Plants are the backbone of all life on Earth and an essential resource for human well-being (BGCI, 2015). For all forms of life, plants form the basic food staples. They are the major source of oxygen and food on earth since no animal is able to supply the components necessary without plants (Jennifer C, 2014). Plants make food – they are the only organisms that can convert light energy from the sun into food. Plants make oxygen – one of the materials that plants produce as they make food is oxygen gas for animals and people to stay alive. Plants provide habitats for animals – it is a primary habitat for thousands of other organisms. Plants help make and preserve soil – the roots of plants help hold soil together which help reduce erosion and helps conserve the soil.
