The main reason that most farmers use stem cuttings rather than just planting a seed is that a tree's genetic variation will occur. The seeds of many fruit trees tend to vary differently from the parent, because seeds themselves are produced by sexual reproduction (i.e they receive genes from a male and female to form). As they are a cross from two sets of genes, many fruit trees are not “true to seed”. Their seeds will produce a generally different variety of tree from the parent. When using stem cuttings, it's almost like a cloning process.
The biodiversity would change over time through ecological succession. This can be done many ways. One way would be through a damaging event, such as a forest fire or flood. Then, a pioneer species would start growing. A pioneer species would then lead to increased biodiversity in both antibiotic and biotic factors, therefore strengthening the ecosystem even more.

Answer: Photosynthesis is process of green plants and organisms use sun or UV light to <u>synthesize </u>from CO2 (carbon dioxide) and water to make food. Usually producing green pigment called chlorophyll (what makes leaves green) and oxygen as a byproduct which they do not need.
