Wetlands Activity Sheets Biology Diagrams Food Chains and Food Webs by Karen Marks Oh what a tangled web we weave, when first we start to feed A simple food chain begins with the sun. Plants absorb sunlight and use this energy in the process of photosynthesis to create simple organic compounds otherwise known as carbohydrates (sugar). This form of "food" provides energy to the plant itself and to animals that eat the plant
A wetland food chain is a diagram that shows the flow of energy through different species in a linear direction. Food chains are divided into layers called trophic levels.

Procedure Read the background material aloud in class. It may be helpful to draw an example of a food chain or food web on the board, and to make a diagram with producers on the bottom, with the primary consumers above them, the secondary consumers above the primary consumers, and so on. Make food web cards (from the list below) on large index Food chain: a series of living things that are dependent on the next as a source of food List some wetland plants and animals in the box below: Now list the words from above in the spaces below to make your own food chain: Wetland Food Chains, continued on page 4 Wetland Food Chains, continued from page 3 Vocabulary to know: n
Wetland Food Web Put on your boots or sneakers, grab an adult, and head to the nearest pond, stream, lake, river, swamp, or marsh. Look closely and you'll discover a diverse community of plants and animals connected in what is known as a food web. Food webs are made up of lots of food chains. Here is an example of a simple food chain: Plant Snail Fish Bird Food chains and food webs show how The "Wetlands" unit includes three activities that are designed to promote an understanding of the transfer of nutrients and energy through food chains and food webs. Students recognize the interdependence of all living things by this comparison. The activities illustrate the basic ecological components of a wetland ecosystem, their relationship via food chains, and finally the flow and loss

Explore the intricacies of wetland food webs, uncovering the dynamics that sustain biodiversity and ecosystem health in vital wetlands. Wetlands Exhibit (Teacher's Edition): -Food web/ food chain: Students will come to Sea Center Texas' wetland exhibit and observe the various organisms present. Once the organisms are identified they will be used to create a food web. A discussion will be conducted about the food web and how the organisms are inter-dependent. In the Lake Ontario food chain, shown in figure 6.1.1.4.g 6.1.1.4. g, the Chinook salmon is the apex consumer at the top of this food chain. Some communities have additional trophic levels (quaternary consumers, fifth order consumers, etc.). Finally, detritivores and decomposers break down dead and decaying organisms from any trophic level.
