Explanation

To determine which statement regarding the ethical argument for conserving biodiversity is incorrect, we can analyze each option step by step.

**Step 1: Analyze Statement A**
- Statement A claims, "We owe to millions of plant, animal, and microbe species with whom we share this planet."
- This statement is correct as it reflects the ethical perspective that humans have a responsibility to other species due to our shared existence on Earth.

**Step 2: Analyze Statement B**
- Statement B states, "Every species has an intrinsic value only when it is of an economic value to us."
- This statement is incorrect. The ethical argument for biodiversity conservation emphasizes that every species has intrinsic value regardless of its economic value. Therefore, this statement contradicts the ethical argument.

**Step 3: Analyze Statement C**
- Statement C states, "It is our moral duty to care for the well-being of all species i.e., our biological legacy."
- This statement is correct. It aligns with the ethical argument that emphasizes our responsibility to protect and conserve biodiversity for future generations.

**Step 4: Analyze Statement D**
- Statement D states, "All of these."
- Since we have identified Statement B as incorrect, Statement D cannot be correct.

**Conclusion:**
The incorrect statement regarding the ethical argument for conserving biodiversity is **(b) Every species has an intrinsic value only when it is of an economic value to us.**

**Final Answer: (b)**
