Answer 2

a.) Over time, ant colonies find and use the shortest paths in their foraging. Here we have further evidence that when multiple paths (with differing path lengths) exist between node pairs in an ecological network, the shortest paths are more likely to be used.

Ant colonies solve the “shortest route” problem (also known as the Operations Research traveling salesman problem) when traveling to/from a food source.When foraging for food, an ant secretes a chemical substance called pheromone to mark its trail. Shorter routes are traveled in less time and get more pheromone deposited more quickly than in longer routes. Other ants prefer to travel a trail richer in pheromones, so the shorter routes get reinforced. This process eventually finds the shortest route, which most ants will then use. Following the same process, an ant colony will find the shortest route from the nest to each food source as well as the shortest route between food sources; that is, the ant colony solves the shortest route/traveling salesman problem.

b.) It prevents water accumulation.

This is the most important use of a good drainage system; it allows the free flow of water and in most cases prevents accumulation that can lead to flooding. Drainage systems also prevent the accumulation of stagnant water, which can encourage mosquitoes to breed.
