They vary in their habit and behaviour, shapes, sizes and colour.
The remarkable diversity of living organisms form an inseparable
and significant parts of our planet
however, the ever increasing human population is posing serious
threats to bio-diversity.

Know that all the three sample areas are represented by three
kinds of species. (species richness is same).
However they vary in species abundance varying number of
individuals per species and in taxonomic diversity.
Observe that sample C has the highest species diversity as it is
represented by taxonomically unrelated species}
No need to memorize line by line, this slide is for your understanding
The different sample areas showing species richness (sample area 1),
species evenness (sample area 2) and
diversity due to unrelated species (sample area 3).

3. Ecosystem diversity
(i) -Diversity:
It tells the species diversity in a given community.
It depends upon species richness and evenness.
(ii) -Diversity:
It describes a range of communities due to replacement
of species which arises due to the presence of different
microhabitats, niches and environmental conditions.
(iii) -Diversity:
It describes diversity of habitat over a total land escape
or geographical area.
At least 40 per cent of the worlds economy and 80 per cent of the needs of
the poor are derived from biological resources.

Bees are vital to bio diversity. There are 130,000 plants for example for
which bees are essential to pollination, from melons to pumpkins,
raspberries and all kind of fruit trees as well as animal fodder like
clover.
As just one small example, some spiders can produce their silk with
a higher tensile strength than many alloys of steel even though it is
made of proteins. So biologists are looking at these processes in
more depth to see if they can reproduce or enhance such
capabilities.
