Section BRead this paragraph and answer the questions. Bees are an absolutely essential feature of global ecosystems, pollinating about 75% of the world’s food crops, including many fruits, vegetables, and nuts. What they do is essential for both food production and biodiversity. In recent years, bee populations have been declining rapidly due to such threats as pesticide use, habitat loss, climate change, and disease. Research indicates that in some regions, bee numbers have dropped by over 40% in the last 15 years. If bee populations continue to decline, the consequences could be catastrophic, not only for global food security but for most natural ecosystems. Without bees, it is not possible to maintain a healthy, balanced environment. Fill in the gap with ONE WORD from the paragraph. 3. Bees play an Answer Question 3[input] environmental role throughout the world.
