The organisms in this photograph would most likely produce oceanic sediments that are:
calcareous.
cosmogenous.
neritic.
lithogenous.
siliceous.

The photograph is missing in this question.

The correct answer is --- Calcareous

Explanation:

Calcareous means composing of partly or mostly of calcium carbonate. It means it contains lime or is chalky.

In oceans or sea floors,  calcareous sediments are deposited in a shallow water near the land surface, since marine organisms depositing carbonate needs to be land derived nutrients.

Hence the answer is -- calcareous.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !

i do believe   by (keeping an organized record of all sources he or she referenced)good luck.
