Question

Which statement describes the relationship between the lizard and the frog on the food web?

a. Heterotrophs supply food for the autotrophs.
b. Autotrophs supply food for the heterotrophs.
c. Heterotrophs compete for the same food source.
d. Autotrophs and heterotrophs share the same food source.

Answer 1

i dont think they eat the same thing, do they? I think its B

Answer 2

I don't think it's B. B is a true statement, but the question asks you for a specific statement about the relationship between the frog and the lizard, not some general truth from the world of biology.

Well you know that heterotrophs are organisms which consume 'complex' molecules and autotrophs are organisms which consume very simple molecules, like carbon dioxide.

Which are the frog and the lizard?

Then you ask yourself, do they supply food for autotrophs? No. Autotrophs feed on very simple compounds, while frogs and lizards are not simple. So option A is out. Then you ask yourself, do frogs and lizards compete for the same food source, and according to the food web, they do.

So which do you think the right answer will be?

Answer 3

well i dont think they do, doesnt the snake eat them both, but they dont eat the same things, right?

Answer 4

The frog and the lizard are both heterotrophs, agreed?

In terms of answering the question, that means the right answer is either A or C. A is plainly ridiculous: heterotrophs do not supply food for autotrophs, so we suspect the right answer will be C.

So then we look at the picture. The picture shows that both frogs and lizards eat insects. Which means that, yes, indeed they do compete for the same food source.

So from that, I think the answer is definitely C.

Answer 5

so the food source is indicated by the red arrows?

Answer 6

Yes, I think so.

Answer 7

oh okay thats what confused me, thank u so much

Answer 8

i think b

Answer 9

i dont need this one anymore, go to the question im on, ok?
