Answer:
The options
a. sympatric speciation; vicariance
b. allopatric speciation; vicariance
c. sympatric speciation; dispersal
d. allopatric speciation; dispersal
The CORRECT ANSWER IS d.
d. allopatric speciation; dispersal
Explanation:
Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).
Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.
In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
Answer:
organism that will die off
Explanation:
because
Answer:
b. As invasive species increase, it causes biodiversity to decrease
Explanation:
Invasive species refers to those species of organisms that are foreign (non-native) to a particular environment or habitat with the tendency to outgrow and outcompete the native species in that habitat. Due to their fast reproductive and growth rate, they tend to diminish the population of native species by using up the available nutrients.
Biodiversity is the richness of organism species on Earth. When invasive species increase in a particular habitat or ecosystem, they cause the biodiversity in that habitat to decrease because they tend to take charge and dominate, causing harm to every other species. Hence, As INVASIVE SPECIES INCREASE, it causes BIODIVERSITY TO DECREASE
