Questions and Answers 100% Pass
Sustainability -
CORRECT ANSWER: Ability of the earth's various systems, including
human cultural systems and economies, to survive and adapt to
changing environmental conditions indefinitely.
QUESTION: Environment -
CORRECT ANSWER: All external conditions, factors, matter, and
energy, living and nonliving, that affect any living organism or other
specified system.
QUESTION: Ecology -
,CORRECT ANSWER: The biological science that studies how living
things interact with one another and with their environment; study of
the structure and functions of nature.
QUESTION: Organism -
CORRECT ANSWER: Any form of life
QUESTION: Species -
CORRECT ANSWER: A group of organisms that has a unique set of
characteristics that distinguish it from other groups of organisms; a set
of individuals that can mate and produce fertile offspring.
QUESTION: Ecosystem -
CORRECT ANSWER: A set of organisms within a defined area of land
or volume of water that interact with one another and with their
environment of nonliving matter and energy.
,QUESTION: Environmentalism -
CORRECT ANSWER: A social movement dedicated to trying to
sustain the earth's life-support systems for all forms of life.
QUESTION: What are the three goals of environmental science? -
CORRECT ANSWER: 1.) To learn how life on the earth has survived
and thrived.
2.) To understand how we interact with the environment.
3.) To find ways to deal with environmental problems and live more
sustainably.
QUESTION: What are the three principles of sustainability? -
CORRECT ANSWER: 1.) Dependence on solar energy
2.) Biodiversity
, 3.) Chemical Cycling
QUESTION: Dependence on solar energy -
CORRECT ANSWER: (First principle of sustainability) The sun's input
of solar energy warms the planet and provides energy that plants use to
produce nutrients. The sun also powers indirect forms of solar energy
such as wind and flowing water, which we use to produce electricity.
QUESTION: Biodiversity (Principle of sustainability) -
CORRECT ANSWER: (Second principle of sustainability) The variety
of genes, organisms, species, and ecosystems in which organisms exist
and interact. The interactions among species, especially the feeding
relationships, provide vital ecosystem services and keep any population
from growing too large. Biodiversity also provides countless ways for life
to adapt to changing environmental conditions, even catastrophic
changes that wipe out large numbers of species.
