Because of the problems of modelling, today scientific literature contains no known heuristic approaches that would represent alternative to mathematical model switch are used in evaluating investment in technical systems.
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.Photosynthesis in green plants harnesses the energy of sunlight to convert carbon dioxide, water, and minerals into organic compounds and gaseous oxygen.hotosynthesis in green plants harnesses the energy of sunlight to convert carbon dioxide, water, and minerals into organic compounds and gaseous oxygen.
1 photosynthesis A chemical process used by plants and algae to make glucose and oxygen from carbon dioxide and water, using light energy. 2  Oxygen is produced as a by-product of photosynthesis. 3  stomata Tiny holes in the epidermis (skin) of a leaf-usually on the undersides of leaves.hotosynthesis. Plants make food using photosynthesis. This needs light, carbon dioxide and water. It produces glucose, and oxygen as a by-product. Leaves are adapted to carry out photosynthesis.
