LIFEE SYSTEMS - INTERACTIONS WITHIN ECO-SYSTEMS
INTRODUCTION
“The frog does not drink up the pond in which he lives.”
- unknown. And why would he? The frog, like every other animal and
plant depends on things in the pond which help to sustain him. In
turn, he provides things to other species who co-exist in that same
pond as an ecosystem. In the biosphere, there are many different
ecosystems. Each system is balanced between living and non-living
factors in a natural environment. The individual players within
each system have adapted to their environment. People are the only
players who change their environment, rather than adapt to it, to
make our lives easier. Farms replace forest, cities replace wetlands.
Our technology has sped our ability to alter the environment.
STUDENT DEMONSTRATION PROJECT
Interactions: Given a particular site at the Scenic
Caves, students will identify ecosystems that surround a particular
plant or animal.
Abiotic influence: Students will identify some
abiotic factors that are involved in the ecosystems found at the
Scenic Caves. They will then project what might happen if some of
the abiotic factors were changed.
Human impact: There are many types of plants at
the Scenic Caves that are threatened or in danger of extinction.
Choose an animal that is threatened. Research the major threats
and determine what can be done to help it survive. Consider food
supply, predators, habitat.
