Answer:
All of the above are true.
Explanation:
The prokaryotic organisms are the unicellular primitive organism which was formed in the primitive time when the conditions on the Earth were harsh.
The prokaryotes developed the metabolism to survive in the extreme conditions and were recognised as the archaebacteria. These bacteria can tolerate extreme condition like hot temperature called thermophilic conditions. These thermophiles can grow at higher temperature conditions than the eukaryotes.
The thermophiles are non-phototrophic organism as they do not utilize the light energy to produce energy as phototrophic organisms does.
Thus, all of the true is correct.
Answer:B. The level of carbon in the atmosphere will increase because there are fewer sinks in the ecosystem.

<h2>Endothermic Process</h2>
Explanation:
An example of endothermic process is :
Heat is needed for water to boil.
Endothermic process can be defined as a process in which heat energy is absorbed from the surrounding that bring about changes in the molecular level like breaking chemical bonds, inter-molecular force of attraction etc.
Boiling of water is an endothermic process because during this process water absorbs heat , its kinetic energy increases and then it boils.
Answer:
Although more offsprings are produced by the process of external fertilization but the process of internal fertilization is more efficient as compared to external fertilization. This is because, in external fertilization, it is more difficult for the sperm to find the egg and fertilize it. Even after fertilization, it might be that the zygote gets eaten up by a predator. There are none such risks in internal fertilization. The zygote is protected during the internal fertilization which makes this process more efficient.
