<span>A light year refers to a very big amount of distance and is a measurement termed as an astronomical unit of measure. When you say that a galaxy is 5,000 light years away we are actually describing the speed of light within a year. One light year is actually equivalent to 9, 500, 000, 000, 000 kilometers. Just imagine how big or how far that galaxy is when you multiply those kilometers by 5,000?</span>

4. (a) Primary production is the production of carbon compounds from carbon dioxide, generally by photosynthesis. Study
Stels [109]

The graph is showing how primary production decreases as deep increases. It is due to the amount of available light in the water.

<h3>Primary production on the ocean</h3>

The primary production in the ocean is performed by microorganisms known as phytoplankton.

Phytoplankton populations are primary producers that include bacteria and algae, which use photosynthesis to produce biomass and release oxygen.

In a similar manner to plants, phytoplankton communities also contain chlorophyll in order to convert sunlight into biomass.

As ocean deep increases, the amount of available light in the water decreases, thereby also decreasing the primary production of the phytoplankton populations.
