Ecosystems are fragile. She explained that an ecosystem is like a plane. "If you start taking parts of out of the plane, it may continue to fly, but eventually it will crash."
The word "ecosystem" is derived from the Greek terms "oikos" and "sistema". Oikos means habitat. Sistema means a set of interacting components arranged neatly to work together for some purpose. Essentially, an ecosystem is a habitat made up of living and non-living things that work harmoniously together to produce energy and eventually attain sustainability. The arrangement of the ecosystem is like a clock where each part works closely and in harmony with each other such that it is able to tell time.
"A healthy marine ecosystem is like a well-oiled machine. When all of its parts are intact and working, the ecosystem can provide important goods and services, such as livelihoods, protein-rich diets, waste water epuration and coastal tourism. When the machine breaks down, due to overfishing, the benefits it provides are lost."
"An ecosystem is like an interest-bearing bank account. Leave it alone, and it will replenish itself. Draw it down to accelerate growth, or slow growth a bit to help it replenish itself faster. Run it down to zero though, and you can go from "decent enough" to "death spiral" overnight. Ecosystems have discontinuities – one can extrapolate linearly... until one no longer can."
"An ecosystem is like a giant, natural recycling machine "
A lesson plan is linked.
An ecosystem is like a complex self-perpetuating machine.
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
