Question 1

Marine biomes

Answer 1

oceans, coral reefs, estuaries; high salinity

Question 1

Freshwater biomes

Answer 1

lakes, ponds, rivers, streams; low salinity

Question 2

Streams & Rivers

Answer 2

Streams stem from rivers, high oxygen content, freshwater fish, little aquatic plants, organic matter from terrestrial biome

Question 3

Lakes & Ponds

Answer 3

standing freshater, eutrophic (high productivity), mesotrophic (moderately productive), oligotrophic (least productive and low nutrients)

Question 4

Freshwater wetlands

Answer 4

most productive global biomes, submerged in water almost always, lots of nutrients, filter pollutants, prevent flooding, home for bird breeding.

Question 5

Salt Marshes

Answer 5

non-woody emergent vegetation, along coast of temperate climates, salt, extremely productive - carry nutrient-rich material to ocean.

Question 6

Mangrove Swamps

Answer 6

similar to wetlands, trees with dense roots submerged in water, prevent natural disaster effects, located in estuaries or salt water areas.

Question 7

Intertidal Zones

Answer 7

narrow bands of coastline between high and low tide, harsh conditions w/ low tide, small organisms: crustaceans, sponges, etc., constant change in salinity and sulight

Question 8

Coral Reefs

Answer 8

warm & shallow waters, relies on photosynthetic algae for food, most diverse marine biome, coral bleaching due to acidification / pH lowering

Question 9

Open Ocean

Answer 9

deep ocean water, sunlight does not penetrate, photic zone: sulight can penetrate, aphotic zone: photosynthesis no longer takes place, benthic zone: muddy bottom.
