Unit 1 Progress Check: MCQ

A temperate grassland biome has a gross primary productivity of 3,480kilocalories/meter2/year3,480kilocalories/meter2/year and a net primary productivity of 2,000kilocalories/meter2/year2,000kilocalories/meter2/year. Which of the following is the approximate number of kilocalories/meter2/yearkilocalories/meter2/year available to herbivores in that biome?

200kilocalories/meter2/year

The total rate of photosynthesis in a given area.

Gross primary productivity

This biome contains a nutrient-rich environment created by falling leaves and trapped organic materials from the large trees, and it provides the ecosystem service of filtering pollutants from water.

B Freshwater wetlands

This biome is found in shallow waters off the coastline and is Earth's most biologically diverse marine biome.

Coral Reefs

The energy available to consumers determined by subtracting the energy used by plants from the total energy transformed by the process of photosynthesis.
