This question is quite unusual if you ask me ... So, um, why would you ask this? Maybe crouched...
Possibly because it is constipated. It depends on the type of animal and how long it has gone without excreting, but I would ask a vet, if possible. I knew a calf once that died of constipation.
because they live in deserts where there is no water and when they drink water 120 gallons because when we don't drink water we get constipation or dehydration the same way even camels do so they excrete in the form of hard-pellets
no, clouds not excrete
yes plants do infact excrete
Ferrets excrete to get rid of waste
Yes. All animals excrete.
All living things excrete.
Lungs excrete carbon dioxide and kidneys excrete urea and other substance
animals have to excrete to remove wastes from their body
Yeast excrete CO2 after they undergo respiration.
They excrete faeces and uric acid from their cloaca.
I think that some types of jellyfish dont excrete.
