Answer: A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. ... In the food chain, energy is transferred from one living organism through another in the form of food. In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass rightarrow→right arrow cow rightarrow→right arrow human. But what if you had lettuce on your hamburger? In that case, you're also part of a food chain that looks like this: lettuce rightarrow→right arrow human

Explanation:
Assuming that carbon dioxide acts as an ideal gas given the following conditions, using the ideal gas equation shown below
,
and since
,
rewriting and rearranging the prior equation to make the variable 
the subject, yields
,
where is the volume occupied by the gas, 
is the mass of the gas, 
is the gas constant, 
is the temperature in Kelvins, 
is the pressure exerted by the gas and 
is the molecular weight of the gas molecule.
Therefore, plugging the given values into the rearranged equation,
