Unit 1 Aquatic Biomes

Question 1

Salinity

Answer 1

Salt determines which species can survive and usability for drinking

Question 2

Depth

Answer 2

Influences how much sunlight can penetrate and reach plant below the surface for photosynthesis

Question 3

Flow

Answer 3

Determines how much co2 can dissolve into water and which plants/animals can survive

Question 4

Temp

Answer 4

Warmer water holds less dissolved co2 so it can support fewer aq orgs

Question 5

Estuaries

Answer 5

Where atm and ocean meet salt and freshwater mix

Question 6

Types of estuaries

Answer 6

Temperate estuaries - characterized by salt tolerant grasses

Tropical estuaries - characterized by salt tolerant trees

Question 7

Littoral zone

Answer 7

Shallow area of soil and water ( lots of photosynthesis)

Question 8

Limnetic zone

Answer 8

Deeper - only algae exists and extends as deep as sunlight penetrates

Question 9

Profundal zone

Answer 9

Deepest zone - no producers limited o2

Question 10

Benthic zone

Answer 10

Lake bottom

Question 11

Oligotrohpic

Answer 11

Lakes with low pp due to limiting nutrients such as n and p

Question 12

Mesotrohic

Answer 12

Lakes with moderate levels of pp

Question 13

Eutrophic

Answer 13

High pp
