4.1 Study Guide

Question 1

Biomass

Answer 1

The amount there is of a certain species in a certain area.

Question 2

Productivity

Answer 2

The rate at which a species grows it’s population.

Question 3

Efficiency

Answer 3

How well a population grows and how well it keeps up it’s population.

Question 4

Inputs + outputs –> Photosynthesis

Answer 4

Sunlight+ co2+h2o –> o2 + glucose

Question 5

Inputs + Outputs –> Respiration

Answer 5

o2+ glucose –> energy + co2 + h2o

Question 6

What type of organisms perform the processes of photosynthesis and cellular respiration

Answer 6

Plants

Question 7

What is shown in a pyramid of energy vs. a pyramid of numbers vs. a pyramid of biomass

Answer 7

-Energy = Flow of energy
-Biomass = The shift of biomass as the levels go up
-Numbers = The shift of numbers as levels go up (can be inverted)

Question 8

Apply the rule of 10 to an energy pyramid to determine the energy available at each trophic level

Answer 8

Producer= 200
Primary= 20
Secondary= 2
Tetiary= 0.2

Question 9

Explain why it is considered more efficient to eat at a lower trophic level vs. a higher trophic level

Answer 9

It is more efficient because there is more things to eat than higher levels.

Question 10

Predict how the amount of solar energy in a location relates to productivity

Answer 10

The more solar energy means the plants can grow more plentiful, the primary consumers have more plants to eat, the secondary consumers have more prey, and so on.

Question 11

Predict how the amount of solar energy in a location relates to biomass
