Question 17:

a.        The phenology problem shows us that climate change affects all living things in nature. When we protect the environment, we help keep the natural timing stable and protect ecosystems.

b.        Since birds migrate later, they miss the peak time when insects appear. If animals cannot find enough food, they become weak and may die.

c.        Although flowers bloom earlier now, some animals do not arrive in time to find food. When the timing is wrong, the food chain breaks and animals suffer greatly.

d.        Because the Earth gets warmer, the seasons change earlier than before. If spring arrives one month early, animals wake up from sleep at the wrong time.

e.        Phenology means the natural timing of plants and animals, and it is very important for nature. When flowers bloom at the right time, bees can collect pollen and pollinate them.
