Example Food Chain: What type of
consumers are here?
Who will get the most energy
out of this food chain?
Reality Check
• Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?
Food Web Contains lots of food chains.
Everything is connected and energy is being transferred in many ways!!!!!
Food Web Example

Reality Check
• Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?
Instructions:
After your cut and paste, turn to page 75 complete the following pictures. You can title this page Food Chain and Web Pictures.
1. Draw a Food Chain. You must include a producer,2 consumers, and decomposer. Label each and use color
2. Draw a Food Web. You must include 2 producers, 4 consumers, and 2 decomposers. Label them and use color
Symbiosis
• Objective:
Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?
Mutualism
• Both species benefit.
• Butterfly benefits from getting nectar.
• How does the flower benefit from this relationship?
Commensalism
• One of the examples in the ocean is seen in sedentary crustaceans known as barnacles. These are very sedentary crustaceans, and so, they usually attach themselves to a substrate in the sea like rocks or preferably whales, seat turtles, etc. When whales and such creatures travel, the barnacles get access to nutrient rich waters and often, the morsels of food that are left behind by the whale, the barnacle catches it and eats it. These barnacles do the same thing when they attach themselves to the bodies of green sea turtles.
