Topic 7 Biomass Transfer

Question 1

Producers such as green plants and algae is energy transferred by like to make food during photosynthesis of the energy that hits the producers how much is transferred for photosynthesis

Answer 1

One percent

Question 2

What is glucose used by the plants and algae to make

Answer 2

Biological molecules which make up the plant biomass

Question 3

What is biomass

Answer 3

The mass of living material and stores energy

Question 4

How is biomass transferred through the food chain

Answer 4

When organisms eat other organisms however not much biomass gets transferred from one trophic level to the next

Question 5

How much biomass is passed on to the next level

Answer 5

10%

Question 6

Why is biomass lost between levels

Answer 6

Organisms don’t eat every single part of the organism they are consuming e.g. bone
Organisms don’t absorb all the stuff in the food they ingest the stuff they don’t absorb is digested as faeces
Some of us is converted into other substances that are lost as waste
Glucose is used in respiration and produces lots of ways carbon dioxide and water urea is another waste product

Question 7

How to calculate the efficiency of biomass transfer

Answer 7

Efficiently = biomass transferred to the next level / biomass available at the previous level x 100
