​ LO: SWBAT describe the flow of energy through food webs, beginning with the Sun, and predict how changes in the ecosystem affect the food web and explore how structures and functions enable organisms to survive in their environment.


DOL: Given a problem, SW describe the flow of energy through food webs, beginning with the Sun, and predict how changes in the ecosystem affect the food web and explore how structures and functions enable organisms to survive in their environment correctly in at least 3 out of 4 questions.

Multiple Select

Which of these resources are needed by both producers and consumers?

Select TWO correct answers.

• Water

• Seeds

• Soil

• Rocks

• Air

Multiple Choice

Which of these best describes the flow of energy through one food chain of this food web?

• Wild celery → gorillas → okapis → leopards

• Wild celery → grasshoppers → civets → leopards

• Grasshoppers → woody vines → okapis → civets

• Woody vines → okapis → gorillas → civets

Multiple Choice

• 2, 1, 3, 4

• 4, 2, 3, 1

• 3, 4, 1, 2

Multiple Choice

• Producers depend on other organisms for energy.

• Consumers depend on the Sun to make their own food.

• Consumers do not provide energy to producers.

• Consumers provide energy to producers.

Multiple Choice

Which statement BEST supports the answer that consumers do not provide energy to producers?

• Producers do not need energy to survive.

• Producers create their own energy through the process of photosynthesis.

• Producers obtain their energy from other producers.

• Producers create their own energy through the process of evaporation.

Multiple Choice

A diagram of a Texas Piney Woods food web is shown.

Which of the organisms in the food web does NOT obtain energy directly from mice?

• Eastern gray squirrels

• Water oaks

• Great horned owls

• Red-tailed hawks

Multiple Choice

A student observed and compared the life cycles of a frog and a beetle.

Which of the following statements correctly compares the two life cycles?

• Only the frog life cycle has an adult stage.

• Both organisms have an egg stage.

• Both organisms have a larva stage.

• Only the beetle life cycle has an egg stage.

Multiple Choice

A student created a list of organisms that they found in their backyard.

Which table correctly classifies the organisms in the list as producers or consumers?

Multiple Choice

A wetland food web is shown.

Which of the following will happen to this food web if a disease kills all the shrews?

• The grasshoppers will lose their energy source.

• The crickets will lose their energy source.

• The hawks will consume more snakes.

• The frogs will consume more snakes.

Multiple Choice

A student conducts an investigation to observe what plants need in order to survive. He places one plant outside and one plant inside a closet. He gives each plant 200 mL of water every other day for 8 days. The diagram below shows the plants on day 1 and day 8.

What inference can the student make using the information he collected during the investigation?

• The plant inside the closet had no sunlight to use as energy for photosynthesis.

• The plant outside had no shade and was unable to go through the process of photosynthesis.

• Both plants did not receive enough sunlight and were unable to photosynthesize their own food.

• The plant inside the closet did not have enough water and was unable to carry out photosynthesis.

Multiple Choice

A forest food web is shown.

Which of the following shows a food chain that correctly describes the flow of energy between organisms in this food web?

• Grasses and seeds → owls → foxes

• Grasses and seeds → rabbits → mice

• Grasses and seeds → mice → owls

• Grasses and seeds → mice → rabbits

Multiple Choice

Most producers go through a process called photosynthesis to make their own food. Which of the following is NOT a factor that helps plants in photosynthesis?

• Carbon dioxide

• Fresh water

• Sandy soil

• Sunlight

Multiple Choice

A student observes the pond ecosystem food web.

The algae in the food web are plants that grow in water and on rocks. If the student wants to add where the algae obtain energy, what should she add to the food web?

• Water

• Grasses

• Rocks

• The Sun

Multiple Choice

Multiple Select

Observe the images of the living organisms below. Select TWO statements about how they’re alike at the start of their life cycle.

• All organisms do not have inherited traits.

• All organisms start off as an egg.

• All organisms skip the growth and development stage.

• All organisms come from a parent.

Multiple Choice

• Diet

• Instinct

• Environment

• Learned behavior

Multiple Choice
