Insects provide several important ecosystem services including pollination, pest control, decomposition, and as a food source. They play a key role in pollinating about 98% of flowering plant species, including 75% of the top 100 crop species that produce most of the world's food. Insects such as beetles, flies, ants, and termites help break down dead plant matter and waste, regulating decomposition. Dung beetles in particular help decompose manure, preventing the loss of nitrogen into the atmosphere which contributes to global warming. Many insect species also feed on other insects, helping to naturally control pest populations.

2. Insect comprise the most diverse group
of multicellular organism in the planet
earth, which provide several ecosystem
services like pollination , pest control (
bio-control) ,decomposition ,transference
of energy through food chain.

3. Insect play an important role in
the production of plant species
about 1 lakh pollinator species
have been identified out of which
98% are insects.

4. Over 90% of 2 lakh 50 thousand
flowering plants species depend on
pollinators .This is applicable for
75% of the hundred crop species
that generate most of the worlds
food grain.

5. The process of waste biodegradation
is regulated and controlled by the
insect community. Beetle , larve ,flies
,ants and termites clean up dead
plant matters and break them into
tiner particles for further
decomposition by microbial
community.

6. Dung beetle ( About 4000 species
documented) also play a significant
role in decomposing manure .If the
dung remains on the soil surface
about 80% of the nitrogen (N2) is
lost to the atmosphere which is one
of the prime causes of global
warming.

7. The number of insect that feed or
prey on the other insect is vast.10%
of all insects are parasitodis .

8. Entire order of insects such as
Odonata ( Dragonflies) and
Neuroptera ( Net-winged insects
such as lacewing and ant lions) are
predators.
