A closed ecological system is an ecosystem that sustains life by fully reusing all of the resources at hand, in particular through cycles wherein exhaled carbon dioxide, fuel, and other waste materials are transformed chemically or through photosynthesis into oxygen, water, and food.
Why ecosystem is considered an open system?An open system allows for the flow of both matter and energy with its surroundings. An open system can be found in any environment. Sunlight, for instance, can provide energy to the system and heat can be released.
It continues to be the biggest artificial closed ecosystem ever made. Biosphere 2, which was built between 1987 and 1991, was initially intended to show that closed biological systems could sustain and preserve human life in space in place of the biosphere on Earth.

Using relative dating techniques, give a relative age for the fault in Figure 13-1?
Fault occured sometime between units ________ & ________.
Answer:Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.
Explanation:Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing. As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.
How is the fossil record used to date artifacts?
Through the use of radiocarbon dating, the fossil record can used to date artifacts.
What is a radiocarbon dating?This is a technique that allows people to learn about the ages of biological specimens such as animal, wood, artifact etc
