Answer:
After being changed into adjectives, the words become:
1. productive
2. imaginative
3. endangered
4. organised
5. acknowledged
Explanation:
The original words were all verbs: produce, imagine, endanger, organise, and acknowledge. As we can see, in order to transform them into adjectives, we needed to add suffixes to them. A suffix is a group of letters placed at the ending of a word in order to change it into a new word. Above, we used two suffixes: -tive and -ed.
produce - productive
endanger - endangered
