Answer 1

temporary ecosystem are short lived while permanent are long lived...

Answer 2

Crop lands, fish ponds and aqua ponds are temporary ecosystems because they are artificial or man-made in nature.

Most of these dry up during the dry spells or drought and famines. These might also be claimed back by man due to economic purposes, like agriculture or housing purposes.

Sometimes the ponds are also used as waste discharging sites. This makes the ecosystems unrelaible for long term use.
