Warm surfaces in tropics
affects of warm water

Some fish eggs
need warm water
embryos need about 12°c or higher
warm water fish use a lot of energy
body requires more food and energy
eat plants and other small animals
The surface and coral reefs provide plentiful meals
temperatures affect quantity and quality
enzymes work better in warm temperatures
-a substance produced by a living organism that causes a specific biochemical reaction.
-the chemical processes that occur within a living organism in order to maintain life.
Contact with a Cold Environment
Metabolism rates slow down
warm water fish eggs die
little fish activity
Cold Surfaces in the polar regions
affects of cold water
-slow growth rates
-lower oxygen levels
-low energy requirement
molecules transfer slowly between cells
enzymes slow down in cold temperatures
Low Oxygen Levels
Dissolved oxygen amount indicates life possibility
breathe by absorbing dissolved oxygen through gills
photosynthesis releases oxygen into water
Slow and Steady Lifestyle
less food consumption
less energy required
Contact with Warm Water
fish catch diseases and toxins easily
cold water eggs die
fish will disappear or be replaced by other fish
