enriched by the vegetal covering made
of leaves and branches ttrees. Deforestation reduces thishat fall from the
enrichment. In deforestation zones the
rain falls directly on the ground causinerosion, “washing” large areas g
(leaching) and contributing to make the
soil even less fertile. Besides tdeforestation disallows the recycling hat, theof (^)
essential nutrients for plants, like
nitrogen. In this manner those regionsand their neighboring regions undergo
desertification.
- How can a great biological
diversity protect an ecosystem
from environmental damage?
Why are less biodiverse
ecosystems at risk of suffering
deep biological harm if
submitted to even small
changes?
In ecosystems with more biodiversity
the food webs and ecolointeractions among living gicalbeings are (^)
more complex and diverse. In these
ecosystemsbe more easily compensated environmental chaby thenges can
multiplicity of available resources, foods
and survival options.
In ecosystems with less biodiversity the
individuals arsome beings that serve them as foode more dependent on (^)
and they interact with a small number
of different species. Iecosystems generally abiotic factorsn these (^) are
restrictivespecialized to and the species are moresuch conditions and more (^)
sensitive to environmental changes. So
even small environmental harm can
cause big disturbances in the
equilibrium of the ecosystem.
- Is monoculture a system
that contributes to great
biological diversity of an
ecosystem?
Monoculture means that in a large area
a single crop (only one species ois cultivated. Therefore monoculturef plant)
does not contribute to the formation of
a commspecies in tunity with ghe area. Since reat variety othere is only af (^)
single type of producer the types of
consumers that can also restricted. live in the area are
- What are some economic
applications that can be
generated by very biodiverse
ecosystems?
Very bioeconomic pdiverse otential. Tareas phey can resent enormousbe a
source of raw material for the research
and production ochemical products and food. They aref medicines, cosmetics,
depositories of genetic wealth that can
be explored by biotechnology. They aresources of species for agriculture. They
can also be explored by 'ecological
tourism'.
