percentage eficeny transfer = biomass in higher trophic level / biomass in lower trophic level * 100

Question 7

Energy is lost:

Why is biomass not 100% efficent?

Answer 7

• Egestion
• Excretion
• Respiration
  *

Around only 10% is passed on to the next trophic level that is why the top trophic levls have teh lowest biomass

Question 8

How does the efficecy of biomass transfer affect the number of trophic levels in a biomass pryamid?

Answer 8

• less efficent the transfer means less trophic levels and less organsiums in hiigher trophic levels

Question 9

Multiple and singular

What is a diffrence between a food web and a food chain?
