Question

use the picture provided to help explain which three pairs of organisms are able to produce an offspring then explain which pair of organisms are the same species. what is the one thing that members of the same species can do that other periods of organisms cannot? then zing the figures above in your responses to the previous question develop a general definition of the word species in a complete sentence.

Answer 1

Question: which three pairs of organisms are able to produce offspring?

In order for two organisms to reproduce, they must overcome certain barriers. Some examples are ethological (behavioral), biological and geographical barriers.

Ethological: An example of ethological barriers can be seen in birds. To mate, male birds mostly perform dances to attract females of the same species. However, the dances of one species are not attractive to another species, which prevents mating.

Biological: An example of a biological barrier is the existence of different species. 2 different species cannot mate for different reasons (the sperm cannot unite with the egg or the reproductive apparatus cannot mate).

Geographical: An example of a geographic barrier is the place where they live. Although 2 birds can mate biologically if one is in Asia and the other in America, they will never meet and never mate.

In the 3 images below we see 3 pairs of organisms that cannot mate due to a geographical, biological and ethological barrier respectively. Therefore, the tree pair of organisms that are able to produce offspring are the tree upper pairs
