What is the main content of the biology class in the fish tank?

The biology class in the fish tank focuses on aquatic life, including fish, invertebrates, microorganisms, etc. The course covers the ecosystem, life cycle, behavioral habits, adaptability and other aspects of these organisms, as well as their relationship with the environment and their impact on humans.

Specifically, the biology class in the fish tank will study different species of fish in detail, including their characteristics, habits, and how to care for them. The course will also introduce the requirements of the fish breeding environment, such as water temperature, water quality, feed, etc. In addition, invertebrates and microorganisms will also be introduced, including their species, characteristics and habits.

At the same time, aquatic plants are also an important part of biology classes. Aquatic plants not only beautify the fish tank, but also provide oxygen and shelter to the fish. The course will introduce the different species of aquatic weeds, their growth habits, conservation methods, and their relationship with fish.

The light, water quality and nutrient requirements of aquatic plants, as well as how to prune and propagate aquatic plants, are also important aspects of the course.

To sum up, the biology lesson in the fish tank focuses on the role of aquatic organisms in the fish tank ecosystem and how to maintain the balance of this ecosystem.

Hello, the unexpected thing about the biology class in the fish tank is that the main internal judge Xiangrong said: about to take the biology Li Ze class, the biology teacher brought a big fish tank, he accidentally knocked over the fish tank, and the classroom became an underwater world. But the teacher was not in a hurry, he carefully explained the knowledge of fish to everyone.

After class, everyone cleaned up and was still unsatisfied. <>

In fact, after knowing this kind of story, the biggest feeling is that the biological cycle is everywhere. No matter how big or small, how much or too little is the space, in fact, every part is in the chain of simple and good things. Even a small fish tank is a complete ecosystem.
