Which of the following is not a cost associated with the use of natural resources? a. environmental b. energy c. renewable d. economic

Option C, Renewable

Explanation:

Renewable is a term that defines the type of energy which exist in enormous amount and can be used again and again. Thus it can not be a term which can be linked with cost of using a natural resource.  

However, when a natural source such as petroleum is used , it directly or indirectly affect the environmental, energy or economic cost.

Hence, option C is the correct answer.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
