Symbiosis is when two different living things live closely together for a long time. In this relationship, at least one of them benefits. These relationships help living things survive in their environment.

One example is bees and flowers. Bees collect nectar from flowers for food, and while doing this, they spread pollen so flowers can grow seeds. Both benefit from the relationship. Another example is clownfish and sea anemones. The clownfish hides among the anemone’s tentacles to stay safe from predators. In return, the clownfish helps keep the anemone clean. A third example is ticks and animals like dogs. Ticks drink the animal’s blood to survive, but the animal is harmed. This is an example of parasitism.

If we think of Taiwan as an ecosystem, there are several factors that limit how much the human population can grow. One major factor is land. Taiwan is a small island, and much of it is mountainous, so there is limited space for housing and farming. This leads to crowded cities and high housing prices. Water is another limiting factor because Taiwan depends on rainfall, and droughts can reduce the water supply for people, farms, and factories. Food is also limited since there is not much flat land for agriculture, so Taiwan relies on imported food. Energy is another concern because most energy resources are imported. Natural disasters such as typhoons and earthquakes can damage infrastructure and affect daily life. Finally, social factors like low birth rates and an aging population also limit population growth.
