Question

a company sells a sealed glass globe called an "ecosphere" (true story). in the globe, there is water and aquatic plants and animals. Air cannot get into or out the globe because it is entirely sealed. Yet, the animals and plants can survive indefinitely within the globe. a. Explain how it is possible that animals and plants can survive in a sealed environment together.

Answer 1

Answer:It is possible that animals and plants can survive in a sealed environment together because there is food and water inside the globe for the animals and plants.

Answer 2

The conservation of mass and energy comes into play.

Energy is not a problem since sunlight can go through glass. The plants will grow and reproduce, producing oxygen that enters the water. Animals eat plants and get energy from them. They too grow and reproduce. They also release carbon dioxide into the water, which plants use to make food.

This cycle can continue forever, or at least for a long time.
