Question

Antartica is the coolest , driest continent on Earth, and only a few species survive i's harsh elements. Yet scientists have found fossils of green fern plants n Antartica. Based on these findings, which of these is the best conclusion?
1.The climate of Antartica changed over time.
2.The Location of Antartica has always been at the South Pole.
3. These fossils are of an organism that adapted in Antartica over time.
4. This species could currently exist in Antartica if there was less competition.

Answer 1

What do you think the answer is?

Answer 2

To be honest I think it's A in my opinoin

Answer 3

Good choice. Let's look at each of the possible answers.

Answer 4

Okay!

Answer 5

A seems logical so far... The climate in Antarctica has changed over time.

Answer 6

B, however...

Answer 7

I don't know much about the South pole

Answer 8

The location of where Antarctica is does not have anything to do with the south pole. Antarctica is in the South Pole, but that doesn't really change anything else.

Answer 9

C seems slightly reasonable, but, if the plants changed over time, wouldn't they most likely still be around today?

Answer 10

Yes they would but would there be more if the plants changed over time?

Answer 11

Wouldn't*

Answer 12

There would be more if the plants changed over time.

Answer 13

Due to natural selection, traits in different species' DNA adapt to the environment. The species that aren't ready for that specific area don't survive, and eventually go extinct.

Answer 14

D is also somewhat reliable, but...

Answer 15

Ohhhhhhhhh

Answer 16

So it's like a cycle?

Answer 17

With trees that are packed within one another, there would be competition.

Answer 18

Like people we die but then comes a new generation

Answer 19

It is sort of a cycle.

Answer 20

of other people

Answer 21

I made a diagram of it.

Answer 22

Like how the wooly mammoth couldn't survive a warm world. They were meant for the Ice Age.

Answer 23

0-0

Answer 24

I thought they were meant to be there

Answer 25

They survived during the Ice Age, but couldn't survive after it was over.

Answer 26

4. This species could currently exist in Antartica if there was less competition.

Answer 27

This answer doesn't really make that much sense.

Answer 28

There wasn't that much competition... they were only smaller plants.

Answer 29

Also, something would have survived competition IF THE COMPETITION even happened.

Answer 30

Okay I have 2 thought
1.a I think it's A because when climat changes there becomes new growth and old growth goes away and does it over and over and over again
2. I think it might be D becuase like anmals might eat the plants? or humans come into Antartica and observer the plants

Answer 31

Well, they are fossils. At least thousands of years old.

Answer 32

Sorry I typed so slow I had a few typoes

Answer 33

Yes

Answer 34

Based on the info, I would say A.

Answer 35

Also, there weren't really any animals.

Answer 36

P bears seals apenguins and i gues that's all

Answer 37

If there were animals, the question would also have a better chance of saying "green fern plants AND animals."

Answer 38

And fish

Answer 39

I am not sure if they would go that far north/south, however.

Answer 40

Even polar animals have their limits, lol.

Answer 41

Yes so Answer is A in mine and your opinion?

Answer 42

In my opinion, the other answers make less sense.

Answer 43

Yes indeed

Answer 44

So A is the best way to go!

Answer 45

let me know if it is right/wrong! Have a good day!

Answer 46

thank you sorry I had to chop limes ;(

Answer 47

But thank yo so much for spending 25 or more minutes of your time with helping me it really meant alot!!!
