Question

Energy that is not passed on from one trophic level to the next is _______.
a. lost as heat
b. returned to the sun
c. destroyed
d. all of the above

Answer 1

i'm thinking d?

Answer 2

FAN AND MEDAL TO WHOEVER HELPS!!!

Answer 3

It is lost as heat

Answer 4

thank you!!! can you help me check a few more?

Answer 5

No problem and sure.

Answer 6

In the food chain shown, which of the following changes between trophic levels would have the highest energy conversion efficiency?

a. leaf to mouse
b. mouse to snake
c. snake to hawk
d. all changes would have the same efficiency

(ill post the pic of the food chain too)

Answer 7

but i'm thinking d?

Answer 8

Its D

Answer 9

which one? the one with the food chain?

Answer 10

I believe it would be A because every trophic level, 10% of the energy is lost. So, A would be the one to have the most energy.

Answer 11

But I might be reading the question wrong.

Answer 12

yah

Answer 13

The conversion efficiency from herbivores to carnivores is the least efficient of the tropic levels with an average conversion of _____.
a. 1 – 5%
b. 0.5 – 1%
c. 7 – 12%
d. 15 – 20%

Answer 14

that one i'm not sure on, but i was thinking b?

Answer 15

@SummerNS

Answer 16

It would be B I think. The one with the food chain is definitely A though.

Answer 17

Don't know this one, sorry ? :(

Answer 18

okay i just have a few more, do you mind helping check them?

Answer 19

How are gross production and net production different?
a. Net production is always greater than gross production.
b.Net production is always less than gross production.
c. Only animals have net production.
d. Only plants have net production.

Answer 20

this one i was thinking d?

Answer 21

It is d. Net Production is sunlight through photosynthesis so it's definitely d.

Answer 22

woohoo!! thank you :)

Answer 23

Why is a system’s work output limited?
a. Entropy decreases with each stage of a system, causing a decrease in available entropy to carry out each stage.
b. Systems tend to become less randomized over time, which causes spontaneous processes to no longer occur.
c. Energy is destroyed in each stage, causing the amount of available energy to decrease with each stage.
d. Energy is lost as heat in each stage, causing the amount of energy available to decrease with each stage.

Answer 24

this one i was thinking d?

Answer 25

c or d? i'm not 100% sure.

Answer 26

D

Answer 27

D I believe

Answer 28

ok and this one:

TRUE OR FALSE: Gross production is the amount of energy left after cellular respiration.

Answer 29

i was thinking true?

Answer 30

True

Answer 31

Which of the following levels is the most efficient at energy conversion?
a. producers
b. primary consumers
c. secondary consumers
d. tertiary consumers

Answer 32

this one i was thinking A?

Answer 33

I agree. I think it's A also.

Answer 34

Yup, its A

Answer 35

TRUE OR FALSE: Producers are the primary living source of energy in a food web.

Answer 36

i was thinking true?

Answer 37

Yup its True

Answer 38

Yes it's true.

Answer 39

Which of the following is the most likely flow of energy in an aquatic ecosystem?
a. phytoplankton ® fish ® zooplankton ® mammal
b. phytoplankton ® zooplankton ® fish ® mammal
c. zooplankton ® phytoplankton ® mammal ® fish
d. mammal ® fish ® zooplankton ® phytoplankton

Answer 40

thinking b?

Answer 41

Yes it's B

Answer 42

last one, true or false: Energy in an ecosystem flow from consumers to producers.

Answer 43

thinking false?

Answer 44

False

Answer 45

Energy flows from the bottom of the food chain to the top.

Answer 46

Tup, its False

Answer 47

Good Job @SummerNS
