WAEC Biology 2015 Theory — Question 5

Model answer

Tapeworm is an endoparasite. It absorbs already digested food from the host (through its entire body surface), which explains why it lacks a digestive system of its own. In the gut of man, the tapeworm uses its hooks and suckers only to hold/attach itself in position (not to feed - it does not use suckers for sucking food).
