Explanation / Answer
The main theme that is learned from the episode is that almost all the vast ocean is there alive in a single drop of ocean water. We can imagine how big the living world is. We, humans, are nothing but a small drop of it, as well as of the whole universe. By having empathetic understanding of the value of this world we live in and of the obligation we have not to destroy it, poison it, deprive it of the many manifestations of vitality it all its forms for the sake of mankind as well as the living world and also for the universe as we see it.
1. The Fish Egg: They are potential contribution to the food chain either as immediate feed for other fish or as future feed for larger predators including possibly ourselves. They belong almost at the base of the food chain and upon them the whole living ocean is dependant to gain their energy.
2. Copepods: These are tiny shrimp-like crustaceans, common zooplankton that are the most basic source of protein for countless fish species, thus helping millions of oceanic species to live upon them and indirectly the terrestrial species who are indirectly benifitiated by the specieses who ate copepods. These animals are energetic swimmers with a well-developed nervous system that provides active motility to evade capture, therefore are of great importance for the evolutionary history writers.
3.Cyanobacteria: These have coiled filaments and among the most primitive life forms that use sunlight to produce food (photosynthesis) and liberate oxygen into the atmosphere for us to breathe. They are among those organisms who first developed the process of photosynthesis depending upon which basic food chain of the living world is running.
