The process of meiosis is the cell division that prepares the species for sexual reproduction. Through meiosis cells goes from diploid (2n) cells to haploid (n) gamates. Each daughter cell carries exactly one half of the genetic material from the mother cell. In females the result of meiosis is the production of egg cells, where in the male, the result of meiosis is the production of sperm cells.
Answer
C. The amount of energy available decrease with the addition of each link
Explanation
A food chain model is a presentation of the energy and matter flow through an ecosystem. Most food chains have no more than four or five links because too much links in a single food chain will result to inadequate food to the animals at the end. When the links surpass four or five, less energy will be available for the animals at the end of the chain.
