What is the defining characteristic of a closed system, such as a biodome?

It completely prevents both energy and matter from entering or leaving.

It allows energy to enter but prevents the exchange of matter with the outside.

It relies on a constant external supply of water and nutrients to survive.

It primarily functions by exporting waste materials to the surrounding environment.

Why is the constant recycling of materials like water and carbon essential for the long-term survival of organisms in a biodome?

Because new matter cannot be introduced into the sealed environment.

To generate the light energy that is needed for photosynthesis.

To prevent the temperature inside the biodome from becoming too high.

Because the system needs to export these materials to avoid pollution.

A breach in the dome's seal occurs.

The sun's light is blocked for a day.

All the plants inside die suddenly.

The internal water cycle speeds up.

A sealed terrarium in sunlight.

An island that trades with the mainland.

Energy is recycled internally, while new matter flows in from the outside.

Energy flows through the system, while matter is cycled continuously within it.

Both energy and matter are continuously recycled within the sealed system.

Matter is converted into energy to power the system's life processes.
