NPP, Latitude and Photosynthesis

Question 1

What does net primary productivity describe?

Answer 1

The amount of organic material generated in a biome through the process of photosynthesis

Question 2

What is biomass?

Answer 2

The total weight of living organisms in an area

Question 3

What is the equation for net primary productivity?

Answer 3

Gross primary productivity - Respiration Rate

Question 4

What is the equation for gross primary productivity?

Answer 4

Net primary productivity + Respiration Rate

Question 5

What is gross primary productivity?

Answer 5

The rate at which carbon is captured and stored in living organisms

Question 6

What are the units that GPP and NPP are measured in?

Answer 6

Grams of carbon per metres squared per year

Question 7

What is photosynthesis?

Answer 7

The process of converting sunlight and raw material into simple sugars

Question 8

What is cellular respiration?

Answer 8

The process of breaking sugar into the cell to release energy

Question 9

What is the equation for photosynthesis?

Answer 9

6CO2 +6H2O + Energy = C6H12O6 + 6O2

Carbon Dioxide, Water and Energy = Glucose and Oxygen

Question 10

What is the equation for cellular respiration?

Answer 10

C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy

Glucose and Oxygen = Carbon Dioxide, Water and Energy

Question 11

What is a terrestrial biome?

Answer 11

An area of land with similar climate that includes similar communities of plants and animals

Question 12

What is the absolute location?

Answer 12

The exact latitudes and longitudes of a certain location

Question 13

What is the relative location?

Answer 13

The location of a place in relation to another

Question 14

What is respiration?

Answer 14

The reverse reaction of photosynthesis, which occurs when it is dark

Question 15

What are the SHEEPT factors that can influence net primary productivity?

Answer 15

Social, Historical, Environmental, Economic, Political and Technological

Question 16

What is the correlation between NPP and latitude?

Answer 16

The abundance of sunlight and adequate nutrient levels changes based on the latitude of a certain biome, affecting the total amount of NPP able to be produced

Question 17

What is solar insolation?

Answer 17

The amount of electromagnetic energy or solar radiation incident on the surface of the earth, basically the amount of sunlight shining on us

Question 18

In each hemisphere, what are the three cells in which air circulates through the entire depth of the troposphere?

Answer 18

Hadley, Ferrel and Polar

Question 19

What is an autotroph?

Answer 19

A life form that makes its own food from sunlight or chemical compounds, such as grass, plants or trees

Question 20

What is a Ferrel cell?

Answer 20

The motion of air in the mid-latitudes, characterised by sinking air near 30 degrees and rising air towards the poles

Question 21

What is a Hadley cell?

Answer 21

A tropical atmospheric circulation which features rising air near the equator

Question 22

What is a Polar cell?

Answer 22

The smallest and weakest cell, which extends between 60 and 70 degrees north and south to the poles
