根据生态系统的理论:太阳能是所有生命活动的能量来源,它通过绿色植物的光合作用进入生态系统,然后从绿色植物转移到各级消费者,组成一条“光合食物链”。如:太阳能→草→兔→鹰。也就是说,没有阳光,就不能进行光合作用,生物也就不能生存。但地球上却有一个特殊的生态系统,一条特殊的食物链,它不需要阳光,生物照样能够生存。 According to the theory of the ecosystem: Solar energy is the energy source of all life activities. It enters the ecosystem through the photosynthesis of green plants and then moves from green plants to consumers at all levels to form a “photosynthetic food chain”. Such as: Solar → Grass → Rabbit → Eagle. In other words, without sunlight, photosynthesis cannot be carried out, and biology cannot survive. But there is a special ecosystem on the earth, a special food chain that does not require sunlight, and biology can survive.
