<h2>Availability of Plankton</h2>
Explanation:
- The term plankton comes from the Greek derivative planktos, meaning wandering. Organisms in this group spend either part or all of their life in a drifting state, with no ability to swim against a current. Most have little or no ability to swim at all. Though some are larger, most planktonic creatures are microscopic and make up the bottom of the food chain in aquatic environments
- Plankton can be divided into two categories: phytoplankton are those organisms that are plant-like, and zooplankton are organisms that are animal-like. Interestingly enough, many planktonic species are neither plant nor animal but are creatures that belong to the kingdom Protista
- Zebra muscles are found in water bodies which attached to pipes and other surfaces of water supply to impliment the availability of plankton
 
        
        
        
Answer: Minerals 
Explanation: The body decomposes and after about 40 to 50 years bones are mostly brittle and dry with no traces of flesh. After thousands of years bones also disintegrate (decay) leaving brittle mineral frame. The life of bones is determined by the soil type its buried in, nuetral soils takes longer then acidic soil condition.
In this case osteocytes(bone cells) are the first to decompose followed by the cartilage and bone marrow, leaving behind mineral traces that scientist can study after thousand years.
