No. Plants use light energy from the sun to make sucrose, glucose through photosynthesis, through which primary consumers and their subsequent consumers can convert to energy. Photosynthesis also provides oxygen for all organisms to survive. Combined, they form a vital part in aerobic respiration, as seen in the formula:
C6H12O6 + 6O2 - - - - - - -> 6CO2 + 6H20 + 38ATP*
Meaning Glucose + oxygen -> carbon dioxide + water + energy*by using energy from photons of light the plant can assemble six carbon sugars, a conversion of light energy to potential energy. Then the plant can break the bonds of the sugars releasing the potential energy to do necessary work it needs for life.*ATP: An energy-rich chemical that contains a chemical energy that, when combined and reacted with water, can be used for other metabolism.Also, marine animals depends indirectly on photosynthesis as photosynthesis maintains the pH (acidity) level of the ocean water. Increased acidity will causes marine animals such as corals , shellfish and pteropods to suffer reduced calcification(a process in which calcium salts build up in soft tissue, causing it to harden).Photosynthesis removes CO2 (Carbon Dioxide) .Excess CO2 causes Hypercapnia,caused when there is too much CO2 in the blood. This can lead to headache, confusion and lethargy or even increase blood pressure! In conclusion, photosynthesis is important to all life forms, not only plants and can have disastrous effects if it is removed or even reduced.
