Response:
d. all of the above
Clarification:
In this context, carrying capacity relates to the maximum size a particular species can reach before survival becomes problematic due to resource scarcity. This means that a species' carrying capacity in any environment relies on having enough food and shelter for the current population and the presence of predators in that setting. The latter significantly influences carrying capacity, as a higher number of predators typically results in fewer individuals of the target species surviving.
The planets located in the Outer part of the solar system include Jupiter, Saturn, Uranus, and Neptune. Despite being composed of lighter elements, these planets possess a solid core. Their atmospheres are primarily made up of hydrogen and helium. Additionally, Neptune and Saturn also include methane among their constituents.
I believe the first option should be 2, and for the second options, number 2 is right.
