Explanation: Animal social behavior, the suite of interactions that occur between two or more individual animals, usually of the same species, when they form simple aggregations, cooperate in sexual or parental behavior, engage in disputes over territory and access to mates, or simply communicate across space.
Answer:
A) hybridization; morphospecies
Explanation:
The biological species concept is the concept which can define a species as an individual of a large population which can interbreed and produce an offspring in a population. The concept was given by Ernst Mayr.
Morphospecies refers to the species which can be characterised by the differences in their morphological features like in the Oak, willows and the dandelions.
The biological species concept is not valid or complicated in the case of the morphospecies like in the Oak, willows and the dandelions as the individuals of these three population can exchange their genes through the process of hybridization.
Thus, Option-A is the correct answer.
