the planet’s biodiversity is not affected
the biodiversity of the planet decreases
the planet’s biodiversity cannot be measured

biological remediation
biological augmentation
biological magnification
biological eutrophication
Ladybugs being introduced into an ecosystem to control the aphid population is an example of

bioremediation
native species
biological augmentation
What role do trees play in preventing flooding?
trees give off carbon dioxide
the stems of trees store food
the roots keep soil in place and pull in water
