if there is a source of water and single celled organisms, life will be possible on that planet. The planet will need a atmosphere so 1. it will have its own gravity 2. and so that gas molecules ( including oxygen) will not be able to escape into space. the world population will be roughly 10.7 billion people so the planet will need to be spacious. A planet as described would be perfect if you take the right measures. if it has single celled organisms than its proven that it can and will sustain life. So, the planet has a water source, contains living organisms, is spacious, and has a atmosphere.
C is your answer :)
Hope it helps!

Answer:
600 kcal
Explanation:
In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.
Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.
