what should i write , i drew the two buildings with smoke and wrote on the side “never forgotten.” Pls help:/

Well just say

Explanation:

The smoke symbolizes the last thing majority of the passengers had seen after they crashed into the twin towers. The smoke symbolizes the chaos that erupted once the first twin tower had went down. The " never forgotten " symbolizes how many lives were lost, and how would continue to impact those who weren't even here or involved like it continues to impact us today. The never forgotten symbolizes the mourning and the coming together of the families who lost a friend, family member, or someone close.

food chain i would say only because there is competition on getting food and survival
