Use and value diversity

The teeming zillions.Two species of shrimp-like copepods, 1 to 2 mm long, are perfectly adapted to life in a rainwater pool along with other microfauna. Although closely related they all thrive together because each combs the water for different types of algae. Freshwater copepods reduce mosquito breeding through greater efficiency in harvesting the same foods, while marine copepods sequester carbon to the ocean floor on a monumental scale.
