Ocean Aquatic Biome Bellwarmers, notes, study guides Quiz

Salinity refers to

• how many plants are in the water

• how many organisms live in the water

• how much salt in is water

Most of the water on Earth is located in the oceans and has a salinity of about 3.5%. Which statement best explains why rain is fresh water and has a very low salinity?

• When water precipitates from oceans, most of the salt remains in the oceans.

• When water evaporates from oceans, most of the salt remains in the oceans.

• When water precipitates from clouds, most of the salt remains in the clouds.

• When water evaporates from clouds, most of the salt remains in the clouds.

Where is most of Earth’s water located?

• glaciers

• lakes

• oceans

• rivers

Which of these is NOT a marine biome?

• open ocean
• deep ocean floor
• seashore
• wetlands

In which biome do these plants (seagrass) survive?

• wetland

• ocean

• freshwater

• Well

What is the largest ocean of the marine biomes?

• Southern ocean

• Pacific ocean

• Arctic ocean

• Indian ocean

• Atlantic ocean

Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that influence life forms vary with location in the ocean. Oceanographers divide the ocean into five broad vertical zones as seen in the chart. Compare the abiotic characteristics of the five ocean zones. Which of these conclusions about life forms found in the zones is supported by the information in the chart?

• The mesopelagic zone hosts a diverse zooplankton community instead of a phytoplankton or algae community and virtually no fish species..

• The epipelagic zone is the only zone of the five zones where visible light and algae can be found

• Because there is no light in the abyssal zone, organisms feed on each other or the dead organic material, detritus, that falls into the abyssal zone from above.

• .Because of the severe abiotic conditions, there are no life forms found in the hadalpelagic zone.

What plant and its adaptation would be LEAST adapted for survival in an estuary ocean biome?

• rush grass with dense fibrous roots that anchor it in thick mud

• mangrove trees with large aerial roots

• eel grass which survives submerged in saltwater

• hosta lilies with large leaves to collect light in shade
