Most animals use more than one species as food. Therefore, the term food web is a better description of food relationship than the term food chain. A food web is a complex feeding systems that contains several food chains. For example, mice, rabbits and deer eat plants. Owls eat meat and rabbits. Mountain lion eats rabbits and deer. These five species are parts of food chains that together form a food web. The first link in a food chain is always a green plant. Only organisms with chlorophyll, such as green plants, can make food. For example, the first link in the aquatic chains is algae. Most algae are microscopic green plants that produce food by photosynthesis. In photosynthesis, energy from sunlight converts carbon dioxide and water to sugar. Tiny fish in lakes, streams and oceans eat algae. In turn, these tiny fishes are eaten by larger fish. These larger fish are eaten by still larger fish. The food supply for fish is made by algae.This food is then passed through the food chains as one animal eats another. Organisms may be divided into three groups based on how they obtain food. These groups are producer, decomposer and consumer. Organisms containing chlorophyll are producers. Thus, green plants are producers. Animals that eat other animals and plants are consumers. Microbes, one-celled organisms that cause the decay of the dead animals and plants are decomposers. Since, decomposers cannot make their own food, they are also consumers. 1. The main purpose of this passage is to................... A. determine which food chain is the most efficient B. describe the food network among plants and animals C. explain the process of photosynthesis in green plants D. appeal to conservationists to protect endangered 2. According to the author, what is the food web? A. A complicated system of several food chains. B. A society that distributes food. C. The relationship of one green plant to another. D. The spiders use to catch food. 3. Which of the following would most likely be the first link in a food chain? A. Termites. B. Fish. C. Lions. D. Grass. 4. As used in last sentence of the second paragraph, the word passed' could best be replaced by which of the following? A. Moved. B. Approved. C. Attempted. D. Relinquished. 5. The author divides the organisms according to................ . A. how they use energy B. how they obtain food C. how much energy they require in order to move D. whether they live on the land or in the sea 6. Which of the following organisms could NOT be a consumer as described in the passage? A. A microbe. B. A rabbit. C. A tree. D. A fish. 12.
