Which of the following statements is accurate?
PIT_PIT [208]

C. Useful energy out of a system is always less than the energy input of that system.

Explanation:

The correct statement of the given options is that useful energy out of a system is always less than the energy input of that system.

This is in compliance with the third law of thermodynamics which states that "energy transformation in a system is not 100% efficient".

  • At every stage energy is usually lost when it is transformed from one form to another.
  • There is no machine that is 100% efficient.
  • A machine that is 100% efficient will convert all the useful energy in it to do work and even more.
  • In system energy is usually lost as a result of heat and to overcome friction.
  • This reduces the amount of energy out of a system.

Anna11 [10]

Answer:

invasive species are a problem both in anthropogenically altered and natural environments

Explanation:

An invasive species can be defined as a non-native species introduced into a new environment which then becomes abundant. Only in the US, it is believed that there are approximately 4,000 invasive species (some examples include the feral pigs, grey squirrels, European rabbits, etc.). In general, invasive species have a negative impact on the ecosystem, especially by displacing native species and thereby altering the trophic chain. In anthropogenically altered environments (anthromes), human beings are considered to be an invasive species.
