pond ecology is best described as the interaction of the life in your pond with the environment that exists there. A shallow, nutrient rich pond, exposed to sunlight with little water flowing through it will be teeming with algae and aquatic plants. It may have very little animal life present because of low oxygen levels. In contrast a newly created, deep, spring fed pond may have little life of any kind in it because of low temperatures and lack of food supply.
All ponds age. A pond begins with mostly water, few nutrients, and little aquatic life. Over time the pond accumulates nutrients. This enrichment process is called eutrophication.
hope this helps :) and if you guys need any more help about this stuff just feel free to ask cuz my granpa knows all about this stuff and i always ask these types of questions
