Photorespiration poses threat to plants yet it occurs in angiosperms. Why?

Explanation

**Step-by-Step Solution:**

1. **Understanding Photorespiration:**
- Photorespiration is a metabolic process that occurs in plants, particularly in angiosperms (flowering plants). It is characterized by the consumption of oxygen and the release of carbon dioxide, which is opposite to the process of photosynthesis.

2. **Why is Photorespiration Considered Wasteful?**
- During photorespiration, energy molecules such as ATP and NADPH are consumed. This leads to a reduction in the overall efficiency of photosynthesis, making it a wasteful process for the plant. Essentially, the plant expends energy without producing useful sugars.
