Answer:
The ultimate level of causation refers to the behavior’s evolutionary significance; how the behavior enhances reproductive fitness. The proximate cause refers to the immediate cause of a behavior, whether that be hormonal, neurological, cognitive, interpersonal, or cultural. For example, the proximate cause of humans eating more cookies, cake, and ice cream involves the psychological tendency to desire and enjoy foods with high sugar and fat content. The ultimate cause involves the high caloric content of both sweet and high fat foods, which promotes physical survival in resource-scarce environments.

Explanation:
Green plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.Plants need minerals for healthy growth. They are absorbed through the roots by active transport as mineral ions dissolved in the soil water.Magnesium ions and nitrate ions are needed by plants. A plant will not grow well if it cannot get enough of these ions, and it will show symptoms of mineral deficiency. Fertilisers are used to replace minerals used by plants.
Nitrogen fertilisers - such as ammonium nitrate and ammonium phosphate - provide plants with water-soluble sources of nitrogen that they can absorb through their roots. They allow farmers to increase the yield and quality of their crops. However, overuse can cause problems. Eutrophication happens when excess nitrate (or phosphate) enters rivers or lakes from fields. This can lead to the death of fish and other aquatic animals.
