“Plant growth is dependent on the amount of fertilizer applied.” That was the hypothesis Mel and Bill decided on for their scien

ce project. They planted identical seeds in the same potting mix, in similar pots. Each pot received the same amount of water and all the pots were placed in the same location in the greenhouse. Mel and Bill’s data was summarized after three weeks.
What would be the MOST appropriate conclusion for this experiment?

A. High applications of fertilizer will kill the plants.
B. Fertilizer application had no real effect on plant growth.
C. Optimal plant growth is attained by applying fertilizer.
D. An application of 3 grams of fertilizer produced the largest plant in three weeks.

Answer: B. under use; it is a scarce resource.

Explanation:

Early settlers in the town of Dry Gulch drilled wells to pump as much water as they wanted from the single aquifer beneath the town. (An aquifer is an underground body of water.) As more people settled in Dry Gulch, the aquifer level fell and new wells had to be drilled deeper at higher cost.Residents of Dry Gulch have a private incentive to under use water because it is a scarce resource.

In the area near an old copper mine,no plant grow. Go further away more and more plants are growing. An analysis of the soil nea
maks197457 [2]

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.
