Yes. The lancelet (or amphioxus) is a fish-like invertebrate sea creature. The creatures (subphylum Cephalochordata) are sometimes harvested as human and animal food.
Water is lost from the gas exchange surface of terrestrial organisms because gases must be exchanged with air. Terrestrial organisms have a high water potential, therefore when the gas exchange occurs water will be lost.
Manometers can be used to record metabolic gas exchanges of any kind. Measurements of the gas exchange can be recorded using a respirometer as well.
cutaneous gas exchange
There is definitely a relationship between an animal's gas exchange system and the environment. The animal gives the plant carbon dioxide and takes oxygen from the plant.
The gas occurs by simple diffusion through the cells.

in the leave
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
in their gills.
In the alveoli
--it is in the alveoli where the exchange of gases occur.. :))
