Question 1

If the algae biomass is 4.58 g, then by using the 10% rule, calculate the catfish biomass

Answer 1

appx. 0.46 g

Question 2

If the grass biomass is 7.86 g, then by using the 10% rule, calculate the grasshopper biomass

Answer 2

appx. 0.79 g

Question 3

Is it more efficient to eat at a lower trophic level or a higher trophic level?

Answer 3

Lower trophic levels have more energy than higher trophic levels, so by consuming lower trophic levels then our energy will be used more efficiently.

Question 4

how does the amount of solar energy affect productivity?

Answer 4

generally speaking, more solar energy increases the productivity of a producer and therefore its consumers.

Question 5

how does the amount of solar energy affect biomass?

Answer 5

since more solar energy increases productivity and productivity is how much energy is added to an organisms biomass, so there would also be more biomass.

Question 6

True or False;
it is more efficient to eat at a lower trophic level because there is a higher energy level

Answer 6

true

Question 7

True or False;
more solar energy negatively affects productivity

Answer 7

false; solar energy generally increases productivity
