Passage one
To deal with the lack of light so far beneath the surface of the ocean, many deep-a creatures employ a form of bioluminescence, a chemical reaction in their bodies that produces light but not heat. Biologists believe bioluminescence rves veral functions. First, for some fish, it acts like a flashlight by enabling them to e as they swim while in others, it helps them attract mates. And some creatures u their light to draw in other a life, which is then attacked and consumed. However, bioluminescence is a poor substitute for sunlight, so many deep-a creatures have developed extra nsors to assist them. For example, some have evolved stronger ns of smell to detect the chemical scents nt out by members of the same species, which enable them to find mates.
While going down deeper, the water places inten pressures on everything. To avoid being
crushed, many creatures have evolved by becoming smaller as oppod to the more inflexible body structures of animals living near the surface. And some creatures have specialized molecular structures that help them better withstand the pressure. The molecules they are made up of, are common in all fish and are responsible for the distinct smell most fish have, but fish living at great depths have more of them and therefore have an even more inten smell.
The temperature of the water here stays between -1℃ and 4℃, which is cold enough to freeze most life. Some animals move at slow speeds to conrve energy. Some spots on the ocean floor relea energy from the Earth’s interior. Around the hot spots, many life forms reside, and they have established their own unique ecosystems.
Another problem is food. There is a distinct lack of a life for predators to catch so that many others depend on marine snow, the remains of dead fish falling from levels above the deepest parts of the ocean. Deep-a creatures frequently have slower metabolisms that enable them to survive for long periods of time on small amounts of food. Since man

energy. Some spots on the ocean floor relea energy from the Earth’s interior. Around the hot spots, many life forms reside, and they have established their own unique ecosystems.(这里的水温保持在-1℃到4℃之间，这一温度足以冻结大多数生命。有些动物以慢速移动以保存能量。海底的一些地方从地球内部释放能量。在这些热点周围居住着许多生命形式，它们已经建立了自己独特的生态系统)”可推知，作者在第三段提到了地球的内部是为了解释特殊生态系统。故选D。
