Answer:
D. Plastic sheeting, ultraviolet lights, dams, mechanical equipment and pesticides
Explanation:
The agriculture has changed significantly in the past couple of centuries. With the start of the industrial revolution, the agriculture was gaining more and more products and technologies to make it make easier for working, safer from pests, providing artificial conditions for the plants, and having higher quality and quantity. The mechanical equipment made the work much easier, cheaper, quicker, and more efficient, replacing lot of labor force. The pesticides have contributed to minimizing the effects of the pests. The dams are providing water for the plants where there's not enough in certain periods of the year. The plastic sheeting manages to stop weeds from growing, keeping higher temperature and moist for the plants, making them grow better and quicker. Some plants do not receive enough sunlight, or have to grown in regulated conditions, so the ultraviolet lights provide the needed light for them to prosper and perform photosynthesis.

Answer: Option (D)
Explanation: In the water cycle, water is transported from the oceans, seas and lakes to the atmosphere, which then again falls back due to precipitation.
Plants also absorbs water by their roots and releases back into the atmosphere by evapo-transpiration process. Some of the water gets percolated into the ground and gets mixes up with the groundwater.
Thus all the provided options fulfills the condition for water cycle except the last one, i.e dissolution of CO₂ in the ground water or the land surface is not considered to be a part of water cycle.
Hence the correct answer is option (D).
