Poaching is the act of illegally killing an animal. The very prominent subject of poaching is the rhino, some species of which are now virtually extinct due to extensive illegal hunting. However, many other animals are also poached. For example, elephants are poached for the ivory in their tusks. Tigers are poached as trophy animals or for traditional medicine. Sea turtles and lemurs also suffer a similar fate for similar reasons.
The poaching of these animals has driven their population into corners, where they face imminent extinction. Although rehabilitation efforts are extensive, it is unlikely that the populations of these animals will recover unless the poachers are stopped first.

Answer/Explanation:
Green plants can synthesise their own food by using light energy from the sun to convert carbon dioxide and water into glucose, with the release of oxygen. This process is called photosynthesis, and it occurs in specialized organelles called chloroplasts. The first stages of photosynthesis require light energy, and are often called the light-dependent reactions. The next stages occur in the absence of light energy, called the light-independent reactions.
In the light-dependent reactions, chlorophyll in the chloroplasts absorb light, converting into stored chemical energy in the form of NADPH and ATP. The high energy electron produced by light absorption travels down an electron transport chain, driving the pumping of hydrogen ions and creating a gradient. This provides the energy to produce ATP by ATP synthase
This process is used to provide for the light-independent reactions to form carbohydrates from carbon dioxide during a process called the Calvin cycle. The carbohydrates produced during photosynthesis are broken down during cellular respiration to generate ATP.
