Ecosystems
An ecosystem (EK-oh-sis-tuhm)
is made up of groups of living things, and the environment in which they live.
In an ecosystem, the living things are able to get the things that they need in
order to survive. Healthy ecosystems are in balance. In other words, there is
enough food, water, and shelter for all of the species that live within the
ecosystem.
Ecosystems are made up of
several different populations. A population is a group of the same species of
plant or animal living together in the same place and time.
Plant and animal populations
interact with each other in many different ways.
When plant and animal populations
work together, they function as communities. A community is made up of all the
populations found in a specific area.
There are many different
types of ecosystems. Ecosystems can be found in tropical rain forests,
saltwater marshes, coral reefs, kelp forests, and deep in the ocean. Each
ecosystem is unique, but each also requires a delicate balance between the
plant and animal species in order for the ecosystem to remain healthy.
Pollution, rapid deforestation, natural disasters, and slow environmental
changes over time can all threaten the health of our earth's ecosystems. We
should do everything we can to preserve nature's delicate balance so that its
wonders can be enjoyed by generations to come.
