Question

Select one: a. The two species of barnacles do not compete with each other because they feed at different times of day. b. Balanus is a predator on Chthamalus. c. Balanus is inferior to Chthamalus in competing for space on rocks lower in the intertidal zone. d. Balanus and Chthamalus have a +/+ relationship. e. The removal of Balanus shows that the realized niche of Chthamalus is smaller than its fundamental niche.

Answer 1

E. Balanus removal shows the realized niche.

Step-by-step explanation:

• The first option is not valid because not the barnacles but the warblers feed at different time and this is called resource partitioning.
• The second option is not correct because balanus and chathamalus both are species of barnacles and feed on the same resources.
• The third option is not correct as it is not inferior but it is superior to chathamalus.
• and the fourth option is not valid because it has a-/- relationship
• so, the last option is correct as the balanus removal shows realized niche of chthamalus.
