Plants do not grow near the old copper mine because of the excess copper deposited in them impairs cellular processes and inhibits plant growth.
What are micronutrients?
These are required by plants in much smaller quantities less than 1% of the dry weight but are necessary for growth and development. There are 7 essential plant nutrients like boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), and, chlorine (Cl).
Copper activates some enzymes in plants that are involved in lignin synthesis and are required in the process of photosynthesis.
Excess copper causes reduced seed germination, low shoot vigour, and lower iron availability. A deficiency of copper can lead to increased to susceptibility to diseases like ergot, which can cause significant loss in the yield.
Plants growing in the old copper mine have the excess deposition of copper in one place which affects the germination of seeds hence it is found difficult to grow in the old copper mine.
Plants can grow easily in a place that is further away from the old copper mine. Because there is a high concentration of copper dissolved in water in the soil, this helps the plant to grow by exhibiting the photosynthesis process.

Answer:
Should be D. Breathable gases
Explanation:
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, and abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.
