Rubrics:

In high biodiversity the risk
of damage from pest
infestation is minimized
leading to better income
due to the presence of
natural predators. Low input
of pesticides because
different pests feed on
different plants. Various soil
will be available to different
plants bec. Of the presence
of other organisms.
Organisms can feed on
different organisms, thus it
has a continuous supply of
food.Nutrient are recycled
and it can support more
organisms.
The higher is the
biodiversity the more stable
is the ecosystem.

Possible answer
Aedes egypti is the
carrier of virus that
caused dengue. The
female mosquito
bites animals and
people for it needs
blood for food. It
multiplies by laying
eggs which grow into
an adult mosquito
again, and repeat
the cycle.
