How does the conversion of
natural forest to human land
uses affect an ecosystem?
decomposers
In a marsh ecosystem, alligators,
woodstorks, muskrats, cattails,
ferns, and grasses make up a food
web. If a disease eliminates the fern
population, what would be a
consequence?
If lizards are eating insects and
one year, a disease affecting
lizards caused a widespread
decline in their population. What
is a consequence of this event?
Organisms that get energy and
nutrient requirements from eating
animal tissue
There will be a decrease
in biodiversity in the
ecosystem.
organisms that break
down dead or decaying
organisms, and in doing
so carry out the natural
process of decomposition.
The animals relying solely
on ferns for food would die
out.
an increase in the insect
population
Which of the following best
explains how the Red
Imported Fire Ant has
affected native ant species
in the U.S. that do have
predators?
What will most likely
happen to the population
of polar bears as a result
of global warming?
What determines the
carrying capacity of an
ecosystem?
The Red Imported Fire Ant
caused a decline in native
ant species by competing
for their resources.
It will decrease as the
habitat suitable for polar
bears decreases.
the most limited resources
required for survival
or
the needed resource that
begins to run out first
What changes in the
ecosystem will take place
during the course of
succession?
Which of the following is a
characteristic of pioneer
plant species in general?
The smaller pioneer
species will eventually be
shaded out by the growing
trees and will not be able to
grow.
Their seeds tend to need
full sunlight to sprout.
