    Some abiotic factors that are needed to keep a plant striving and alive is sunlight, water, topography, soil, and climate.  These factors all help the plant get enough physical nutrients. Some biotic factors that plants need to survive are bacteria so it helps the soil be full of nourishing. 
    The team knew that the plants were competing because we needed to put our plants in the back of the flower bed due to the plants needing to grow as tall as possible and if they were in the front they would block all the rest of the plants. All the plants are competing for sunlight, and space.
    The winners and losers are determined by which plants survive. Of course, the 'winners' and 'losers' are not always clear cut due to the average eye is not able to identify which plants are striving over others.
    Mutualism is when two organisms benefit from each other. In this case, the bacteria helps with the roots of the plants getting nitrogen, and the plant helps the bacteria get sugars.
    I think that there is succession shown, but not necessarily natural succession because people have obviously helped create the gardens. It seems more like primary succession because originally there was nothing but cement and now with help from students/teachers there is now a full garden.
