Why
is
the
continuous-time
model
more
appropriate
for
modeling
lionfish?
Lionfish
reproduce
(and
die)
all
throughout
the
year,
so
their
population
size
is
(
continuous-time
model
is
more
appropriate
for
capturing
these
frequent
chang:
Compare
the
three
curves
shown
in
the
graph
at
the
end
of
the
section.
a.
How
does
the
curve
for
the
continuous-time
model
compare
to
the
curve
for
The
curve
for the
continuous-time
model
increases
less
steeply
than
the
cun
model,
but
both
level
off
at
the
same
carrying
capacity
by
2014.
(You
may
w
students
why
the
models
differ.
Note
that
in
the
continuous-time
model,
th¢
updates
constantly.
In
this
particular
discrete-time
model,
the
population
gi
once
a
year.)
b.
How
do
the
curves
for
both
models
compare
to
the
population
estimates
bas
might
explain
the
differences?
The
curves
based
on
the
models
are
much smoother
than
the
data-based
es
estimates
have
much
greater
year-to-year
variation,
including
a
big
spike
ir
around
the
carrying
capacity.
