"Change the Ecological Bottle" Biology and Environment PPT Courseware

plants in eco bottles

Plants grow well.

The color is emerald green.

What role do plants play in eco-bottles?

Provide oxygen and food to animals.

What role do animals play in the ecobottle?

Provides nutrients and carbon dioxide to plants.

Reduce the water in the ecological bottle

Due to the reduction in water volume, the living space for animals and plants is reduced, and the amount of oxygen is reduced. Small fish with less water surface more often.

Increase the number of creatures in the ecological bottle

What will happen if you choose one of the ecological bottles and double the amount of water plants?

As aquatic plants increase, the amount of oxygen produced increases, and the number of fish surfacing will decrease;

What will happen if you choose another small fish with twice the size of the ecological bottle?

As the number of small fish increases, their oxygen consumption increases, and the number of times the small fish float to the surface will increase.

Add double the number of small goldfish to the ecological bottle you designed.

Observe and record the changes of the little goldfish in the ecological bottle:

The number of times the little goldfish floats to the surface increases

Observe and record the changes of plants in the ecological bottle:

The number of plants decreased

Observe and record the changes in the water in the ecological bottle:

The water has become turbid
