two factors that determine range are,
in constant flux as abiotic and biotic
factors change overtime Abiotic factors - temperature, rainfall, the presence
of geographical structures like mountains and oceans, and large scale ongoing
and historical process such as continental drift Biotic factors - past and
current presence of other species that provide habitat, food, or competition Ranges
are dynamic
Observe birds nesting in cut patches and uncut patches of forest.
-Hypothesize that more birds nest in cut forest patches.
-Develop a plan for conducting nest counts in several similar-sized patches of cut and uncut forest.
-Count the number of nest found and record the data.
-Compare the data collected concerning nests from cut and uncut patches of forest.
Determine whether more birds nest in cut or uncut forest patches and share this conclusion with other researchers.
