• grass

• mouse

• rabbit

• hawk

In the picture shown above, energy flows directly from the kelp and seaweeds to which other organism?

• sea urchins

• larger crabs

• small fishes

• all of the above

Observe the forest food web above. After a forest fire, many of the animals move to a different location because there is no food available in the ecosystem. The first plants to return to the ecosystem are the grasses.

Based on the food web above, the first animals to return to the ecosystem are —

• deer

• grasshoppers

• finches

• chipmunks

In the diagram, which of the following organisms would have the greatest impact on the food web if it were removed?

• oak tree

• hawk

• chipmunk

• rabbit

Which of the following is NOT needed for a producer to make its own food?

• oxygen

• carbon dioxide

• water

• sun

Which food chain correctly identifies the flow of energy?

• 
• 
• 
• 

How tall is the plant if rounded to the nearest cm?

• 13 cm

• 13.4 cm

• 13.9 cm

• 14 cm

Food provides animals with the materials and energy they need for growth, warmth, and motion. Plants get material for growth mostly from air and water, and obtain energy from sunlight. Producers provide food to consumers because ?

• many animals prefer eating plants to eating meat

• plants can easily make food from soil and water

• animals cannot produce their own food

• plants are more abundant in ecosystem

A student conducts an experiment to see how the amount of light a plant receives affects its growth. He gives Plant A two hours of light, Plant B four hours of light, Plant C six hours of light, and Plant D eight hours of light.

Which is the most valid conclusion for an investigation on plants and light?

• Plants receiving two hours of light have the greatest increase in height.

• Plants need no more than four hours of light to grow the most.

• The more light a plant receives, the more the plant’s height increases.

• Plants that receive at least six hours of light grow the best.
