How does mutation change allele frequency A. It forces evolution to happen by introducing new adaptions.

B. It causes some individuals to go extinct because their mutations hurt their chance of survival.

C. It adds new genes into the gene pool that didn't exist there before.

Explanation:

Mutations add new alleles into a gene pool. This causes a change in the frequency of certain allele combinations in the population, which will cause the population to evolve over time. They are a major evolutionary force that creates new gene variations.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
