This document presents a PowerPoint on ecosystems, highlighting the interaction between biotic (living) and abiotic (physical) components, their types, and functions. It discusses the importance of ecosystem management in maintaining balance and addressing degradation threats from human activities. The document emphasizes the need for adaptive management to ensure sustainability amidst increasing population pressures and resource limitations.

4.  Ecosystem or biocenosis is a
segment of nature/ biosphere
consisting of a community of
living beings and the
abiotic/physical environment
both interacting and
exchanging materials
between them.
 Ecosystem can be temporary
(e.g. rain water pond) or
permanent, natural or man-
made (e.g. aquarium,
agriculture), small or large.

5.  Biotic Components:
 They include all living beings
present in an ecosystem
producers, consumers and
decomposers. The components
are connected through food, its
contained energy and a web of
interrelationships.
 Abiotic Components:
 They include temperature, light,
wind/air current,
humidity/precipitation, water
and topography.

6.  Modification of the climate
 Maintenance of the hydrological cycle
 Erosion control and soil formation
 Maintenance of O- and N-Cycles
 Waste and toxic chemical treatment
 Pest Management
 Carbon storage; maintain the C-Cycle

7.  Increased population growth:
› Increasing our biotic potential.
› Decreased our environmental resistance.
 Contributions to ecosystem degradation:
› Introduce species
› Eliminate natural predators
› Alter abiotic factors
› Reduce biodiversity
› Misunderstand the role of fire
 Have we exceeded our carrying capacity?

8.  We need to protect and manage the natural
environment to maintain the goods and services vital to
human economy and survival.
 Establishing a balance between our own species and the
rest of the biosphere should be a practical goal for all of
us, if not also a moral goal.
 Adaptive Ecosystem Management: an approach that
accepts uncertainty of our knowledge base and flexible
to change as new information is gathered; the goal is to
balance our exploitation with an ecosystem’s capacity to
renew goods and services.

10. As the world’s population grows and natural resources
dwindle, the creation of parks and protected natural
areas is not enough to solve the problem of forest
destruction.
The farms, forests and tourism businesses with which we
work not only manage their own lands sustainably but
they also function as an integral part of the larger
landscape -- keeping trees standing, preventing erosion,
protecting waterways and soils, providing wildlife habitat
and reducing the risk of fires and other destructive
activities. Together, sustainably managed businesses and
neighboring protected areas can form a thriving mosaic
that nurtures ecosystems, wildlife and people.
