The genetic equilibrium represents the condition of a genotype or an allele in the genetic pool of a particular population, where there are no changes in the frequency in the successive generations. This basically means that the population has managed to reach the peak of its evolution for the environment in which it leaves, so there's no evolutionary pressure for changes.
In order for the genetic equilibrium to be maintained for prolonged period of time, the population should not face any evolutionary pressure that will cause changes in it. In essence, this means that the environment in which the population lives should remain exactly the same as it is for longer period of time, so the population will have no need to change its appearance or behavior.
Answer: I do not know if this is correct, but this is what I answered.
Explanation:
They are recycle within the ecosystem being constantly reused ( B ) is the true statement
The energy from the sun is use in the formation of nutrients in plants that is consumed by the primary consumers ( Herbivores ) in the ecosystem, while the primary consumers will be consumed by the secondary consumers ( carnivores ). these waste product from the secondary consumers is decomposed by the tertiary consumers ( Fungi and bacteria ) to be reused by the Plants again.
Hence we can conclude that the true statement about the chemical elements in the eco system is that they recycle within the ecosystem being constantly reused.
