Question

Which of the following statements best describes the carbon atoms present in grass-eating cows?

		The carbon atoms came from the soil and were incorporated into sugars in the grass.
		Inorganic carbon atoms in the grass were incorporated into organic molecules by the cow.
		The carbon atoms came from the cow’s mother, which were synthesized from ATP.
		The carbon atoms came from carbon dioxide and were incorporated into sugars through photosynthesis in the grass.

Answer 1

D). Comes from CO2 and gets incorporated into sugars manufacturered by Green plants.

Now let's see :

Come to photosynthesis::--

In this reaction CO2 and water as well as photons from sun rays and then process results into Sugar production called photosynthesis.

6CO2+12H2O+Sun light~~~~ C6H12O6+6O2+6H20

Now above reaction CO2(Carbon content) reduces into glucose and then this grass eaten by Cattels so they get Carbon (glucose) from grass and and Grass where does it get grass from??

Ofcourse from CO2 in environment. Okay that's it
