This is a shot of a group of 4 guys, interacting in front of McDonald's in school. They're probably discussing what to get for lunch and are enjoying their chatter whilst in the queue. I position the boy in the white shirt on the axis using the Rule of Thirds, as he is wearing the colour that would provide the most contrast between himself and the rest of his friends. In addition, his other friends are wearing dark-coloured tees.

My trophic interaction is a moss covered tree decomposing in the creek after it has fallen. I believe that the most influential species in my location is green algae, which gathers on the surface of the water. The presence of green algae in my location greatly affects the organisms that I should expect to find in various parts of the creek/ponds. I often find more ducks and turtles in the areas with high algae concentrations and mammals in areas lacking algae. I also noticed the more algae the more frogs that litter my location. If I removed the green algae I would be removing a major food source for many marine organisms. If I removed green algae I would ultimately be removing every species that depends on the green algae in the food web, which I assume is a lot in a wetland. I would expect to see a bottom-down effect where the top predators will crash due to lack of prey. If I replaced green algae with an invasive species I would expect the invasive species to completely take over the body of water. I would expect to see plant matter on the surface of every drop of water, making it hard for light to penetrate for photosynthesis. This would ultimately change the nutrient content of the water in my location to either contain too few or too many nutrients. This affects a marine organism’s ability to live in the water and would ultimately hurt my location.

Frogs, ducks, and turtles are all mainly limited by predation, interspecific competition, and habitat-exclusion.

An impressive installation completely controlled via natural interaction. Unfortunately the whole system was mouse based (eg. moving your hand you just move the mouse pointer. A real shame).
