28.2% (sunlight energy collected by chlorophyll) → 68% is lost in conversion of ATP and NADPH to d-glucose, leaving; 9% (collected as sugar) → 35–40% of sugar is recycled/consumed by the leaf in dark and photo-respiration, leaving; 5.4% net leaf efficiency. Many plants lose much of the remaining energy on growing roots.
Acidic precipitation is the main natural factor to mobilize aluminium from natural sources [180] and the main reason for the environmental effects of aluminium; [207] however, the main factor of presence of aluminium in salt and freshwater are the industrial processes that also release aluminium into air. [180] In water, aluminium acts as a ...

This is ...
The more sunlight they get, the more water they will need. Plants also will need to be fertilized. Some growers use an organic slow-release granular fertilizer , which feeds gradually throughout ...
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
In a solar still, impure water is contained outside the collector, where it is evaporated by sunlight shining through a transparent collector. The pure water vapour condenses on the cool inside surface and drips into a tank. Distillation replicates the way nature makes rain. The sun's energy heats water to the point of evaporation.
