Biology 1 Lecture Thanksgiving - Primary Productivity and Biomes Part 2

Temperature, precipitation, sunlight, wind

Name 4 features of weather (atmospheric conditions)

Solar orbit, tilt

What are seasons at high latitude driven by?

Different biomes

What is the result of variation in temperature and precipitation?

Average annual temperature/precipitation, annual variation in temperature/precipitation

List 2 main drivers of biomes

Temperature, moisture

_______________ and _____________ influence net primary productivity (NPP)

Warm and wet conditions

On land/terrestrial ecosystems, what maximizes photosynthesis and plant growth?

There is not enough light of the right wavelength, optimal absorption chlorophyll doesn't transmit well through water

CASE: Why is primary productivity low in deep water?

Both A and B

CASE: Which is true about the NPP per unit area for the following biomes?
A) Coral reefs and algal beds > open ocean
B) Tropical wet forest > temperate deciduous forest
C) Both A and B
D) Neither A or B

B

CASE: Which is true about the area covered for the following biomes?
A) Coral reefs and algal beds > open ocean
B) Tropical wet forest > temperate deciduous forest
C) Both A and B
D) Neither A or B

B, tropical wet forest > temperate deciduous forest

CASE: Which is true about total primary productivity (same as GPP)
A) Coral reefs and algal beds > open ocean
B) Tropical wet forest > temperate deciduous forest
C) Both A and B
D) Neither A or B

Tropical wet forest, open ocean

What are the greatest contributors to the world's primary productivity?
