1. Write a hypothesis describing what you believe may be causing the heavy growth of algae in the
pond. Base your hypothesis on your observations
of the two ponds.

The hypothesis is ''the higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''

Explanation:

''The higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''. The population of algae increases vigorously when there is high concentration of nutrients such as nitrogen and phosphorus in the pond. So if there are two ponds having different concentration of nutrients so the population of algae will be higher in that pond where nutrients are present in high amount.

the cell theory states that all living things including animals, as well as plants, are made of cells.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
