20.2 True/False Questions
1) The Earth's biodiversity is evenly spread across the planet.
2) A biome is a large, stable community of plants and animals whose boundaries are closely
linked to climate.
3) Biogeographic regions (realms) are delineated based on species assemblages and their
evolutionary history.
4) Alfred Russel Wallace's zoogeographic realms roughly correspond to continental plate
boundaries.
5) The boundaries of biogeographic regions are usually quite arbitrary, usually following
political boundaries rather than being based on biophysical criteria.
6) New Zealand and Australia have remarkably similar fauna indicating the two were likely once
directly connected as a single land mass or via a land bridge during critical evolutionary times.
7) "Wallace's line," which serves as a dividing line between different biogeographic realms and
separates several present-day Indonesian islands from one another, is so named to show the
arbitrary nature of such delineations.
8) The biome concept has been applied equally to marine and aquatic systems as it has to
terrestrial systems.
9) Biomes are defined based on idealized potential mature vegetation in a given area rather than
the actual vegetation.
10) The boundaries between biomes are usually abrupt and related to rapid environmental
changes, such as in climate or topography.
11) The range of environmental conditions frequently found in ecotones make them areas of high
biodiversity.
12) Most non-native species introduced to a new community become established.
13) Invasive species can alter community dynamics and may lead to declines in native species.
14) Though occupying only 7% of the world's total land area, tropical rain forest's account for
approximately 50% of the Earth's species and about half of its remaining forests.
15) Due to the dense tropical rain forest canopy, only about 1% of the sunlight arriving at the
canopy reaches the forest floor.
16) In part, the high diversity of the tropical rain forest is due to the extremely fertile soils found
in the biome.
17) Each year, an area of tropical rain forest approximately the size of Wisconsin is cleared.
18) Despite widespread tropical deforestation, tropical rain forests are able to quickly regenerate
owing to the extremely fertile conditions in the biome.
19) In general, the tropical seasonal forest and scrub biome has more erratic rainfall than the
tropical rain forest biome.
