Question

A chemist is studying dissolved gases in the ocean. She graphs her data as shown below. Explain the trend shown in dissolved oxygen and carbon dioxide versus depth, and then predict where organisms that rely on high oxygen concentrations would live. Justify your answer by using the data provided.

Answer 1

What grade you in ????? Bc that’s hard

Answer 2

Answer:

Don't copy word for word, but here are the explanations for the two parts of this question.

Explanation:

1. Explain the trend shown in dissolved oxygen and carbon dioxide versus depth

~ Looking at the chart you can see that there is a higher concentration of O2 in the higher depths of the ocean. Its concentration is around 6 ml/l when the depth is around 0 ft. The chart showing the depth getting deeper - to around 8,000 ft, O2 concentration is around 2 ml/l. Which concludes that the higher you are in the ocean, the higher the concentration of oxygen there is. The opposite conclusion applies for CO2. For example 8,000 ft of depth causes the level of CO2 to rise to 4.4 ml/l. At a depth of 2,000 ft carbon dioxide levels are about 2.8 ml/l. This data tells us that carbon dioxide levels rise the deeper you go into the ocean.

2. Predict where organisms that rely on high oxygen concentrations would live

~ Organisms that rely on high oxygen concentration would live in higher depths of the ocean. The epipelagic and mesopalegic zones have a higher concentration in oxygen than bathypelagic or abyssopelagic zones, so the epipelagic and mesopalegic zones would be good for organisms that need a higher concentration of oxygen to survive. Light is also much closer to the water in the higher zones making it a better habitat for those specific organisms. Organisms that rely on high oxygen also rely on photosynthesis.
