The correct answer would be DIFFUSION. The mechanism that controls water changes in the cells by the movement of water from an area of high water concentration to an area of low water concentration is called Diffusion. This mechanism continues until there is balance in the water concentration. On the other hand, Osmosis is the movement of water from an area of low water concentration to an area with high water concentration.
Autotrophic organisms are capable of synthesizing their own food and nutrition by harnessing sunlight and water.
Along with the entire kingdom Plantae and the following organisms are autotrophs:
Algae
Cyanobacteria
Seaweed
Phytoplankton
Fungi are heterotrophs, particularly of saprophytic nature. This means that they release enzymes on organic matter. These enzymes digest the organic matter into nutrients that the fungus can then utilize.
