alexandr1967 [171]

In physical science there are two types of "isolated systems"


1. Being a Physical System in which it is so far removed from other systems that it does not react with any of them.


2. Being a Thermodynamic System in which it is enclosed by rigid immovable walls of which neither mass nor energy can flow through.


I believe in this case although not stated that it would refer to a Thermodynamic System which would leave you with the only plausible answer as ENERGY AND MATTER CANNOT ENTER OR LEAVE.


None of the other answers make sense. Even if it were referring to Physical. Physical does not react with anything at all. An as you can see Thermodynamic does not allow for anything to pass through or leave.

Jason wants to explain the movement of carbon through alr, land, and the ocean. Which of the following is the best model to show
katrin2010 [14]

The best model to show the movement of carbon would be an infographic that shows carbon moving through the ecosystems.

<h3>Carbon cycle</h3>

The carbon cycle is a cycle showing the movement and flux of carbon between the various components of the ecosystem.

Carbon in the form of carbon dioxide is produced into the atmosphere by living organisms when they respire and by anthropological processes such as the burning of fossil fuels.

Carbon in the atmosphere is fixed by green plants in a process known as photosynthesis. When these plants die and decay, the carbon enters the soil.

Carbon is also fixed by aquatic organisms.

Thus, an infographic that shows the movement of carbon through the ecosystem would be the best model to show carbon movement.
