Answer:
If the carrying capacity of the goldfish pond is reduced from 125 to 90, then the pond can sustain a fish population of 90 or fewer, specifically allowing for populations of 90, 75, and 50 goldfish.
Explanation:
The choices provided in the question include:
- The pond can support 125 goldfish.
- The pond can support 110 goldfish.
- The pond can support 90 goldfish.
- The pond can support 75 goldfish.
- The pond can support 50 goldfish.
In population dynamics, the carrying capacity is defined as the upper limit on the number of individuals able to inhabit a specified area based on available resources like food, space, and water, pertinent to ecosystems as well.
A decline in the carrying capacity to 90 goldfish indicates that the resources can only sustain a population that is equal to or less than 90; thus, it can be stated that:
- The pond can support a fish population of 90.
- The pond can support a fish population of 75.
- The pond can support a fish population of 50.
When a species exceeds its carrying capacity, mortality rates typically rise.
