Explanation:
Survival of the fittest is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection.In On the Origin of Species, he introduced the phrase in the fifth edition published in 1869, intending it to mean "better designed for an immediate, local environment".
Simple answer is that the plants are conducting more photosynthesis than all the organisms in the tank are carrying out cellular respiration. This would be why the carbon (CO2) levels are decreasing. They are being incorporated into the plant as sugars.
By natural selection, the nature of species gradually changes to become adapted to the environments. This variation of traits in a population is what gives the organisms the ability to survive environmental changes. If not the species becomes extinct.
