For living organisms, which of the following is an important consequence of the first law of thermodynamics?
a) the energy content of an organism is constant.
b) the organism ultimately must obtain all of the necessary energy for life from its environment.
c) the entropy of an organism decreases with time as the organism grows in complexity.
d) organisms grow by converting energy into organic matter.
e) life does not obey the first law of thermodynamics.

B). The organism ultimately must obtain all of the necessary energy for life from its environment.

Explanation:

Energy can never be created and it can not be destroyed. Energy can only be transferred from one form into another form. This is according to the First law of thermodynamics. Therefore all living organisms in the universe has to derived or obtained energy from other sources from its environment to sustain life. It can never create any kind of energy on its own. For example plants take the energy from sun to produce food for photosynthesis and animals take energy from different producers in order to sustain life.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
