Top 10 causes of death worldwide. Of the 56.4 million deaths worldwide in 2015, more than half (54%) were due to the top 10 causes. Ischaemic heart disease and stroke are the worldâs biggest killers, accounting for a combined 15 million deaths in 2015. These diseases have remained the leading causes of death globally in the last 15 years.
photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
They are actually the complete opposite! Photosynthesis is when energy, carbon dioxide and water react to produce glucose and oxygen. It is an endothermic reaction (takes in more energy than it gives off). Respiration is the process of producing energy from glucose. It uses glucose and oxygen to give water, carbon dioxide and energy (this making it exothermic). In plants, they make their own glucose using the suns energy, then respire to allow them to use the glucose for energy they can use.
