Terrestrial and Aquatic Biomes 1.2-1.3

Question 1

Biomes

Answer 1

Large regions of the earth that are characterized by climate conditions

Question 2

Terrestrial Biomes are defined by annual _____ and _____

Answer 2

Temperatures and precipitation

Question 3

How much salt there is in a body of water determines which species can survive and usability for drinking

Answer 3

Salinity

Question 4

Determines which plants and organisms can survive, how much O2 can dissolve into H2O

Answer 4

Flow

Question 5

Warmer water holds less dissolved O2 so it can support fewer aquatic organisms

Answer 5

Temperature

Question 6

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

Answer 6

Depth

Question 7

Have high O2 due to flowing mixing H2O and air, also carry nutrients rich sediments

Answer 7

Rivers

Question 8

Standing bodies of fresh H2O

Answer 8

Lake

Question 9

Shallow water with emergent plants

Answer 9

Littoral

Question 10

Where light can reach (no rooted plants)

Answer 10

Limnetic

Question 11

Too deep for sunlight (No photosynthesis)

Answer 11

Profundal

Question 12

Murky bottom were bugs live, nutrient rich sediments

Answer 12

Benthic

Question 13

Area with soil submerge saturated in water for at least part of the year, but shallow enough for emergent plants. Plants living here have to be adapted to living with roots submerged in standing water

Answer 13

Wetland

Question 14

Benefits of wetland

Answer 14

1. Stores excess water during storms, lessening floods
2. Recharges groundwater by absorbing rainfall in to soil
3. Roots of wetland plants filter pollutants from water draining through
4. Highly plant growth due to lots of water and nutrients

Question 15

Area where rivers empty into the ocean. Mix of fresh and saltwater. High productivity

Answer 15

Estuaries

Question 16

Estuary habitat along coast and temperature climate. Breeding ground for many fish and shellfish species

Answer 16

Salt marsh

Question 17

Estuary habitat along coast of tropical climates.

Answer 17

Mangrove swamps

Question 18

Narrow band of coastline between high and low tides. Organisms must be adapted to survive crashing waves and direct sunlight and heat during low tide

Answer 18

Intertidal zones

Question 19

Warm shallow waters beyond the shoreline. Most diverse marine biome on earth. Mutual relationships Between coral and algae.

Answer 19

Coral reefs

Question 20

Low productivity area as only phytoplankton can survive in most of the ocean.
Photic zone = Area where is sunlight can reach
Aphotic zone = Area too deep for sunlight

Answer 20

Open ocean
