We’ve learned that all organisms need energy to survive. The primary source of energy for all organisms begins with the sun. Sunlight provides the necessary energy for producers (plants) to complete photosynthesis. These producers are eaten by primary consumers (herbivores).These herbivore consumers are eaten by carnivores or secondary consumers. Sometimes, carnivores will eat other carnivores. These consumers are known as tertiary consumers. These interactions can be represented by a simple food chain. A bunch of food chains in the same ecosystem put together can make a food web. Food chains and food webs show the flow energy from one organism to another.
Recall that the arrows in a food chain and a food web show the direction that the energy is flowing. For example, in the food chain above, the energy flows from the sun, to the grass, to the grasshopper, to the shrew, to the owl. The arrows indicate the direction energy is being transferred with arrow pointing away from the eaten (prey or plant) and towards the eater (predator or grazer).
YOUR TASK
Through this Web Quest, you’ll practice making food chains and food webs in a variety of ways.
