Answer:Many bacteria and fungi are important in the environment because they return energy to the environment
Explanation:
Organs , fins is the correct answer
Answer : The The correct option is, If there is energy lost in the collision to sound, heat, etc., the collision is inelastic.
Explanation :
- Elastic collision : It is defined as in which there is no loss of kinetic energy in the collision.
- Inelastic collision : It is defined as in which there is a loss of kinetic energy in the collision and this energy changed to another form of energy.
If the collision involves bouncing, it is inelastic because kinetic energy is not conserved.
If the collision involves sticking together, it is inelastic because kinetic energy is not conserved, it is changes to potential energy.
I think its because we don't know how to harness it, with out making things explode.
