<h3>Energy transfer in the ecosystem</h3>
Energy is transferred from lower to higher trophic levels of the food chain in any ecosystem.
In other words, energy is transferred when primary consumers feed on producers, when secondary consumers feed on primary consumers, and so on.
However, when energy is transferred through feeding from lower to higher trophic levels, a certain percentage of the energy is lost to the surroundings as heat.
In actual fact, scientists believe that about 90% (and not 30%) of the energy is lost as heat to the surrounding. Only about 10% of the energy is converted to useful energy.

Answer:
<em>The correct option is C) The helicase enzyme unwind the DNA molecule into two strands.</em>
Explanation:
DNA replication occurs in a semi-conservative manner. This means that each strand of the DNA can give rise to a new strand. For the process of DNA replication to begin, firstly it is necessary that the DNA unwinds. Topoisomerases are enzymes which are known to remove the super-coiling of the DNA. Helicases can be described as the enzymes which separate the two strands of DNA from the region where replication has to begin. Hence, option C is correct.
It is the tropic of cancer
