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.

2010 with the width in 2015.
Width of hooch (m)
According to the graph, the difference between the width of the beach in the years 2010 and 2015 is that in 2015 the variation was 16m while in 2010 it was 5m.
What is seen in the graph?The graph shows the variation in the width of the beach according to its distance in the years 2010 and 2015.
In the year 2010 the width of the beach has very little variation because it goes from 20m at the distance 0 to 25m at the distance 1000m, so its variation is barely 5 meters.
On the other hand, in 2015 the width of the beach varies to a greater extent because at distance 0 it is 15m wide and at distance 1000 it is 31m wide.
According to the above, the width of the beach has greater variation in 2015 because it has 16 meters of variation, while in 2010 it has only 5 meters of variation.

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.
