Nirates and phosphates are important chemicals to living things. Explain why these chemicals can also be pollutants.

Nitrogen and phosphorus are essential elements for all living organisms. They are used in DNA and chemical processes in the body. Most nitrogen is found in the air and most phosphorus is bound up in rocks and sediments, making them unavailable to organisms. And they are pollutants cuz nitrogen and phosphorus support the growth of algae and aquatic plants, which provide food and habitat for fish, shellfish, and smaller organisms that live in water. But when too much nitrogen and phosphorus enter the environment - usually from a wide range of human activities - the air and water can become polluted

Explanation:

if my answer help, I hope you get better <3

Explanation:

When nitrate and phosphate ions concentrations in shallow waterbodies are in excess, there is overgrowth of water plants leading to the formation of algal bloom. This causes a high consumption of dissolved oxygen in the water. ... The dead plants and animals decay creating deterioration of water quality.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
