Answer:
Cambrian explosion
Explanation:
Cambrian explosion is a geological event that happened during the Cambrian age (541 million years ago). In this period, most of the animal phyla (including marine) appeared and their geological record is preserved in the form of fossils. The period lasted for 13-25 million years. Before this period, the organisms were very simple. They were mostly unicellular in nature and were living in the form of colonies.
The remaining three options are incorrect. They are tectonic events that reflect movement of continents in different geological times. None of them resulted in the diversification of (marine) animal phyla.
It shows that flow of energy in the ecosystem is "Uni-directional" means energy flows only in one direction never reverse

ALL organic molecules contain carbon (C), virtually all of them contain hydrogen (H)
<span>Phospholipids are the type of lipid that make-up the bilayer
of cell membranes. They have an amphiphilic characteristic which enables them
to form lipid bilayers of cell membranes. Phospholipid molecules are composed
of two hydrophobic fatty acid that serve as “tails” and glycerol molecules that
serve as hydrophilic “heads” of cell membranes. Lecithin was the first
phospholipid identified in 1847. It was found in the egg yolk of chickens by
Theodor Nicolas Gobley, a French chemist and pharmacist. Sterols are a common
type of lipid that is found in eukaryotic cells that provide the membrane
fluidity and mechanical strength. </span>
