Change of biotic components in our eco-column

Our fern has grown 4mm since we planted it and our mint has grown 2mm since we planted it. Most of our animals are still alive but unfortunately one earthworm has died and a couple of wood lice have also died. Our two earthworms are situated deep around the side of our Eco-column, we have 6 wood lice left and lots of termites, we can't count them because there are too many.
