Everything.
No examples or anything.
So everything is missing from "this food chain".
Yes, that's correct. In a food chain, energy is transferred between organisms as they consume each other. Typically, it takes many kilograms of lower trophic level organisms, like plankton, to produce one kilogram of weight gain in higher trophic level organisms, such as humans. This is due to the loss of energy at each trophic level as it is transferred up the food chain.
The word "plankton" is a noun. An example of a sentence using the word would be: Plankton are a vital organism, as they provide food for many of the ocean's creatures.
Dolphins are at a higher trophic level than plankton. Dolphins are consumers that feed on other organisms, while plankton are primary producers that form the base of the marine food chain.
The electron acceptor for humans in the electron transport chain is oxygen.
In unsaturated fats, the fatty acid chain is missing some hydrogen atoms, causing double bonds to form between carbon atoms. This results in less saturated fatty acids, which have a lower melting point and are typically liquid at room temperature.

Plankton itself is not harmful to humans. In fact, many plankton species serve as the base of the aquatic food chain and play a critical role in marine ecosystems. However, some plankton blooms can release toxins that can harm humans if consumed through contaminated seafood or water.
yes, plankton is at the bottom of the food chain.
Plankton
There is no such thing as a missing link. If it were indeed missing how would you know? One may speculate as to the nature of a discontinuity in a chain of evidence, but note the use of the word 'speculate'.
Well, that's a tough one,but I'll answer best i can. If there is one level missing then humans and animals we could ALL DIE.
The bottom of the chain
Plankton
Catfish are all bottom feeders. Their food chain is phyto plankton (tiny plants), zoo plankton (tiny animals), then small fish.
invertebrates such as plankton and some jellyfish
Plankton are at the very very bottom of the food Chain. So, if they go extinct then whatever is the next up the food chain will become extinct and so on. If Plankton go extinct, life as we know it is over.
The organism at the start of the food chain is the smallest organism that the next smallest eats. So if you have to do a faood chain on fish, you would start with plankton, then shrimp, then mackeral, then sardines or such. At the top may be a shark, humans, or other meat eating animals normally.
