Which zone of an aquatic ecosystem tends to have more life—both producers and consumers?

• aphotic zone
• photic zone
• benthic zone
• All have roughly the same amounts of life.

Which ecosystems are considered standing freshwater ecosystems?

• lakes
• wetlands
• ponds
• all of the above

Ecologists use similarities between ecosystems to classify them into broad categories called

• biomes.
• littoral zones.
• estuaries.
• benthic zones.

• tropical rain forest
• temperate grassland
• coral reef
• desert

Criteria such as salinity, depth, and whether the water is flowing or standing are used by scientists to

• classify aquatic ecosystems.
• measure net primary productivity in lakes.
• distinguish aquatic ecosystems from terrestrial ecosystems.
• determine the number of species in a body of water.

• It has deep water.
• It is far from the shore.
• It is rich in invertebrates , and other organisms.
