An ecosystem bottle, also known as a "closed ecological system," involves placing a small amount of plants, animals that feed on these plants, and other non-living substances into a sealed transparent bottle, creating an artificially simulated miniature ecosystem.

In scientific teaching activities, the ecosystem bottle is a fascinating, dynamic, and highly useful tool.

Because most children enjoy raising and observing fish and various aquatic organisms in the ecosystem bottle, this nurturing and observation can enhance knowledge, promote exploration, deepen understanding, and bring aesthetic enjoyment.

The ecosystem bottle is a closed container that simulates a natural environment, allowing you to observe the operation of the ecosystem and the interactions between organisms. The following details how to create an ecosystem bottle to help you simulate a miniature ecosystem.

Firstly, you need to consider the type of ecosystem you want to simulate, such as a tropical rainforest, desert, grassland, etc. Then, based on the chosen ecosystem type, select suitable plants and animals. Also, consider the size and shape of the ecosystem bottle to provide sufficient space for the ecosystem. For the stability of the ecosystem, the resistance stability should be good, meaning the nutrient structure can be slightly more complex.

Materials needed for making an ecosystem bottle include:

1. Glass or plastic bottle: Choose a transparent bottle that allows observation of the interior. The size should be suitable for the desired scale of the ecosystem.

2. Soil: Select soil suitable for the designed ecosystem type. For example, a tropical rainforest requires moist, organic-rich soil, while a desert needs dry, granular soil.

3. Plants: Choose plants suitable for the designed ecosystem type. Similarly, a tropical rainforest may require tall trees and vines, while a desert may need drought-resistant plants.

4. Animals: Select animals suitable for the designed ecosystem type.

For instance, a tropical rainforest may need butterflies, birds, and insects, while a desert may require lizards, snakes, and insects.

5. Water: Provide enough water to sustain the life in the ecosystem bottle. You can choose to add a fountain or a drip system to simulate natural precipitation.

6. Air: Although the ecosystem bottle is sealed, ensure sufficient air circulation. You can create a small hole in the bottle cap to provide air.

7. Light source: Provide appropriate light to support plant photosynthesis. You can use LED lights or daylight lamps.

8. Temperature control device: You may need a temperature control device to maintain stability inside the ecosystem bottle. This could be a heating pad or a cooler, depending on the simulated ecosystem type and local climate.

9. Lid: Use a suitable lid to seal the ecosystem bottle, preventing water evaporation and the escape of organisms.

To keep the ecosystem bottle functioning normally and ensure the survival of organisms, regular maintenance is necessary. The key points for maintenance include:

1. Regularly check the bottle to ensure no organisms have died or require more food and water.

2. Periodically replace the water source to ensure cleanliness and freshness. Also, check if the water supply is sufficient and needs replenishing.

3. Regularly clean the interior and exterior of the bottle to maintain hygiene and aesthetics. Use a soft cloth and mild detergent for cleaning.

4. Avoid moving the bottle to prevent disturbance to the organisms. If you must move it, handle it with care and try not to disturb the inhabitants.

5. Take immediate action if any issues are detected, such as the death of plants or animals or deterioration of water quality, to prevent affecting the entire ecosystem.

Nature is an indispensable part of our lives, weaving the foundation of our existence with its vibrant colors and harmonious melodies. In this vast and mysterious universe, nature is our common refuge. Therefore, let us cherish every green leaf, and every flower, breathe in the fresh air, and feel the pulse of the earth. In the encounter with nature, we find tranquility, we find inspiration, awakening a profound reverence for life within our hearts.

May we always coexist harmoniously with nature, protecting this beautiful and precious shared home.
