Explanation:
Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: 2 H2O → 2 H2 + O. Efficient and economical photochemical water splitting would be a technological breakthrough that could underpin a hydrogen economy.

Answer:
Angiosperm
Explanation:
The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.
It is least gene dense as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.
In this question, the correct order of flow of energy in an aquatic ecosystem is Phytoplankton → zooplankton → fish → mammal.
<h3>What do you mean by an Ecosystem?</h3>
An environment may be defined as the complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determine its form and survival.
The flow of energy in an aquatic ecosystem depends on the phytoplankton which are known as the producers of an aquatic ecosystem.
Therefore, the correct order of flow of energy in an aquatic ecosystem is described above. Hence, the correct option is B.
