Which of the following statements is incorrect regarding the overgrowth of algae?
a. The algae are heterotrophs.
b. The nitrogen in the fertilizer is in the ammonium form, the preferred nitrogen source of most microbes.
c. The phosphorus in the fertilizer is in the phosphate form, the preferred phosphorus source of most microbes.

Answer:

A. The algae are heterotrophs

Explanation:

Algae which are heterotrophic obtain nutrients from complex organic substances. Thus, this type of algae is a consumer. This is in contrast to autotrophs, which form their own organic substances from simple inorganic substances. They produce their own energy

The diammonium phosphate which run off until the lake nourish these algae and make them grow without limit.

Answer:

The incorrect answer is the letter a. The algae are heterotrophs

Explanation:

Algae are characterized by being single-celled or multicellular eukaryotic organisms that, for the most part, have a cell wall formed of cellulose and some other substance such as agar, carrageenan, calcium carbonate, etc. In addition, algae are autotrophic, that is, they are capable of photosynthesis and synthesize organic molecules (food) from inorganic substances and sunlight energy.
