1 Algae / phytoplankton Plant (Producer) Get Energy from: the sun; make their own food through photosynthesis. Place in Food Web: (Producer) form the basis of the aquatic food chain Mutualism: provide food and shelter for different organisms, fish and wildlife and also filter sunlight limiting growth of plants on the bottom of lakes Photo courtesy of

2 Cattails / Plant (Producer) Get Energy from: the sun; make their own food through photosynthesis. Place in Food Web: (Producer) form the basis of the aquatic food chain Mutualism: provide food and shelter for a variety of organisms, fish and wildlife; nursery habitat Photo courtesy of

3 Phytoplankton / Microscopic Plants (Producers) Get Energy from: the sun; make their own food through photosynthesis. Place in Food Web: (Producer) form the basis of the aquatic food chain. Mutualism: Phytoplankton are the foundation of the aquatic food web. Plankton are vital in the food supplies of fish, aquatic birds, reptiles, amphibians and mammals and aquatic insects.

Place in Food Web: (Producer) form the basis of the aquatic food chain Mutualism: provide food and shelter for variety of organisms, fish and wildlife and also filter sunlight limiting growth of plants on the bottom of lakes. Provides excellent habitat for largemouth bass and sunfish; seeds are eaten by waterfowl; small aquatic animals lay their eggs on the leaves and stems.
