BIO 373 - Exam 3
change in the species composition of communities over time - correct answer ✔✔succession
an abiotic event that physically injures or kills some individuals and create opportunities for other
individuals - correct answer ✔✔disturbance
involves the colonization of habitats that are devoid of life, either as a result of catastrophic disturbance
or because they are newly created habitats - correct answer ✔✔primary succession
involves the reestablishment of a community in which most, but not all, of the organisms or organic
constituents have been destroyed - correct answer ✔✔secondary succession
Early species modify the environment in ways that benefit later species. The sequence of species
facilitations leads to a climax community. - correct answer ✔✔facilitation model
also assumes the earliest species modify the environment, but in neutral ways that neither benefit nor
inhibit later species. - correct answer ✔✔tolerance model
assumes early species modify conditions in negative ways that hinder later successional species. - correct
answer ✔✔inhibition model
limited to species belonging to same taxon - correct answer ✔✔taxonomic affinity
a group of species that use the same resources even though they might be taxonomically distant -
correct answer ✔✔guild
a subset of a community that includes species that function in similar ways but do not necessarily use
the same resources - correct answer ✔✔functional group
