Answer;
Fertilizers contain nutrients, especially phosphorous and nitrogen, according to the Natural Resources Defense Council. Since fertilizers help plants grow, they also cause algal blooms in aquatic ecosystems.
Explanation;
Fertilizers are commonly used substances that aid in the growth of many different fruit and vegetable species. Unfortunately, these substances are often toxic, or create undesirable organic reactions.
Fertilizers reach marine ecosystems through runoff. When it rains, the growth aids in the soil drift. These substances eventually make their way into rivers and streams. From there, they flow through the water and are eventually carried to the ocean.
Chemicals in fertilizers can runoff and hurt/kill organisms that are living in aquatic ecosystems.
