The three options that can cause the amount of dissolved oxygen to decrease are:

1. **Excess nutrients lead to an algae bloom on the surface of the water** - This can reduce light penetration and block sunlight from reaching aquatic plants, affecting their ability to photosynthesize.

2. **The water temperature increases, decreasing the solubility of the oxygen gas** - Warmer water holds less dissolved oxygen, which can lead to lower levels of oxygen in the water.

3. **Aquatic plants die and stop photosynthesizing** - When plants die, they cease to produce oxygen through photosynthesis, contributing to a decrease in dissolved oxygen levels.

Thus, the correct selections are the first, third, and fourth options.
