Bony fish belong to Class Osteichthyes, while cartilaginous fish belong to Class Chondrichthyes. Bony fish have a bony skeleton, while cartilaginous fish have one composed mostly of cartilage. Bony fish have body coverings of scales, while cartilaginous fish are covered with dendritical projections (think shark skin).
Bony fish are found in fresh and salt water; cartilaginous fish are found only in salt water. Bony fish have gills covered by an operculum; cartilaginous fish have gill slits. Bony have no eyelids; the cartilaginous fish do. Bony fish have an air-filled swim bladder; cartilaginous fish have an oil-filled liver to keep them bouyant. Hope this helps! Whew!

Scrubbers is another name for Flue gas desulfurization equipment. Flue gas desulfurization equipment reduce the impact of coal use by removing sulfur dioxide in flue gas from fossil-fuel power plants and from the emissions of other sulfur oxide emitting processes. Power plants use flue gas desulfurization equipment to remove impurities such as sulfur, nitrogen oxides and other particulates from smoke before it goes away from their smokestacks.
Anything about the same as 2,000 kilocalories.
If the producers are plants / algae, and contain 2,000 kilocalories of energy, the primary consumers, which are the ones eating the plants / algae will obtain about the same amount of energy the producers originally have.
