A dilute solution has less amount of solute in the solvent. Therefore, the correct answer to the question is option B.
Explanation:
A solution is defined as a mixture of the solute and solvent. The concentration of solution depends upon the solute as well as solvent. A solution is known as to be dilute when there is less amount of solute and more amount of solvent.
A solution is said to be consulted when there is more amount of solute and less amount of solvent. Therefore, we can see that concentration of the solution is dependent upon the solute amount. In a solution a solute is present in in little less amount as compared with the solvent.
The answer would be C. Energy is used through the food chain so energy always decreases. Population size would commonly decrease according to the pyramid of food chain but since there's no answer for that, C would be the most suitable
