A broad ppt on the topic biodiversity. Suitable for middle and high school students. Good for understanding the importance of biodiversity.

2. Biodiversity is the variety of life forms on
earth and the essential interdependence of all
living things.
It is a term used to describe the enormous
variety of life on Earth. It can be used more
specifically to refer to all the species in one
region or ecosystem. Biodiversity refers to
every living thing, including plants, bacteria,
animals, and humans.

4. Biodiversity provides food for
humans. A significant
proportion of drugs are
obtained. A wide range of
industrial materials like
cotton, dyes, gums, rubber,
and oil are derived directly
from plants.
It plays an important role in
making and maintaining
ecosystems.
Biodiversity provides
functioning ecosystems that
supply oxygen, clean air and

5. It
is necessary to classify organis
ms because it helps in the
identification of living
organisms as well as in
understanding the diversity of
living
organisms. Classification help
s us to learn about different
kinds of plants and animals,
their features, similarities and
differences.
The goal of classifying is to
place an organism into an
already existing group or to
create a new group for it,
based on its resemblances to
and differences from known
forms. To this end, a hierarchy
of categories is recognized.

6. All organisms are divided into five kingdoms. Living organisms are
classified on the similarities, each kingdom is further divided into
smaller taxonomic categories in the following way:
This table is also known
as a taxonomic
hierarchy

7. The core threats to
biodiversity are human
population growth and
unsustainable resource use.
To date, the most significant
causes of extinctions are
habitat loss, introduction of
exotic species, and
overharvesting. Climate
change is predicted to be a
significant cause of
extinctions in the coming
century.

8. I’ll conclude that biodiversity is very
important for us as it is a source of food
and income. Every ecosystem on earth
needs biodiversity and without it the whole
web of life that includes us
humans will collapse. Species provide
important resources so we can survive.
The ocean and biodiversity need each
other without biodiversity the
ocean would be murky with no sign of life.
