4. What are BIORESOURCE?
• Non fossil biogenic resources
• Used by humans for multiple purposes:
1. to produce food,
2. substantial products,
3. energy carriers.

6. Categories
Primary bioresources
• Generated for specific
application-oriented
purpose in forestry,
Agriculture, aquaculture.
• Example:wood, grain, potat
o, bamboo, algae.
• Not all plants can be
considered as a primary
bioresources.
• Generated during primary
processing In industrial
processing as by- products
or residues During
maintenance of large green
areas.
• Example :- fruit residues
• low amount of impurities,
and they are produced in
large quantities
Primary bioresource Secondary bioresources
Types of bioresources

7. • Occur as residues in small
amounts at the generation
place which are Not
genuine.
• Shows Uncontrolled
modifications.
• Example:-Degradation
during storage, may have
taken place.
• Occur after a product is
used and can be
distinguished according to
the time frames of their
generation after start of
utilization into short-, mid- ,
and long-term categories.
• Examples:- wood
construction materials.
Tertiary bioresources Quaternary bioresources

9. What is biodiversity?
• Biodiversity:-describes the richness and variety of
life on earth. It is the most complex and important
feature of our planet. Without biodiversity, life would
not sustain.
• The term Biodiversity was first coined by Walter G.
Rosen in 1986.
• Biodiversity represent the sum total of various life
forms such as unicellular fungi, protozoa, bacteria,
and multi cellular organisms such as plants, fishes,
and mammals.

Types of biodiversity

12. Types of Biodiversity
• Genetic diversity -the total genetic information
contained in the genes of all species.
• Species Diversity- The variety of species, refers to the
number of species and the number of individuals in a
species.species diversity are divides into two sub parts.
• Species richness:-is simply a count of species, and it
does not take into account the abundances of
the species or their relative abundance distributions.
• Species everness:- refers to how close in numbers
each species in an environment is.
• Ecosystem Diversity - the variety of habitats natural
communities and ecological processes.

13. Uses of Biodiversity
1.Source of food and improved varieties:-There are nearly
80,000 species of edible plants. 30 species are mostly used as
major source of food and 85% of the world’s food production
is met by cultivating less than 20 plant species.
• (e.g. wheat, rice, maize, sugar cane)
2. Drugs and Medicines:- are manufactured from various
chemicals such as alkaloids, resins, fatty acids, glycosides,
essential oils are obtained from medicinal plants. Ayurvedic
medicines available in the market for treating numerous
diseases in man are based on plant products.
3. Fibres:-Fibre yielding plants such as cotton, flax, hemp, jute,
etc. are the major sources of fibres. More and more varieties of
plants are being explored for obtaining superior fibres.
4.Useful products:-large number of useful products such as
gums, dyes, rubber, tannins, latex, paper, tea, coffee, perfumes,
waxes and dry fruits. Similarly, animal species provide wool,
fur, skin, leather, honey, lac, silk, waxes, pearls, horn, antlers
etc.

14. 5. Ecosystem Services:-such as replenishing oxygen
through photosynthesis, pollination through bees,
regulation of global climate, control of flood, and soil
erosion, nutrient cycling”, microbial waste treatment,
biological control of pests etc.
6. Ecological Balance:-Biodiversity of species enhance
ecological balance(e.g. large scale killing of snakes
will increase population of rats and hence large scale
destruction of crops.
7. Ecosystem stability, productivity and health:-
Biodiversity is essential for stability of an ecosystem.
Communities having more species tend to be more
stable than those with less species.

15. Conservation

16. Conclusion
• Biodiversity is our life. If the Biodiversity got lost at
this rate then in near future, the survival of human
being will be threatened. So, it is our moral duty to
conserve Biodiversity as well our Environment. Long-
term maintenance of species and their management
requires co-operative efforts across entire
landscapes. Biodiversity should be dealt with at scale
of habitats or ecosystems rather than at species
level.
