Why are there less organisms as you move up the energy pyramid?

that an organism of a higher  level ingests food  that increases as you move up the food chain so there must be more food available from the lower levels so that the required energy is available.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
