Biosphere 2 was an attempt by scientists to build a completely closed ecosystem in Arizona. It failed because of the
1. inability of soil microorganisms to recycle nitrogen.
2. decreased level of oxygen through respiration by soil microorganisms.
3. disease outbreak caused by soil microorganisms.
4. increased level of carbon dioxide produced by photosynthetic microorganisms.
5. contamination of food by soil microorganisms.
Can someone help me answer these science questions?

I need help on this question. How would the removal of worms do that?
how would the removal of worms effect the biosphere, hydrosphere, lithosphere, and atmosphere in a small ecosystem such as a garden

B)A hypothesis is a standard unit of measurement.
C) A kg is a standard unit of measurement.
D) Controlled experiments have confirmed the meteorite-impact hypothesis

I need atleast 5 animals and 5 plants that is needed in a biosphere. And why. I need something that’ll balance the ecosystem.

Biosphere II was creates in 1991 to test the idea that scientists could bild a sealed, self-sustaining ecosystem. They discovered that oxygen levels were dropping. However, the corresponding carbon dioxide levels were not rising. They later found out that the carbon dioxide had reacted with water in the concrete. The concrete absorbed carbon dioxide up to 5 years.
QUESTION: Why did scientsts fail to predict that this would happen?

In 10 episodes here on youtube Dr. Harding lead you into a new understanding of our beloved mother Earth. Earth, or Gaia as he prefers to say, needs to be taken care of now. The human rase is about to amuse itself to death on how we exploit the resources. Inspired by James Lovelock (1919 – ) who is a pioneer and rolemodel in this field. He is an independent scientist, author, researcher, environmentalist, and futurist. He is known for proposing the Gaia hypothesis, in which he postulates that the Earth functions as a kind of superorganism. This qoute from the great philosopher says it all: “All life has intrinsic value, irrespective of its value to humans” – Arne Naess, (1912 – 2009) RIP Arne Næss was the founder of deep ecology. He is widely regarded as the foremost Norwegian philosopher of the 20th century Dr. Harding is bringing it all together!
