carnivore) and is classified as a **Secondary Carnivore** because it is at the next trophic level above the primary carnivore.

3. **Match the Organisms with Ecological Names:**
- (A) Grass → (r) Producer
- (B) Grasshopper → (s) Primary Consumer
- (C) Frog → (t) Primary Carnivore
- (D) Hawk → (q) Secondary Carnivore

4. **Write the Final Matches:**
- A (Grass) → r (Producer)
- B (Grasshopper) → s (Primary Consumer)
- C (Frog) → t (Primary Carnivore)
- D (Hawk) → q (Secondary Carnivore)

5. **Select the Correct Option:**
Based on the matches, the correct combination is:
- A → r
- B → s
- C → t
- D → q

Thus, the answer is option 2: A → r, B → s, C → t, D → q.
