If an enzyme is placed in a lower than optimal pH, its loss of activity might be due to

denaturing of the peptide bonds

Explanation:

Enzymes are proteins that help speed up chemical reactions. However, they require specific temperatures and pH's to work optimally and produce the best outcome.

If an enzyme is placed in a lower than optimal pH, that means that there are more H+ ions, and the environment is more acidic. This influx of H+ ions can denature the peptide bonds within the enzyme, causing it to fold in a different way and be unable to carry out its normal duties. Hence, the activity of the enzyme will decrease significantly.

Tropical rain forests such as the Amazon are great for coconuts. They adapt in the warmth and dampth. The humid and hot weather makes coconuts the perfect home for them, just like the sea and oceans are the perfect place for fishes.
