Where did it go…A squirrel eats an acorn full of chemical energy. However only 10% of that energy is passed along to that squirrel. We know that energy cannot be created or destroyed. So, where did the other 90% of the chemical energy go.

Scientists measured the average weight of living things found in a certain field. They found on average: 9,600 grams of plant life, 1,100 g of herbivorous animals, and 400g of carnivorous animals per square meter in the field. Why is the total weight of carnivores only about 4% of the amount of the plants in the same area?
