The video uses the term Chemosynthesis to describe how Riftia pachyptila is the primary producer in this deep sea ecosystem. This implies that the overall organism (Animal, symbiotic bacteria, and endosymbiotic bacteria) produce reduced organic carbon compounds through chemolithoautotrophy. You may need to investigate this a bit, but explain how carbon fixation occurs in this organism.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
