Great change occur in big fish population with the introduction of thousands of small fish.

If someone adds thousands of small fish to a lake the number of big fish increases if their food is these small fishes because more food is available for it which results in the increase of population of big fish.

While on the other hand, if the small fishes feed on the same food on which the big fish feed than there is competition which negatively affected the big fish and decrease in population due to unavailability of food so we can conclude that big change occur in big fish population with the introduction of thousands of small fish.

Answer from: jose9794

The number of large fish will increase.

Explanation:

If in a particular lake, thousands of small fishes are added, then the number of the larger fishes will increase. The reason for this is because in general the larger fishes are feeding on the smaller fishes, thus with the introduction of the thousands of small fishes there will be an increase in their food source. Also, the smaller fishes have much quicker reproduction, so the chances are that they will reproduce quickly enough so that they increase in numbers, thus providing constant food source that will enable the support of larger populations of the larger fishes.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
