unit exam - populations
what would happen to the largemouth bass population if there was a drastic increase in prey populations?
the largemouth bass population would be completely unaffected.
the largemouth bass population would dwindle away and eventually become extinct.
the largemouth bass population would likely exhibit exponential growth.
the largemouth bass population would completely disappear from the lake.

Explanation:

In an ecosystem, if the prey population of largemouth bass (their food source) increases drastically, there will be more available energy and resources for the bass. With abundant food, the bass will have higher survival rates, more successful reproduction, and less competition for resources. This favorable environment with sufficient resources typically leads to a population growth pattern, and exponential growth is a common pattern when a population has access to unlimited resources (in this case, a drastic increase in prey means a significant boost in available food, approaching a situation of relatively unlimited resources for the bass population in the short - term). The other options are incorrect: the population can't be unaffected as food availability is a key factor, it won't dwindle or disappear as more food is available, and it won't completely disappear from the lake.

Answer:

The largemouth bass population would likely exhibit exponential growth.
