Q1. You wish to collect organisms from the lowest part of the intertidal zone in your study area. To avoid having to swim or dive to collect them, you should time your work to coincide with: A spring high tide. A spring low tide. A neap high tide. A neap low tide. Q2. The organisms in your study area that will be maximally exposed to air over the course of a lunar month live: Between neap low tide height and neap high tide height O Between neap low tide height and spring high tide height Between neap low tide height and spring low tide height. Between neap high tide height and spring high tide height. Q3. When Semibalanus is excluded from below the tidal zone: o Many Chthalmalus individuals grow we n the Semibalanus exclusion area Chthamalus individuals grow in the Semibalanus exclusion area but they tend to die quickly through too Occasional much exposure to water. n the exclusion area because they cannot reach and settle there Chthamalus individuals do not grow at a O Any of the above are possible on different rocks (e.g., in different runs of the simulation)

Explanation / Answer

Q.1) b- a spring low tide

Q.2)d- between neep high tide height and spring high tide height

Q.3)a- many semibalanus individual grow well in the chthamalus exclusion area

Q.4) b-occasional semibalanus individuals grow in the chthamalus exclusion area but tend to die quickly through too much exposure to water.
