Consumers and Producers in the Littoral Zone include: 

Producers
The producers in the littoral zone mainly consist of plants that are rooted to the bottom of the lake and also algae. They are located in such a shallow area due to their need of excess sunlight in order for photosynthesis to occur. As you see below, the Typha cattail, Myriophyllym water milfoil, and the Sagittaria arrowhead are all found in the littoral zone. 

Consumers
The consumers in this zone are primarily animals such as fish, turtles, crabs, worms, and insect larvae. Turtles and crabs prey on small fish while small fish prey on insects and algae, while insects prey on algae.
