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?
