Majority of the energy consumed by an organisms is:
stored in the tissues.
is available to the next trophic level.
is used to maintain life and loss as heat.
is accumulated as fat.
What is the efficiency of energy transfer between trophic levels of an ecological pyramid or a food chain?
90% since majority of the energy is made available to the next trophic level.
10% since majority of the energy consumed is used up by the organism.
90% since very little is lost as heat.
25% since this is the amount that is stored in the cells and tissues of the organism.
