Investigation into the Ecology of a small stream in Tillingbourne Ecology is the scientific study of the interactions between organisms and their environment. Invertebrates are interesting organisms to investigate because they represent an enormous diversity of body shapes, survival strategies, and adaptations. Many invertebrates require clear, cool water, adequate oxygen, stable flows, and a steady source of food in order to complete their life cycles. My aims are to investigate the abundance and distribution of freshwater invertebrates in the stream, and to measure abiotic factors such as oxygen levels, in the stream. Prediction I predict that there will be a higher number of organisms at the edge of the stream, than in the middle. Introduction I make this prediction as there is increased vegetation at the edge of the river meaning that more oxygen is released as the plants photosynthesise, from which organisms can respire. The vegetation also provides food for herbivores...
