三、阅读理解
An ecosystem is like a giant web where all living things are connected. It includes not just plants and animals, but also the air, water, soil, and even the climate they live in. Take a pond ecosystem for example. The water provides a home for fish and frogs. Plants like water lilies grow in the pond, providing food and shelter. Insects buzz around the water's surface, while birds come to catch the insects. Even the tiny bacteria in the mud play an important role by breaking down dead plants and animals.
Forest example
In a forest ecosystem:
* Trees produce oxygen (O₂) through photosynthesis (光合作用).
* Deer eat grass and leaves.
* Wolves hunt deer to control their population.
* When wolves die, their bodies decompose and become nutrients for plants.
This balance keeps the forest healthy. But if humans cut down too many trees, deer may lose food, wolves will starve, and the whole ecosystem can collapse (崩溃).
