I had to look for the options and here is my answer:

So in a closed system, the momentum before a collision would be EQUALS the momentum after a collision happens. In thermodynamics, when we say closed system, this is the kind of system that is not affected with any force from its surroundings and still stay the same.

Answer:

Equals

Explanation:

A closed system is an isolated system in which there is no exchange of mass with the environment or any other external forces acting on it. 

Due to the absence of external forces and no exchange of masses the energy and momentum of the closed system get conserved.

Therefore the momentum of the individual's objects before the collision would be equal to the momentum after the collision as only the energies get transferred but the total momentum of the system remains conserved.

All autotrophs produce valuable organic molecules. What makes these organic molecules so valuable to living organisms
Sindrei [870]

Answer:

The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.

Without these valuable organic molecules living organisms can not survive , grow and develop.

The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.

Explanation:

Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.

Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.
