Answer:
False.
Explanation:
Mars is the planet we are most likely to colonise due to the signs that there may have been some sort of life there before.
Answer:
In an ecosystem, all organisms benefit in the process of transformation of energy.
Explanation:
An ecosystem works thanks to the constant transformation of energy. In the case of microorganisms that act as producers, they benefit the rest of the ecosystem in terms of energy transfer because they acquire the energy from a lowest trophic level to make it available for higher trophic levels.
In the case of the primary consumers, they are feeding from the primary producers, incorporating that energy to be part of the food chain. For example, bacteria in the soil are primary producer microorganisms; they transform organic material to make it available for small individuals. A soil worm is a primary consumer microorganism which will feed from this organic material transformed by the bacteria. The worm will then produce food and will be food for herbivores to continue with the flow of energy in the food chain.

Answer:
D. The total energy of a system can increase only if energy enters the system
Explanation:
According to the law of Conservation of Energy, energy can neither be created nor destroyed but can be transformed or converted from one form to the other.
A system has the same energy until there is an addition of energy externally. When energy is added, it will lead to an increment in energy. So, when work is done to the system or the system heated, energy increases.
