Answer 1

Answer:

then seed will not grow because seed will not get oxygen which is necessary for germination.

Answer 2

Explanation:

It depends on the seed. Some seeds need light to germinate. Some seeds don't have enough energy stored to push their sprout to the surface if they are too deep. Some seeds will still sprout and be ok but it might take a bit longer for them to show above ground.
