Answer: Fertilizers and pesticides contribute to runoff that goes into the water, causing habitat degradation.
Explanation:
Fertilizers and pesticides are the chemical formulations which are added to the agricultural field so as to enhance the growth of the crops and raising their yield. The runoff is the water erosion. In runoff water from any source such as rainwater, water from the snow melt and water from the river stream flows over the surface of soil. It remains unabsorbed within the soil. Such water flows with an appropriate speed and mixes with the water reservoir.
Thus according to the given situation, the fertilizers and pesticides along with the water runoff will be added to the water reservoir. As a result of this the increase in abundance of chemicals in the water source can make the water habitat unfit for the survival of aquatic animals due to contamination.
You have to put a lid on petri dishes in order to ensure that no outside contaminants get inside the dish.

The diaphragm,
During inhalation, the diaphragm is contracted which increases the volume of the lung cavity. During exhalation, the diaphragm is relaxed which decreases the volume of the lung cavity
