Carbon get recycled by the use of human and animals they inhale it.
Plants obtain carbon from the atmosphere by breaking CO2 apart and releasing the oxygen during photosynthesis. Animals eat the plants, excrete an undigested portion of the carbon, and exhale the rest through respiration of the carbon with atmospheric oxygen (or in the case of marine animals--oxygen dissolved in water).

One is a dolphin. Whales also I think.
the equipment used is a boat , office and animals

The answer is INSECTARIA They study Ents.
