–
trade-offs- Any desired outcome (or advantage) that must
be given up when one option is chosen over another during a decision-making
process. Compromise decision when each choice involves both advantages and
disadvantages.
B. Record Homework notes in your science notebook:
1. Bringing a species into a
new environment can have consequences on how people and other organisms live.
Consequences means a big effect: intended or unintended (ex: extinction
of species, disease, social problems).
2. Organisms
are living things. Organisms can be classified (or grouped) by the
function (job) they serve in an ecosystem (ex: producer, consumer).
3. Species go extinct when
the environment changes and the species can’t adapt enough (or quickly enough)
to survive.
4. When an area becomes
overpopulated, the increased use of resources will degrade the environment.
5. Making decisions about
complex issues often involves trade-offs—giving up one thing to gain another.
