Which statement about ecology is true?
a. All organisms living in the same area are strongly connected to one another.
b. All organisms interact with features in their environments.
c. Organisms can only be directly connected through their ties to shared
features of the environment.
d. Both b and c
All organisms interact with features in their environments.
Suppose that individuals of a particular genetic strain of Drosophila melanogaster
reproduce at an earlier age than do other strains of this species. As a consequence,
they tend to die sooner. Which maxim does this phenomenon exemplify?
a. Everything goes somewhere.
,b. No population can increase in size forever.
c. There is no such thing as a free lunch.
d. Space matters.
✓ There is no such thing as free lunch
What is one reason that amphibians are especially good biological indicators of
environmental conditions?
a. They live in both terrestrial and aquatic environments.
b. It is difficult for pollutants to pass through their skin.
c. They are declining in number.
d. They can tolerate high levels of pollution.
✓ They live in both terrestrial and aquatic environments
abiotic
✓ of or referring to the physical or nonliving environment
Adaptation
✓ A physiological, morphological or behavioral trait with an underlying genetic basis
that enhances the survival and reproduction of its bearers in their environment
,Biosphere
✓ The highest level of biological organization, consisting of all living organisms on
Earth plus the environments in which they live; located between the lithosphere and
the troposphere
Biotic
✓ Of or referring to the living components of an environment
climate change
✓ Directional, change in climate over a period of three decades or longer
Community
✓ A group of interacting species that occur together at the same place and time
consumer
✓ An organism that obtains its energy by eating other organisms or their remains
Controlled Experiment
✓ A standard scientific approach in which an experimental group (that has the factor
being tested) is compared with a control group ( that lacks the factor being tested)
, Ecology
✓ The scientific study of interactions between organisms and their environment
Ecosystems
✓ All the organisms in a given area as well as the physical environment in which they
live; can include one or more communities
An association of populations of different species living in the same area is called a(n)
a. population.
b. community.
c. ecosystem.
d. biosphere.
✓ community
In a grassland ecosystem, plants capture 180 units per day of solar energy, and they
use up 70 units per day in respiration. Animals consume about 20 units per day of the
plants. The NPP of this system is _______ units per day.
