Answer:
Wetlands such as swamps and bayous have lots of plant and animal life, along with many bacteria, protists, and fungi. All of these, of course, are biotic factors. Some abiotic factors include the soil/mud or sand (not including the living organisms inside of it), rocks, sunlight, water, and gases in the air. There's also a number of chemical components in the water and soil, which can include salts, sulfur, nitrates and nitrites, and ammonia, among others.
