Question

According to Darwin, the organic evolution is due to
A.Intraspecific competition
B.Interspecific competition
C.Competition within closely related species
D.Reduced feeding efficiency in one species due to the presence of interfering species

Answer 1

Charles Robert Darwin was an english naturalist, geologist and biologist. He was known for his contribution in the field of evolution. He introduced that evolution resulted from a process of natural selection.

Complete answer:
Organic evolution:
a.The term organic evolution was proposed by Charles Darwin.
b.Organic evolution means that the present complex plants and animals have evolved from the earlier simpler forms of life by gradual changes.
c.According to the organic evolution simple multicellular like invertebrates have evolved from the unicellular organism.
d.And simple multicellular organisms evolved into the complex multicellular organisms like plants and animals.
e.According to Darwin, organic evolution is due to interspecific competition.
f.Interspecific competition is a type of competition in which the individuals of two different species compete for the same resources such as food, water, habitat, etc.
Therefore, it has been clear from the above discussion that according to Darwin, the organic evolution is due to interspecific competition.

Hence the correct answer is option(B)

Note: Evolution is the change in the characteristics of any species that occur over a long period of time over several generations.
