U1 L3 Consumers Role-5th

The process that breaks down food into simple materials that an animal's body can use is called ____.

• Digestion
• circulation
• respiration
• photosynthesis

When an animal eats more food than it needs right away, its body

• changes all the food energy into heat.
• stores the extra food energy for later.
• releases all the energy so it does not get fat.
• converts the energy into sodium to use later.

When an animal dies, the once-living matter from the animal's body

• regenerates so the animal can live again.
• remains exactly the same for millions of years.
• is broken down and passes into the soil and air.
• disintegrates into small particles that eventually disappear.

Like other consumers, all of the food energy that humans use once came from the

• soil
• moon
• ocean
• sun

The gazelle is running from a lion that is chasing it. Where does the gazelle get the energy it needs to run?

• directly from sunlight
• from the food it eats
• from the wastes it produces
• from water it drinks

This monkey gets the energy it needs to climb trees by eating the tree's leaves. Where did the energy stored in the leaves come from?

• from the soil
• from the air
• from the sunlight
• from animals wastes

Some scientists traveled to Antarctica to study Adelie penguins. They weighed the baby penguins to see how much they grow every day. They found that the penguin chicks weigh about 86 grams when they hatch. But they gain about 100 grams of body weight each day until they are 50 days old. At that point, the chicks weigh about as much as their parents. What question can the scientists begin to answer by weighing the chicks?

• Where does the energy needed to grow their bodies come from?
• How well does a scale work in different parts of the world?
• How much energy do adult penguins need to survive?
• What foods are penguin chicks eating that help them grow?

This otter is eating a fish she captured in the river where she lives. Where does the otter store the energy from this meal in case she will need it weeks later when she cannot find food?

• It is stored in fat, because it is stored in for short periods of time.
• It is stored in fat, because it is stored in for long periods of time.
• It is stored in sugar, because it is stored in for long period of time.
• It is stored in sugar, because it is stored in for short period of time.

In many parts of the world, animal waste is used as a fuel source by people. This man in India is drying out cow dung patties. He will later sell them at the market as fuel for home cooking. Where does the fuel energy in cow waste come from?

• from the excess food that the cow stored in its body after digestion.
• from carbon dioxide gas the cow breathed out.
• from sugars in the bloodstream that are broken down for energy.
• from the plant material the cow ate but could not be used by the cow.

Consumers can use materials and energy from food to

• grow larger.
• stay warm.
• reproduce.
• all the above.
