iReady 6 Lesson 2

Which of the following best states the central idea of the article?

• Both long and short food chains make up food webs.

• Food webs connect different food chains and trophic levels.

• Food webs consist of many different food chains, the shortest of which involves grass, rabbits, foxes and decomposers.

• The food chains that make up food webs stay in balance naturally as long as humans don't interfere

Which statement best summarize the central idea and important details of paragraph 3?

• A forest food chain that includes leaves, caterpillars, sparrows, snakes, eagles, hawks, vultures and bacteria is one of the longest in that ecosystem

• One forest food chain begins with caterpillars eating leaves. Then birds, snakes, and larger birds eat each other. Finally, bacteria in the soil decompose the remains.

• A forest food chain starts with trees, leaves and caterpillars. Birds eat the caterpillars and are eaten by snakes. The chain continues until a vulture eats a disgusting dead thing.

• One ecosystem may have many different food chains. One example of a food chain in a forest involves leaves, caterpillars, sparrows, snakes, eagles, hawks, vultures, and bacteria

Fungi play an important role in a food chain. Which evidence from the text best supports this claim?

• When a fox dies, decomposers such as worms and mushroom break down its body, returning it to the soil where it provides nutrients for plant like grass

• A caterpillar may eat the leaves of a tree in the forest

• bacteria in the soil decompose the remains

• The carbon in the bones enrich the desert soil, helping plants like cactuses develop

How is the food web different from a food chain?

• There is no difference

• Specific food chains make up the larger food webs of an ecosystem

• food webs are larger

• food chains only consist of animals

Which of the following is a summary of the text?

• Within an ecosystem's food web, there are a number of different food chains. These chains can involve different organisms form different trophic levels. Examples include food chains for a grass ecosystem, a forest ecosystem and a dessert ecosystem.

• One ecosystem may have many food chains. One example of a food chain in a forest involves leaves, caterpillars, sparrows, snakes, eagles, hawk vultures and bacteria.

• The grass makes its own food through photosynthesis. Then it is eaten by a rabbit, which is eaten by a fox. The fox decomposes and provides nutrients for the growing grass.

• Food webs are the most important part of the ecosystem. Annoying animals die and provide rich nutrients.
