In ecosystems with more
the food webs and
interactions among living beings
more complex and diverse.
ecosystems environmental changes can
more easily compensated by
multiplicity of available resources,
and survival options.

In with less biodiversity the
are more dependent on
beings that serve them food
and they interact a small number
of species. In these
ecosystems abiotic factors are
restrictive the species are more
to such conditions and
sensitive to environmental changes.
even small environmental harm
cause big disturbances in
equilibrium of the ecosystem.
