Trophic Interaction
This interaction is of two bluegill and their nesting sights.
I would say that the most influential species to my ecosystem would be the sunfish. These fish are highly populated in the marsh area and help to keep the seaweed vegetation under control. These fish will swim through and break up the weeds that overpopulate the area as well as stir up the sand and much on the bottom of the marsh, which helps to disrupt the vegetation. Keeping the weed levels to a minimum is important because they become invasive to other species and make it hard for them to grow and prosper. These fish also help in eating some of the water insects and other small fish and worms keeping their populations in check. If we removed this species I think the most harm would be in the overgrowth of seaweed populations. If the seaweed became too bad pesticides would be brought in and could harm other species in the process. If we replaced the sunfish with an invasive species I think there would be a shortage of food for other fish and a possible overpopulation of other species.
Swans-This species is limited by the amount of predators it has. The Mute Swans are an invasive species in Michigan and cannot be hunted.
Water Lilies- This plant is limited by the amount of space it has within the marsh area due to various other plant species that grow in the same area.
Snapper Turtle- This species is limited by the amount of breeding space it has. With the increase of residential homes in the area the turtles are losing their breeding grounds and have a harder time keeping their young from danger.
