How do i write a paragraph with 14 certain words

Write a paragraph on the assigned topic. then echange 14 of the words you have already used for 14 of your assigned words. make sure they all make sense though. add sentances or extra words if necessary. also make sure that your words you are exchanging have at least a similar definition. im assuming this is a vocabulary assignment.

This is what i found on google “phytoplankton, tiny organisms that live in the ocean, are autotrophs. some types of bacteria are autotrophs. most autotrophs use a process called photosynthesis to make their food.” i hope this you for what your looking for
