It is also easy to overlook the services that ecosystems provide humanity. They enrich the soil and create the very air we breat

The life-sustaining matrix is built of green plants with legions of microorganisms and mostly small, obscure animals—in other words, weeds and bugs. Such organisms support the world with efficiency because they are so diverse, allowing them to divide labor and swarm over every square meter of the earth’s surface.

C. restating his claim.
D. using deductive reasoning.
