GCSE BIOLOGY ECOLOGY EXAM 2025
NEWEST QUESTIONS AND CORRECT
ANSWERS.
What does abiotic mean - Correct Answers -Non living
what is the purpose of pyramids of biomass - Correct Answers -compare
amount of biomass used in each level of the food chain
show energy flow more clearly
how much light energy that hits plants is trapped - Correct Answers -1%
roughly how much biomass is transferred to the level above it - Correct
Answers -10%
why is that? - Correct Answers -some food passed out in faeces
large amounts of glucose used in respiration
some material lost in excretion
what does the gross loss of energy from one trophic level mean in terms of
organism count? - Correct Answers -as the trophic level increase the no. of
organisms decreases as they need more energy and have less available.
how can food production be increased - Correct Answers -reduce energy
transfer from animals to enviroment
-restict/limit movementn of animals
, -control temp of surrounding(less excretion?)
also they can be fed high protein foods to increase growth
what is a fishing quota - Correct Answers -a limit on how may fish you can
catch
give 2 examples of increasing food yield - Correct Answers -battery farms
for chickens
fish cages for fish suprisingly enough
what does biotechnology allow for, and how - Correct Answers -
microorganisms to be grown in large quantities for food such as the fungus
fusarium which is useful for producing mycoprotein
they are grown in industrial vats called fermenters with carefully controlled
conditions
mycoprotein,tell me about it - Correct Answers -protein rich,low fat,high
fibre, vege
how is mycoprotein produced - Correct Answers -fungus grown on glucose
syrup. in areobic conditions then harvested and purified.
