PLEASE HELP ME ALREADY Which of the following is NOT a valid reason that less energy is transferred at each level of the food chain?
A. Energy is released as heat energy during respiration

B. Energy is destroyed because animals are higher levels do not need as much energy

C. Energy is used for life processes (e. g. Movement, breathing, etc.)

D. Energy is egested in feces or remains in dead organisms which are passed to decomposers

C. Energy is used for life processes (e.g. Movement, breathing, etc.)

Explanation:

As we pass from one trophic level to the next, only 10% of energy is transferred from the first trophic level to the next. This is because a lot of energy is lost to the surroundings and rest is utilised by the organism.

B. Energy is destroyed because animals are higher levels do not need as much energy

This statement says energy is destroyed when we should know that energy cannot be created or destroyed. It can simply be transferred while doing numerous tasks, movement and respiration or the energy is egested and remains in dead organisms which passes to decomposers. Respiration releases energy from food in the form of adenosine triphosphate and heat.

hypothesising or postulating

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
