Answer: C) phosphate and nitrogen pollution

Explanation:

Eutrophication is a phenomena in which the water body which consists of high concentration of fertilizers drained in a water body by agricultural field runoff. The fertilizers typically composed of phosphates and nitrogen results in growth of aquatic plants and extensive algal growth on the surface of water. This leads to the depletion of oxygen levels in the water body. As a result of this the water exhibit a foul smell and the aquatic animals decline in numbers.

According to the given situation, the large amount of algae in a lake is because of the increase in the phosphate and nitrogen pollution. The increase in concentration of the phosphate and nitrogen will lead to the phenomena of eutrophication.

___ is a quantitative increase in the size of a certain anatomical structure.
Ivahew [28]

Height and weight are quantitative increase in the size of a certain anatomical structure.

<h3>What is Weight?</h3>

The gravitational force acting on the object, expressed as weight as a vector quantity. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others define it as the strength of the force applied to a body by systems that work to counteract the effects of gravity. For example, a spring scale measures weight. As a result, the weight would be zero during free fall.

Terrestrial objects are capable of having no weight in this sense. For example, if we disregard air resistance, the famous apple falling from the tree and hitting the ground near Isaac Newton would have no weight.
