Answer:  animal waste; fertilizers

Explanation:

The bacteria are small prokaryotic organisms. A large colony of small bacteria can be found in water, air and soil. Some bacteria also grow in the digestive tract of humans and animals. The fecal discharge of animals will contain the bacteria colonies which will contaminate the pond water when drains along with the surface runoff. The nitrogen is element that is required by the plants for their appropriate growth. Usually the soils of the agriculture land lacks nitrogen. The nitrogen in the soils are added up by the fertilizers. The surface runoff will take away the fertilizers and will deposit them to the pond water. This will lead to the contamination of pond water with nitrogen.

There are basically three types of evolution divergent, convergent and parallel evolution.

a) Divergent Evolution – As the name depicts the species in this form of evolution becomes divergent i.e they evolve to become different from each other. This form of evolution is responsible for the current diversity of organisms existing on planet earth. For example human and apes evolved from a common primate ancestor.
