A continuous process is set up for treatment of wastewater. Each day, 10⁵ kg cellulose and 10³ kg bacteria enter in the feed stream, while 10⁴ kg cellulose and 1.5 x 10⁴ kg bacteria leave in the effluent. The rate of cellulose digestion by the bacteria is 7 x 10⁴ kg d^-1. The rate of bacterial growth is 2 x 10⁴ kg d^-1 ; the rate of cell death by lysis is 5 x 10² kg d^-1. Write balances for cellulose and bacteria in the system.

The larvae of some insects are merely small versions of the adult, whereas the larvae of other insects look completely different from adults, eat different foods, and may live in different habitats. Which of the following most directly favors the evolution of the latter, more radical, kind of metamorphosis?
