APES FINAL

gross primary productivity

The total rate of photosynthesis in a given area.

tropical rain forest

the terrestrial biome with the highest net primary productivity

net primary productivity

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

freshwater wetlands

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.

coral reefs

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

rivers

This freshwater biome is characterized by fast-flowing water that can originate from underground springs or runoff, which carries sediment and organic material.

primary productivity

This rate of reaction can be measured in the dark by determining the amount of oxygen gas consumed in a period of time.
