Solution
The correct option is D Many nutrients come from the soil, but carbon comes from the air
The correct option is D
The explanation for the correct option:
- Local variables, such as high rainfall or plant clearance, may limit the quantity of nitrogen, phosphorus, or calcium accessible to a given ecosystem, but carbon availability is rarely an issue.
- Plants consume carbon in the form of carbon dioxide (CO2), which is abundant in the environment.
Final answer: Amount of carbon available to the system is seldom a problem because many nutrients come from the soil, but carbon comes from the air.
