This concept is best explained by the second law of thermodynamics. This law deals with the entropy of a system, which is related to the amount of disorder in that system.

If an organism is alone in a ecosystem it will definitely die. A single organism cannot form an ecosystem as it has to interact with other organisms.
There are still many mysteries that science has not explained, but given the continued advance of science and its remarkable success to date, I see no reason to think that there is any mystery which cannot eventually be explained, if sufficient research is done.
Scientific theories do not " prove " things, they explain things. So, before the big bang is not yet explained, as an example.
solar energy that is captured by the autotrophs cannot revert back to the sun.also,the energy obtained by herbivores from plants cannot go back to plants.that is why it is said that energy flow in an ecosystem is unidirectional. sun>plants>herbivores>carnivores.
Development is learning and going through difficult trials where you learn through trial and error. The above statement is invalid because development can be explained in simple terms.
something that cannot be explained
Enigma
Mysteries.
Photo electric emission cannot be explained using wave theroy of light. We need quantum theory.
A sweet pain that only Mother can go through in this Universe, that cannot be explained, that disappears as soon as she looks at her newborn baby.
Chemical bonding cannot be solely explained with the concept of electronegativity. According to generality, it is said that a particular compound has a principal ionic character if it exceeds the electronegativity difference of 1.7 in Pauling's scale.

An aquatic ecosystem is an ecosystem located in bodies of water. Types of aquatic ecosystems are The Marine Ecosystem and The Freshwater Ecosystem.
The concept of this question is backwards. The question implies that somehow the arctic ecosystem has designed itself to meet the needs of the plants and animals that live there. The arctic (or any other ecosystem) does not and cannot do this. The question is (or should be) "How have the plants and animals that live in the arctic adapted to survive in under those conditions?"
