How mechanism can be classified as non-equilibrium mechanism | Homework Help

1. In the region where both species co-occur the northern snuffle has a relatively wide and short snuffle whereas the southern snuffle has a long and relatively thin snuffle. In areas where they occur alone the morphology of their snuffle is fairly similar. This observation demonstrates what?

a. The competitive exclusion principle

b. Character displacement

c. Un-stable coexistence

d. Competitive release

e. Mechanism of coexistence

2. The researchers have determined that the mechanism allowing the coexistence of the two species is resource partitioning, with the axis of environmental heterogeneity being gradient in food types: grasses and tree leaves and the trade-off being that the southern snuffle is a more efficient forager on tree leaves due to its long and thin snuffle while the northern snuffle is a more efficient forager on grasses due to its short and thick snuffle. Based on all you know about the Ecology of the two species, this mechanism can be classified as a non-equilibrium mechanism of coexistence.
