Answer:
When the carrying capacity in a goldfish pond decreases from 125 to 90, the populations that the pond can support are 90 fish or less, that is, the pond can support a population of 90, 75 and 50 goldfish.
Explanation:
Options for this question:
- The pond can support a population size of 125 goldfish.
- The pond can support a population size of 110 goldfish.
- The pond can support a population size of 90 goldfish.
- The pond can support a population size of 75 goldfish.
- The pond can support a population size of 50 goldfish.
In population dynamics, carrying capacity is defined as the maximum number of individuals that can live in a given place, depending on the resources available, such as space, food and water. This concept is also applicable to ecosystems.
If in the pond the carrying capacity decreased to 90 goldfish means that the available resources are only sufficient to maintain a number equal or less than 90 goldfish, so it can be said that:
- <em>The pond can support a population size of 90 goldfish.</em>
- <em>The pond can support a population size of 75 goldfish.</em>
- <em>The pond can support a population size of 50 goldfish.</em>
When a population exceeds its carrying capacity, the mortality rate in that population usually increases.
