Answer:
potassium, nitrogen and phosphorous cycle
Explanation:
A fertilizer is a substance which is applied on the plants by farmers to increase the supply of nutrients for the plants. Fertilizers have known to be toxic in many ways such as they alter the potassium, nitrogen and phosphorus cycles. Nitrogen, potassium and phosphorus are present in abundant amounts in the fertilizers. Draining of these fertilizers into rivers and ponds is toxic for the aquatic life. Hence, the use of fertilizers disrupts the natural cycles and is toxic for many aquatic plants and animals.

Answer:
Group B
Explanation:
<u>The fish in group B are those in the control group.</u>
<em>A control group during an experiment represents a group of the subject that is subjected to all experimental variables except the independent variable - the manipulate-able variable that is supplied by the experimenter which directly affects the dependent variable. </em>
In this case, the independent variable is the type of food given to the two groups of fishes - microwaved or regular food while the dependent variable is the time it takes for the fishes to swim through the maze. Since the focus of the experiment is to see if microwaved food enhances the swimming speed of fishes, the group of fish that receives microwaved food would represent the treatment group while those that received regular food would be the control group.
Hence, group B represents the control group.
