Food-eating

Answer

Sunlight

Answer

Energy

Question 5

In a trophic pyramid, which level contains the most energy?

Accepted Answer

Producers

Answer

Tertiary consumers

Answer

Secondary consumers

Answer

Primary consumers

Question 6

How does the concept of a trophic pyramid help in understanding energy flow in an ecosystem?

Accepted Answer

It illustrates that energy decreases as it moves up the trophic levels.

Answer

It shows that energy is evenly distributed among all trophic levels.

Answer

It indicates that energy increases as it moves up the trophic levels.

Answer

It demonstrates that energy is only present at the producer level.

Question 7

Which of the following best explains why energy decreases at each successive trophic level in a food chain?

Accepted Answer

Energy is lost as heat due to metabolic processes.

Answer

Energy is destroyed as it moves up the trophic levels.

Answer

Energy is converted into matter at higher trophic levels.

Answer

Energy is stored indefinitely at each level.

Question 8

Predict the consequences of a decrease in producer population on the trophic pyramid.

Accepted Answer

The entire pyramid would collapse due to lack of energy.

Answer

The number of decomposers would increase.

Answer

The biomass of primary consumers would increase.

Answer

The energy flow would remain unchanged.

Question 9

Which of the following best describes a trophic pyramid?

Accepted Answer

A representation of the biomass at each trophic level

Answer

A diagram showing the number of organisms at each trophic level

Answer

A chart of the energy flow in an ecosystem

Answer

A list of all species in an ecosystem

Question 10

Identify the role of producers in the trophic pyramid.

Accepted Answer

They convert solar energy into chemical energy through photosynthesis.

Answer

They decompose organic matter.

Answer

They consume other organisms for energy.

Answer

They store energy in the form of fat.

Question 11

Analyze the impact of removing a top predator from a food chain.

Accepted Answer

It would lead to an overpopulation of secondary consumers.

Answer

It would increase the number of producers.

Answer

It would decrease the population of primary consumers.

Answer

It would have no effect on the ecosystem.

Question 12

Which of the following best describes the term "trophic level"?

Accepted Answer

The position an organism occupies in a food chain

Answer

The total biomass of an ecosystem

Answer

The rate of energy transfer in an ecosystem

Answer

The diversity of species in an ecosystem

Question 13

What happens to the other 90% of energy when it is passed up the food chain?

Accepted Answer

it is used for metabolic processes or given off to the environment as heat

Answer

it is found in the dirt

Answer

it us used for swimming

Answer

it is used to make a Krabby Patty

Question 14

Which organism in this food chain is a producer?

Accepted Answer

Grass

Answer

Fish

Answer

Grasshopper

Answer

Hawk

Question 15

If the hawks suddenly disappeared, what could we expect to see happen to the other trophic levels?

Accepted Answer

We'd expect the frog population to increase, causing the insect population to decrease, causing the plant population to increase.

Answer

We'd expect the frog population to decrease, causing the insect population to increase, causing the plant population to decrease.

Answer

We'd expect to see the pyramid remain about the same, since only the top part was taken and not a part farther down and more important.

Answer

We'd expect to see the pyramid completely collapse, since the top was taken and that makes it the most important part, since that's where all of the energy comes from.

Question 16

Which is the likeliest outcome if an apex predator goes missing?

Accepted Answer

Their prey's population will be out of control, causing issues for all trophic levels.

Answer

The population of all other organisms will decline.

Answer

The population of all other organisms will increase.

Answer

Producers will rapidly decline.

Question 17

Extra Credit Question: Say some plants are being eaten by grasshoppers, mice, rabbits, caterpillars, and deer. Then suddenly the deer all leave or are wiped out by a disease.
What will happen to the other primary consumers?

Accepted Answer

The other primary consumers will have a little less competition and their populations should increase.

Answer

This will cause a trophic cascade among the primary consumers.

Answer

The other primary consumers will become secondary consumers.

Answer

The other primary consumers will not be effected because they are all in the same trophic level as the deer.

Question 18

Which term best fits this definition?"An organism that eats plants"

Accepted Answer

primary consumer

Answer

producer

Answer

secondary consumer

Answer

10% rule

Question 19

A trophic pyramid is a model that shows...

Accepted Answer

how much energy flows from one level to the next in a food chain.

Answer

how many organisms can exist in a single food web.

Answer

how much total energy and matter exists in a single ecosystem.

Question 20

Which of these trophic levels has the most energy?

Accepted Answer

First stage consumers

Answer

Second stage consumers

Answer

Third stage consumers

Question 21

In a trophic pyramid, which level is responsible for converting solar energy into chemical energy?

Accepted Answer

Producers

Answer

Primary consumers

Answer

Secondary consumers

Answer

Tertiary consumers

Question 22

Which of the following best describes the energy transfer efficiency between trophic levels in a trophic pyramid?

Accepted Answer

10%

Answer

1%

Answer

25%

Answer

50%

Question 23

What is the primary reason for the decrease in biomass as you move up the trophic levels in a trophic pyramid?

Accepted Answer

Energy is lost as heat during metabolic processes

Answer

Biomass is converted into energy

Answer

Organisms at higher levels are smaller

Answer

Producers have less biomass
