Question

Mammals have lungs that have millions of alveoli that increase the surface available
for gas exchange
Two species utilizing the same food source is an example of interference
competition
Parasitism provides nutrients for the host
The study of how organisms interact with one another and with their nonliving
environment is ecology
A population grows exponentially when the birth rate exceeds the death rate and
immigration exceeds emigration
During respiratory exchange, carbon dioxide moves from the blood into the alveoli
due to diffusion down a concentration gradient
Density-independent factors are typically abiotic.
_Small body size is a typical feature of K-selected organisms
An insect population grows exponentially until an early winter freeze kills almost
all of the insects. The next spring, the population grows exponentially again. This type of
population growth is called sustained cycling.
Generally, r-selected organisms exhibit long life spans and extended parental care
of offspring
A population of rabbits introduced into an island grew rapidly for a few years and
then the growth slowed down and stabilized. The population become stable because the
carrying capacity was reached.
