Phytoplankton is responsible for about 70% of the oxygen released into the atmosphere. true false

This is false. The phytoplankton do acount for much but 70% is too much. The precise numbers would be around 50%, while the rest is produced by regular plants found on earth, with a large number coming from the Rainforests that are dense and unfortunately often destroyed by humans, even though we need them.

Cand d are correct because the rest are just showing your mistakes and you don’t want people who are reading a summary you wrote to see all the mistakes you made.
