Practise MYP Biology questions on 6.2 Energy Transfer and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
The living material in an ecosystem that contains stored chemical energy is called __________.
What is the "starting point" for all energy transfer in an ecosystem?
Which biological limitation explains why consumers are strictly dependent on producers for survival?
What happens to the chemical energy in biomass when it is consumed by another organism?
Which of the following metabolic activities is a primary reason that chemical energy within a producer is not fully transferred to the next trophic level?
biomass
trophic levels
inorganic matter
chlorophyll
The chemical energy stored in glucose by plants
The inorganic minerals found in the soil
The kinetic energy of animal movement
The heat released by consumers
Consumers cannot capture and fix energy from non-biological external sources
Consumers convert all ingested energy into heat immediately
Consumers are unable to perform cellular respiration
Consumers do not require chemical energy to maintain body conditions
It is entirely converted to heat
It is entirely stored as new biomass
It is partially used for life processes and partially stored
It is converted back into light energy
Conversion of light into chemical energy
Storage of energy in the form of starch
Absorption of water through the roots
Repair of damaged cellular tissues
