I studied film & TV production at uni, and this was common knowledge and readily accepted even then.
The argument goes as follows: Reptiles eat insects. If you want to show a reptile catching and eating an insect, you have better control over framing, lighting and angles if that reptile is in a vivarium, than if it's out in the wild. Regardless of where it is, it would chow down on its prey in the same manner.
Where it all falls down, however, is when filmmakers set-up scenes to capture things that don't really happen in the wild.
The classic example was Disney's Oscar-winning 1958 wildlife documentary, 'White Wilderness'. The producers failed miserably in their quest to capture a mass lemming suicide on film. This is because lemmings don't really hurl tthemselves from cliffs. Also, The movie was shot in Alberta, Canada, where there are no indigenous lemmings. Lemmings were imported, and placed on snow-covered trolleys to create the illusion of a migration taking place. Once that sequence had been shot, the rodents were loaded into a bucket, taken to the edge of a cliff and hurled off the edge, while the camera team shot from underneath.
It doesn't just apply to wildlife documentaries. Check out Andrew Douglas' documentary, 'Searching For The Wrong-Eyed Jesus'. It's a documentary about the Southern States of America, taking music as its focus. There are some tremendous musicians on there, and some great performances. It's all shot in the style of a polished music video, though - but these musicians exist, this is their music, and they do live in this environment. The framing, editing and staging of the performance pieces are all measured, controlled and contrived, however.
I think it all comes down to the fact that it's sometimes more efficient and effective to deliver truth by means of a fiction... Legends, folklore, parables and religion, anyone?
