The blood supplies nutrients to the skin cells through a network of capillaries.
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.

A key element that characterizes desert environments is their high rate of water loss due to evaporation, which often surpasses the total yearly precipitation, influencing the types of organisms capable of surviving there.
The boundaries where two tectonic plates slide past one another are referred to as transform plates.
The increase in the size of an axial substituent does not always correlate with an increase in strain energy for the axial form. In some situations, a larger substituent can result in a longer bond between the carbon and the substituent, which does not escalate the relative strain energy for the axial configuration. An instance of this is seen in iodocyclohexane.
