Transcript of Mono Lake Food Web

Day 7 - Mono Lake Food Web Define the term ecosystem. One way organisms in the Mono Lake ecosystem interact with one another is by eating each other.

This is called a feeding relationship. A number of important organisms in the Mono Lake ecosystem are featured on these cards.
Each card has
A photograph of the organism.
Its common and scientific name.
Information about its life cycle and population dynamics.
Information about how it obtains its food.
A description of its role in the ecosystem. Work in a group with a deck of cards.

a. Read the cards to become familiar with the organisms and their natural history.

b. Organize the cards on the table, picture side up.

c. Draw arrows on paper strips. Use them to show feeding relationships between organisms.

d. Every organism should be included in this feeding relationship project. If an organism is involved in two or more feeding relationships, all the relationshps should be indicated with arrows. Do spider and flies have a feeding relationship? Which organism eats the other? In an ecosystem, many organisms survive by eating other organisms. The benefits of the food eaten by one organism can then move to another organism and another, as each one is eaten. The path that food takes from one organism to another organism is called a food chain. Many of the organisms in your feeding-relationship projects are connected with more than one arrow. Some organisms, like phalaropes, eat more than one organism. And some organisms, like brine shrimp, are eaten by many organisms. When you connect all the organisms with arrows, the arrows cross each other in a complex way. A diagram that shows all the feeding relationships is a food web. Which organisms in the food web do not eat any other organism? How can they survive without eating? Organisms that make food are producers. Producers produce the food that is used in an ecosystem. In the Mono Lake ecosystem, algae are the producers. Producers like algae make their own food, but animals, like brine shrimp and gulls, don't make their own food. How do animals get their food? Organisms that eat other organisms are consumers. Consumers get their food from the bodies of other organisms.
