What is the narrow layer at the surface of the Earth where life can exist?

What is the narrow layer at the surface of the Earth where life can exist?

This generation of life in the thin outer layer of the geosphere established what is called the biosphere, the “zone of life,” an energy-diverting skin that uses the matter of Earth to make living substance.

What factors confine life to the biosphere?

A moderate temperature and an energy source are two physical factors that constrain living things to the biosphere.

Why Is the Biosphere located near the earth’s surface?

The biosphere is located near the Earth’s surface because most of the sunlight is available near the surface. Plants on land and in the oceans need sunlight to produce their food, and almost every other organism gets its food from plants and algae.

What are five factors that affect biospheres?

These too hot or too cold conditions may not have supported the life. Other smaller factors like climate, humidity, precipitation, temperature, erosion etc. change the land and living conditions around the living organisms. These factors have the capacity to effect at molecular levels.

What human activities affect biosphere?

The burning of fossil fuels and the growth of animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. In turn, this drives climate change.

What are 3 human activities that affect the biosphere?

A number of human activities influence the biosphere. Some examples are hunting, deforestation, pollution, and agriculture.

What happens if there are no decomposers on the earth?

Bacteria in the soil are also decomposers. Imagine what would happen if there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.

Is an earthworm a decomposer?

Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.
