Energy from Animals' Food

5th Grade Science › Energy from Animals' Food
Which of the following best describes how a carnivore gets energy from the sun.
A grizzly bear sleeps all winter when it is mostly dark and cold outside, and then is active all summer when the weather is nicer.
A shark prefers to hunt in warmer water where seals and sea lions go in winter to give birth to their young.
A plant uses photosynthesis to get its energy from the sun, and then a deer gets its energy by eating the plant. Then when a wolf eats the deer, it receives energy from the deer.
Lions do much of their hunting at sunrise when nocturnal animals are ending their day and other animals are just getting their day started.
Explanation
Photosynthesis is the way in which plants convert the sun's energy into their own energy. And since animals get their energy from food, when an animal eats a plant it gets its plant-based energy indirectly from the sun, because that's how the plant itself got energy. Then when a carnivore eats a plant-eating animal, the carnivore gets energy from the herbivore, who got its energy from the plant, which got it from the sun. So even meat-eaters indirectly get their energy from the sun.
Which statement about the flow of energy in an ecosystem is correct?
Energy flows from the Sun to consumers.
Energy flows from the Sun to decomposers.
Energy flows from the Sun to producers.
Energy does not flow from the Sun.
Explanation
All nutritional energy comes from the Sun: plants use chlorophyll to photosynthesize the Sun's energy into plant energy, and then animals either feed on plants for that energy or they feed on the animals that have eaten that plant energy. The food chain begins with the Sun and then the energy flows to producers.
The diagram below shows an example of a food chain.
grass → caterpillar → frog → bass → osprey
Which conclusion can be made from this food chain?
The bass creates all of its own energy.
The bass transfers some of its energy to the osprey.
The caterpillar transfers all of its energy to the frog.
The caterpillar transfers some of its energy to the grass.
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.

Which object in the food chain would have an arrow coming from it, but no arrow going to it?
A plant
A grasshopper
The Sun
A lake
Explanation
All nutritional energy comes from the Sun: plants use chlorophyll to photosynthesize the Sun's energy into plant energy. Then animals either feed on plants for that energy, or they feed on the animals that have eaten that plant energy. An arrow would be facing outwards, displaying energy leaving the Sun and being consumed by a producer, but no arrow facing towards it because the Sun does not consume energy in the food chain.

Which of the following statements are correct?
Animals' energy is passed to plants.
Animals make their energy.
Energy flows from producers to consumers.
Some food chains only have predators.
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.
