Grazing rabbits and sheep: This is a continuation of Exercise 13. In addition to the kangaroos, the major grazing mammals of Australia include merino sheep and rabbits. For sheep the functional response is

Here S and H are the daily intake (measured in pounds), and V is the vegetation biomass (measured in pounds per acre).

a. Find the satiation level for sheep and that for rabbits.

b. One concern in the management of rangelands is whether the various species of grazing animals are forced to compete for food. It is thought that competition will not be a problem if the vegetation biomass level provides at least 90% of the satiation level for each species. What biomass level guarantees that competition between sheep and rabbits will not be a problem?
