Which are stronger pound for pound Herbivores or Carnivores?

[parvez]

I have been wondering, which are more muscular or stronger pound for pound generally, herbivores or carnivores? In my view herbivores must be stronger because of the following reason.

The energy obtained by all living organisms on the earth is from sun. The energy from the sun is taken up by plants, photosynthesis occurs and energy is produced. Not all energy is utilized by plants. Some of it is wasted as heat. So, plants are the biggest living things probably on this planet as they utilize maximum energy from sun. Similarly, herbivores which consume plants utilize it for energy production. Even here some of the energy is wasted during the process. So, they must be the second biggest living organisms on the earth. Carnivores feed on herbivores even here some of energy is wasted. So, the amount of energy available for herbivores is not available for carnivores. So, I feel herbivores must be more stronger even pound for pound i suppose. Please state your opinions on this. Reply
