Answer:
Because the biodiversity decreases.
Explanation:
An ecosystem is richer when it has a higher biodiversity, remember that each living thing has an specific role in the food web. When in an ecosystem this web is bigger, increases the probability of sustain a living thing. For example, in the sea, if there is a fish, this is going to be more probabilities of survive if this fish can eat different plants or other fish. But if in the ecosystem there are not a variety of them, it probability to survive is less if one of it food desapear.

Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
