First paragraph:
Trophic budgets reveal the efficiency with which an animal extracts its requirements from the environment. For a student, their construction is an excellent way of developing laboratory skills, a facility for computation, and an understanding of the fundamentals of ecology. However, they need not be an end point in themselves because they have many applications in applied and basic ecology.
