Species diversity

Explanation:

In order to assess the species diversity of a community, one would need to know the number of different species present as well as the relative abundance of the different species

Species diversity is a function of species richness, the number of species in a given locality and species evenness, the degree to which the relative abundances of species are similar The composition of species in a given ecosystem is the result of long lasting evolutionEach species has adapted to its own niche, which is characterized by certain features (e.g. temperature range, availability of food or light) enabling the species to reproduce and thus maintain its populationThe loss of one species affects many other species and causes imbalanceAs a result, several functions within and of the system are not carried out any moreAny species that will take over the lost specie's niche will most certainly not replace all of the functions it used to perform

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
