In this food pyramid, about of the available energy is transferred to each level. a) 10% b) 25% c) 30% d) 50%

Option A , 10 %

Explanation:

Only 10% of the energy is passed on to each trophic level of an energy pyramid. This is because most of the energy available at any trophic level is used by an organism in internal bodily activities like  cell respiration, ATP production, several life processes, metabolism etc. Thus, even though a large amount of energy is taken at a trophic level, nearly 90% of it is used by the organism itself and thus only 10% of the total energy is available for passing onto the next level. This is the reason why organism at the apex of an energy pyramid receives  the least energy.

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
