Well, it doesn't happen in plants or bacteria, if that's what you're asking. :P
It can happen to humans too.
Cat lip or the Harelip is a disease called Cleft lip (cheiloschisis) or cleft palate (palatoschisis). However they can occur together as Cleft lip and palate.

Ecosystems do not have organs. Organs only occur in individual living animals.
chloroplasts, because photsynthesis only occurs in plants, not animals
Photosynthesis only occurs in plants, on the leaves, to produce nutrients for it. Animals all respire, which is effectively the opposite of respiration.
Photosynthesis occurs in the chloroplasts of plant cells and does not occur in animals.
Milk teeth would, by definition only occur in mammals, since mammals are the only animals that produce milk for their young. Other animals may well have a set of deciduous teeth that are replaced by adult teeth as they mature.
Photosynthesis does not occur in animals. It is a process that takes place in plants, algae, and some bacteria, where they convert sunlight into energy. Animals obtain energy through consuming plants or other animals.
Cleft palate is also known as palatoschisis or palatine cleft. It refers to a congenital condition characterized by an opening or gap in the roof of the mouth (palate) that can occur along with a cleft lip. Other terms may include "orofacial cleft" when referring to conditions affecting both the lip and palate.
It is unknown how many ligers exist today. These animals only occur in captivity and estimates range from between 10 and 100.
No of course not. It's physically impossible.
