Question

Which of these ecosystems accounts for the largest amount of Earth's net primary productivity? A) tundra B) savannaC) salt marsh D) open ocean E) tropical rain forest

Answer 1

The tropical rain forest accounts for the largest amount of Earth's net primary productivity. Tropical rain forests are extremely productive ecosystems, with high levels of sunlight, warmth, and precipitation year-round, which supports rapid plant growth. The dense vegetation in tropical rain forests stores large amounts of carbon and produces about 40% of the world's oxygen. Due to their high productivity, tropical rain forests are also home to a diverse range of plant and animal species.
