Where are coral reefs found?

• Polar waters

• temperate, mid-latitude waters

• tropical waters

• only near volcanos

Estuaries

• are always saltwater ecosystems

• are always freshwater ecosystems

• are ecosystems where both fresh water and salt water are present

• prevent the development of salt marshes

Estuaries are very productive ecosystems because they receive fresh nutrients from

• lakes and ponds

• rivers and oceans

• marshes and swamps

• streams and springs

What makes an estuary wildlife unique

• They are pretty

• They can handle different levels of salinity

• They grow to huge sizes

• They eat lots of freshwater organisms

Who is the secondary consumer?

• the plankton , because it gets eaten by the zooplankton

• zooplankton, because it eats the plankton then gets eaten by the small fish.

• small fish, because it eats the zoo plankton which ate the plankton.

• The shark, which ate he small fish.

Why can't phytoplankton survive hydrothermal vent?

• phytoplankton and other organismins harness sunlight , to create photosynthesis , near hydrothermal vent there is no sunlight

• Because of the heat from the hydrothermal vents , the phytoplankton wouldn't be able to survive

• It very hard to organisms to in the deep sea because of its extreme and harsh conditions
