Marsupials, such as kangaroos, koalas, and wombats, are mammals that care for their newborn young in a pouch. all marsupials that are found in australia are thought to have evolved from a single species that migrated to the island and then adapted to the various niches. what does this example illustrate?

The correct answer is adaptive radiation.

Explanation:

Adaptive radiation is a process of rapid diversification of an ancestral species into a large number of descendant species in a different environment with adaptive morphological and physiological traits.  

Over 200 species of Marsupials mice, moles, flying squirrels and flying phalanger are found in Australia continent which was formed as a result of adaptive radiation from ancestral species to occupy the different niches of Australia.

Thus, adaptive radiation is the correct answer.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
