I used the powerpoint with a class and liked the straight forward approach and clear images. However I edited it to include Energy loss via Faeces & Urine rather than just "Excretion". I also edited the spelling on a slide to Detritivores. Overall I really liked this short pp and will use it again.

My class liked as it summarizes nicely the topic
This was easy to follow and highlighted how energy is lost as it flows through the ecosystem
