9 exam-style questions with model answers, plus 12 quick multi-choice questions — every question on the site for this standard, grouped by the 3 pages of notes they come from.
Write a full answer before you reveal the model one — that comparison is where the marks come from. Every block links back to the notes that teach it.
Define zonation and succession, and give one example of each.
Explain why zonation occurs on a rocky shore, referring to a specific environmental factor.
A student finds no clear pattern in their transect data from a rocky shore. Discuss how they should report this, and what could explain the absence of a pattern.
Give two abiotic and two biotic factors that could affect the distribution of organisms in a community, and state when you would use a transect rather than quadrats.
Explain why quadrats must be placed randomly, and explain why a transect on a rocky shore must run perpendicular to the water line.
A student measures light intensity and records plant species along a transect from open ground into a forest. Discuss how they should use both sets of data together, and evaluate the limitations of concluding that light causes the pattern they find.
State what Merit requires beyond Achieved for this standard, and name three types of interrelationship you could use.
Explain how a species' adaptations set the upper limit of its band on a rocky shore, and explain why a different kind of factor usually sets the lower limit.
Use an environmental factor and the biology of interrelated species to explain fully why a rocky shore shows distinct bands rather than a gradual change in species composition.
