Can someone answer this for me?

the supermassive black hole is in the middle of the galaxy.

yes it is weird but true

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.

it depends on how much it could carry.
