Most of the energyreleased both by the burning of fossil fuels and by the metabolism ofliving cells is given off as heat and must be replaced by thecontinued input of radiant energy from the Sun.The principal organic products of plant photosynthesis arecarbohydrates.
C3 plants have the disadvantage that in hot dry conditions their photosynthetic efficiency suffers because of a process called . When the CO2 concentration in the drops below about 50 ppm, the catalyst that helps to fix carbon begins to fix oxygen instead. This is highly wasteful of the energy that has been collected from the light, and causes the rubisco to operate at perhaps a quarter of its maximal rate.
The raw materials neededfor photosynthesis include ...
Photosynthesis in green plants harnesses the energy of sunlight toconvert carbon dioxide, water, and minerals into organic compoundsand gaseous oxygen.In addition to the green plants, photosynthetic organisms includecertain protists (such as euglenoids and diatoms), cyanophytes(blue-green algae), and various bacteria.

Carbon dioxide and water are inorganic chemicals, whereas glucose is an organic chemical. Plants need energy to convert carbon dioxide and water into glucose; this energy comes from sunlight. Plants can also use artificial light providing that it contains the right frequencies (). Light energy is trapped by a green chemical called chlorophyll. In photosynthesis, light energy is converted into chemical energy. When animals and plants respire, the chemical energy in glucose can be converted into other forms of e.g. kinetic energy.
Plants make their own food thru the process of photosynthesis
The energy provided bycoal, oil, and gas comes from photosynthesis carried on by plants ofearlier times and preserved down through the ages, to be released bycombustion in modern industrial processes.

Moore, et al. point to Flaveria (Asteraceae), Panicum (Poaceae) and Alternanthera (Amarantheceae) as genera that contain species that are intermediates between C3 and C4 photosynthesis. These plants have intermediate leaf anatomies that contain bundle sheath cells that are less distinct and developed than the .
