# 5th Grade Science : Model the energy in animals' food

## Example Questions

### Example Question #1 : Model The Energy In Animals' Food

Which of the following organisms from the food web receives energy from the sun?

Possible Answers:

polar bears

lobsters

fish

phytoplankton

Correct answer:

phytoplankton

Explanation:

Through the photosynthesis process, producers, such as grass, absorb the sun's light energy to produce food (stored sugar and starches). Consumers cannot make their own food, so they have to consume other organisms. The food of almost any kind of animal can be traced back to plants and the sun. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Some organisms, such as fungi and bacteria, break down dead organisms (both plants or plant parts and animals) and therefore operate as “decomposers.” Decomposition eventually restores (recycles) some materials back to the soil. Organisms can survive only in environments in which their particular needs are met.

### Example Question #2 : Model The Energy In Animals' Food

Which of the organisms from the image receives the LEAST energy from their food?

Possible Answers:

the sun

consumer 1

producer

consumer 2

Correct answer:

consumer 2

Explanation:

The answer is "consumer 2" because energy is lost as heat as it moves up the food chain.

Through the photosynthesis process, producers, such as grass, absorb the sun's light energy to produce food (stored sugar and starches). Consumers cannot make their own food, so they have to consume other organisms. The food of almost any kind of animal can be traced back to plants and the sun.

### Example Question #3 : Model The Energy In Animals' Food

Which of the organisms from the image receives the MOST energy from their food?

Possible Answers:

consumer 1

the sun

producer

consumer 2

Correct answer:

producer

Explanation:

The answer is "producer" because energy is lost as heat as it moves up the food chain.

### Example Question #4 : Model The Energy In Animals' Food

What do the arrows most likely represent in this image?

Possible Answers:

the arrows points to an organisms prey

the arrows point in the direction of energy flow

the arrows point to an organisms food source

the arrows point to what an organism eats

Correct answer:

the arrows point in the direction of energy flow

Explanation:

The answer is "the arrows point in the direction of energy flow."

### Example Question #5 : Model The Energy In Animals' Food

What belongs in the blank on the food chain above?

Possible Answers:

autotroph

none of these

all of these

consumer

heterotroph

Correct answer:

autotroph

Explanation:

The answer is "autotroph" because producers are also called autotrophs.

### Example Question #6 : Model The Energy In Animals' Food

A meadow is an ecosystem where snakes and rabbits live. In which order does energy flow through this meadow ecosystem?

Possible Answers:

Grass → Rabbit → Snake → Sun

Sun → Grass → Rabbit → Snake

Sun → Grass → Snake → Rabbit

Grass → Snake → Rabbit → Sun

Correct answer:

Sun → Grass → Rabbit → Snake

Explanation:

The energy in the meadow starts with the Sun. The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.

### Example Question #7 : Model The Energy In Animals' Food

Which of the following statements are correct?

Possible Answers:

Some food chains only have predators.

Energy flows from producers to consumers.

Animals make their energy.

Animals' energy is passed to plants.

Correct answer:

Energy flows from producers to consumers.

Explanation:

Energy flows from the producers to consumers. An example of a food chain where this is happening:

grass → grasshopper → frog → rabbit → hawk

The grass is the producer because it produces its food and nutrients through photosynthesis. The grasshopper, frog, rabbit, and hawk are consumers because they get their energy by consuming other animals or plants. They cannot make their food as plants can.

### Example Question #8 : Model The Energy In Animals' Food

A forested area is home to wild blackberries and raspberry bushes, moose, and raccoons. The wild blackberries and raspberry bushes get energy from the Sun. How do the raccoons and moose get energy?

Possible Answers:

Raccoons and moose get their energy fro hunting large prey in packs and consuming the meat.

The raccoons and moose get their energy from sleeping at night and relaxing during the day.

The raccoons and moose get their energy from eating the blackberries and raspberries.

Raccoons and moose get their energy through the process of photosynthesis.

Correct answer:

The raccoons and moose get their energy from eating the blackberries and raspberries.

Explanation:

The raccoons and moose get their energy from eating the blackberries and raspberries. Raccoons and moose are consumers meaning their energy comes from consuming or eating plants, animals, or a combination of the two. Plants like raspberry and blackberry bushes are producers because they make their food through photosynthesis.

### Example Question #9 : Model The Energy In Animals' Food

Based on the information in the graphic above, which organism receives energy from the seal?

Possible Answers:

Zooplankton

Polar bear

Sea ice

The Sun

Correct answer:

Polar bear

Explanation:

In this graphic, the arrows can be followed through the food chain to determine where the energy is being transferred. The seal's energy is transferred to the polar bear when it is eaten. The sea ice is not a living organism, zooplankton receives its energy from the phytoplankton, and the Sun is a provider of energy and does not consume energy in the food chain.

### Example Question #10 : Model The Energy In Animals' Food

The diagram below shows an example of a food chain.

grass → caterpillar → frog → bass → osprey

Which conclusion can be made from this food chain?

Possible Answers:

The caterpillar transfers some of its energy to the grass.

The caterpillar transfers all of its energy to the frog.

The bass transfers some of its energy to the osprey.

The bass creates all of its own energy.

Correct answer:

The caterpillar transfers all of its energy to the frog.

Explanation:

The diagram presented is a typical food chain showing how energy flows from one organism to another. This food chain starts with grass, and when it is eaten, it passes energy to the consumer; in this case, it is a caterpillar. When the caterpillar is eaten, its energy is given to the frog and so on until it reaches the final consumer, the osprey. The cycle starts over again when the osprey passes, and decomposers break down the matter. So the conclusion that can be made from this food chain is that the caterpillar transfers all of its energy to the frog.
