B. Their remote location has kept out invaders.
ANSWER IS:
A. Artificial translocation of organisms
B. Physical removal of organisms
D. Habitation modification
EXPLANATION:
Natural distributions of biomes are often severely modified by human activities through physical removal, habitat modification and artificial translocation of organisms.
Humans can alter natural distribution patterns astonishingly quickly
Artificial translocation of organisms :
It leads to introduction of exotic species that have an effect on crops and pets
Physical removal of organisms :
Physically organisms are removed by modification of landscape for civilization. It effects overall distribution patterns.
Habitat modification :
Habitat is the natural environment where an organism lives. Human activities are responsible for the alterations in the habitat of many organisms that leads to their extinction.
For example, because of tropical rain forest removal it leads to loss of 27 million acres of rain forest per year.
Ecosystem can also effects from rain forest removal. Biodiversity lost through extinction.
The theory
of a land bridge between South America and Africa as an explanation for similar
fossils on the two continents is not supported today because there are
no remnants of the bridge in the Atlantic Ocean.
<span>A </span>land
bridge, in biogeography<span>, is an </span>isthmus<span> or wider land connection between otherwise separate areas, over which
</span>animals<span> <span>and </span></span>plants<span> <span>are able to cross and </span></span>colonize<span> <span>new lands. A land bridge can be created by </span></span>marine regression<span>, in which </span>sea
levels<span> <span>fall, exposing shallow, previously submerged sections of </span></span>continental shelf<span>; or when new land is created by </span>plate tectonics<span>; or occasionally when the sea floor rises due to </span>post-glacial rebound<span> <span>after an </span></span>ice
age.
