A scientist is wondering why a certain region in the ocean doesn't have maximum phytoplankton growth, despite having plenty of nutrients. The scientist samples the water for nutrient levels and finds that there is 2.5 ug/L of Phosphorus and 27ug/L of Nitrogen. What can be said about the water?
A) The water is nitrogen limited
B) The water is phosphorus limited
C) The water has an adequate nitrogen and phosphorus, so it is likely iron limited
D) The water has adequate nutrients, but is likely limited by light availability

C The water had adequate nitrogen and phosphorus, so it is likely iron limited.

Explanation:

Phytoplankton are single- cell organisms that live in oceans.

They require nitrogen, phosphorus and trace amount of iron to survive.

From the scientist's results after testing the water for nitrogen and phosphorus,there are reasonable amount of these elements.

Therefore insufficient iron in the water is the reason why he could find plenty phytoplankton in the ocean.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
