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.
Plants require photosynthesis to make their own food (glucose) from water, carbon dioxide, and sunlight. They use a process called cellular respiration to break the glucose do â¦ wn into energy that the plant can use.Animals require the food and oxygen produced by photosynthesis for cellular respiration themselves.Plants, on the other hand, need animals' carbon dioxide in order to photosynthesize. Therefore, all life on Earth depends on photosynthesis. 1 person found this useful.. Photosynthesis is used to produce food from light, this is the most basic foundation of almost all food and life cycles on earth (primary producers). 2. Photosynthesis help â¦ s moderate the carbon dioxide levels of the planet.
