This is one reason why it might hurt
biodiversity if you move an “invasive
species” into a habitat it doesn’t
currently occupy
What is “it could better adapt to
the niche or have no natural
predators…it could drive native
species out or to extinction”
Continue

depths of the ocean to miles into
the atmosphere where living
things are.
What is the biosphere
Continue
900
One of the factors that makes up

A measurement of the number of
individuals living in a defined space
What is population density

Individuals may live in this kind of
“dispersion pattern” if they are
territorial or compete for the same
resources often. (example is birds’
nesting habits)
What is uniform dispersion
Continue
300
In order to gain protection or help each
other out more readily in accessing
food and other resources, individuals
within a population may have this type
of dispersion.
What is “clumped dispersion”

This is how population density and
population dispersal are different
What is population density measures
