Answer: B. Two hawks share a hunting territory
Explanation: There are two main types of species competition. There is intraspecific competition and interspecific competition. Let's define both of these terms to better understand their differences and how to answer these questions.
Intraspecific competition refers to competition between individuals in the same species over resources. An example of this is male elks headbutting each other in order to win reproductive rights with females. Another example of this is pigeons competing over bread that's been tossed upon the ground.
Interspecific competition refers to competition between different species over the same resources. An example of this is elephants, lions, and hippos competing over the same watering hole in the savannah, or birds and squirrels competing over living spaces within trees.
Thus, only choice b is an example of intraspecific competition since this scenario involves two members of the same species (in this case hawks) competing over hunting territory. Choices a, c, and d all mention competition between multiple species. These choices would be examples of interspecific competition instead.
