Does Apache httpd & Tomcat share same thread pool?

Question

I wanted to understand how do httpd and Tomcat use threads. If I connect Apache httpd and Tomcat with a AJP connector (mod_jk) then will they both share same thread pool and use individual threads OR httpd will first acquire a thread and invoke the servlet container in the same thread?

Thanks

No, they do not share anything but the word 'Apache' in their names.
