مثال 1
Ecologist Ana Ruiz noticed that some meadows near her research station had far more wildflowers than others, even though the soil and rainfall were similar. After several years of observation, she found that the flower-rich meadows were the ones where grazing animals such as deer visited regularly. The animals ate tall grasses that would otherwise shade the ground, allowing shorter flowering plants to receive enough sunlight to grow.
