The correct statement about the cause of algal blooms is: "Algal blooms are sometimes a natural occurrence and sometimes the result of human activities."

Here's why:

1. Algal blooms are not caused by fish. While fish can contribute to the nutrient load in a body of water, they are not the primary cause of algal blooms.

2. Algal blooms do not only happen naturally. While it's true that certain conditions can naturally lead to algal blooms (such as warm water temperatures and high nutrient levels), human activities can also contribute to their occurrence.

3. Algal blooms are not always human-caused. As mentioned above, there are natural conditions that can lead to algal blooms. However, human activities such as agriculture runoff, urban runoff, and industrial waste discharge can increase the nutrient levels in a body of water, making it more susceptible to algal blooms.

4. Algal blooms are sometimes a natural occurrence and sometimes the result of human activities. This statement is true because it acknowledges both the natural and human-induced causes of algal blooms.
