snake

Question 11

What do the arrows represent in the diagram of a food chain?

Accepted Answer

The direction of energy flow through organisms

Answer

The order of size of organisms in the ecosystem

Answer

The importance of organisms in the chain

Answer

The energy increases as you move from left to right

Question 12

Which of the following statements best describes the flow of energy in the energy pyramid above?

Accepted Answer

Each group receives only a small amount of the energy from the level below it.

Answer

As you go higher in the pyramid, the amount of energy increases.

Answer

There is less energy in a producer level than a consumer level.

Answer

There is no energy above the level of producers in the system.

Question 13

Animals are consumers, meaning they need to eat food for energy because they cannot make their own. Which energy transformation is taking place when an animal eats food so it can keep warm?

Accepted Answer

Chemical to thermal

Answer

Mechanical to thermal

Answer

Mechanical to radiant

Answer

Radiant to chemical

Question 14

Why is it necessary to have sunlight-> in the equation shown below?

Accepted Answer

This process cannot occur without energy from the sun.

Answer

The arrow represents the specific direction of sunlight.

Answer

Sunlight uses carbon dioxide and water to make sugar.

Answer

It is not necessary.

Accepted Answer

Grass

Answer

Prairie Dog

Answer

Coyote

Answer

Soil Bacteria

Question 17

Reptiles do not have the ability to create their own heat, and instead, sit in the sun for long periods of time in the mornings to warm up. Mammals and birds, on the other hand, have the ability to create their own heat. Where do mammals and birds get the energy for this heat?

Accepted Answer

from food the animals eat

Answer

from oxygen they breath in

Answer

from sunlight the animals absorb

Answer

from body fat that keeps all heat trapped in the body

Question 18

Warm-blooded animals have the ability to shiver when they get into extreme heat deficiency. The muscles begin to move very quickly, causing the body to change its stored energy into other molecules.  During this process, heat is given off. What is the energy transfer that is occurring when an animal shivers?

Accepted Answer

chemical energy to thermal energy

Answer

thermal energy to chemical energy

Answer

mechanical energy to thermal energy

Answer

thermal energy to mechanical energy
