What is aim of expelling of uric acid through gut in insects?

Explanation

### Step-by-Step Solution:

1. **Understanding Excretory Products**: Insects excrete waste in the form of uric acid, which is different from mammals that excrete urea and aquatic animals that excrete ammonia.

2. **Toxicity of Uric Acid**: Uric acid is less toxic compared to urea and ammonia. This reduced toxicity makes it a safer option for excretion in insects, allowing them to avoid the harmful effects of more toxic waste products.

3. **Physical State of Uric Acid**: Uric acid is excreted as a solid, which means it does not require water for excretion. This is beneficial for insects, especially those living in arid environments where water conservation is crucial.
