The rabbit and the owl both ate 10 pounds of food in a week. Which organism gains more energy from eating 10 pounds of food?Explain.

## Step 1: This question requires an understanding of the energy flow in an ecosystem, specifically the concept of the energy pyramid or the Ten percent Law. This law states that only ten percent of the energy from one trophic level is transferred to the next level. ## Step 2: In an energy pyramid, the different levels represent different groups of organisms that might constitute a food chain. From the bottom-up, they are: Producers (like plants), Primary Consumers (like rabbits), and Secondary or Tertiary Consumers (like owls). ## Step 3: The rabbit, being a primary consumer, would obtain its energy directly from the producers (plants). On the other hand, the owl, being a secondary or tertiary consumer, would obtain its energy from the primary consumers (like mice or rabbits) or other secondary consumers. ## Step 4: Given that the energy decreases as one moves up the trophic levels, the rabbit would gain more energy from eating 10 pounds of food than the owl. This is because the rabbit is at a lower trophic level than the owl, and thus, less energy is lost in the transfer from the food to the rabbit.### The formula to calculate the energy transfer is: ###
