If fruit trees, shrubs and insects decrease in a forest, what will be the effect on biodiversity? A Diversity may decrease due to loss of food and microhabitats B Every organism will get more food C Forest will become automatically safe D All organisms will become domestic
Correct answer: A Small resources also support many species. Exam tip: remember microhabitats and food base.

If herbivores decline greatly in a forest, grazing on vegetation may reduce but what will happen to carnivores? A Carnivores will be affected by food shortage B Carnivores will become plants C Carnivores do not need food D There is no ecological relation
Correct answer: A One change can have different effects at different levels. Exam tip: study food chains in a balanced way.

If bird nests are decreasing in an area, which investigation is most correct? A Survey breeding sites, tree availability, human disturbance and food sources B Record only the colours of birds' feathers C Measure only the total length of roads in the area D Count only the number of nests compared with the previous year
Correct answer: A A proper investigation must examine all major likely causes of nest decline. Suitable breeding sites and trees are needed for nesting, while human disturbance and reduced food availability can make birds leave an area or breed less successfully. Counting nests alone can confirm the decline, but it cannot identify its cause. Exam tip: For wildlife-decline questions, consider habitat, food, breeding conditions, and human activities together.
