A short food chain is shown above. Calculate how much energy (in kcal) is needed to support the growth of a single wolf for a year. Here are some facts and assumptions that you will need to do this calculation.
 

• A wolf puts only about 2 percent of its total yearly intake in kilocalories into producing new growth. This amounts to about 8 kilograms of new tissue per year (average for young and old wolves), which is equivalent to 10,000 kcal per year.
• Deer put only about 1 percent of their total yearly intake in kilocalories into producing new growth.
• Plants put only about 0.5 percent of the sun's energy to which they are exposed into producing new growth.
• Assume that all of the intake for the wolf comes from deer (even though you know, having seen the movie Never Cry Wolf, that wolves eat a lot of mice).
