1. Based on Graphicsa) Where is the position of the marine biota zone, make a zone inhabited by stenohaline and euryhaline groups. Explain!b) Why is the number of estuary water species the least compared to the other two biota groups?
2. Where is the productivity of plankton in the neritic and oceanic layers high? what is the reason for this?
Use the following passage to answer the next 5 questions.
You are studying the intertidal zone of a previously unstudied island. You find three species of barnacles on the rocks. Species A is most abundant in the upper intertidal
zone, Species B in the middle, and Species C in the lower, as shown below.
Species A dominates
Upper intertidal zone
Species B dominates
Middle intertidal zone
Species C dominates
Lower intertidal zone
Q6. You conduct an exclusion experiment: You locate three experimental areas on rock faces that are the same size and span all three intertidal zones (upper,
middle, and lower). In each experimental area, you exclude all but one species of barnacle for the duration of the experiment, as illustrated in the diagram
below.
The diagram also shows the numbers of individuals for the unexcluded species in each intertidal zone at the end of your experiment. Based on the data, what
