Food webs are made up of many food chains woven together. For this reason, many prairie potholes have been drained and the land used for agriculture. Academy Press, 1995. Some of the organic molecules an organism eats cannot be digested and leave the body as feces, poop, rather than being used. A wetland food chain shows the linear transfer of energy through trophic levels using arrows. Energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from its prey's body. The round-leaved pig face is a succulent plant found along salt marshes and coastal rocks. A food chain in the wetlands is a diagram of different organisms and how they transfer energy to each other. The cow is a primary consumer, and the lettuce leaf on the patty is a primary producer. Secondary production by these primary consumers supports higher trophic levels, including predatory insects, fishes, reptiles, amphibians, birds, and mammals. Edited by G. W. Gurt et al. Newsroom| The ecosystem acts as a filter for toxic chemicals. Seagrasses are a prominent producer found in marine wetlands. Ornate Box Turtles feed on caterpillars, grasshoppers and beetles. Seawater can also create wetlands, especially in coastal areas that experience strong tides.A wetland is entirely covered by water at least part of the year. ACTION: Proposed rule. Hydrologic pulses can alter productivity along a flooding gradient by altering the extent of flood subsidies and stresses in a wetland (Figure 2). As such, hydrology is rarely stable but fluctuates over time resulting in pulsing hydroperiods. The depth and duration of this seasonal flooding varies. The development of these productive and often diverse plant communities fuels complex food webs that not only sustain microbial communities through large inputs of detritus to wetland soils but also support diverse communities of animals that utilize wetlands for part or all of their lives (Figure 5).
