In which layer of the Earth are living organisms can be found?

In which layer of the Earth are living organisms can be found?

biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.

In which layer do we find living organisms What is the reason for their existence there?

The very lowest layer, which contains 90% of the atmosphere’s mass, is called the troposphere. This is also where all living things are found and where all weather occurs. Airplanes fly at the very top of the troposphere, so they can fly over the weather, which causes turbulence.

Which layer of Earth contains plant and animal life?

The biosphere is that part of the Earth where living things thrive and live. It is the portion of the planet that can sustain life. The Earth has three other spheres: the atmosphere, the lithosphere, and the hydrosphere.

What is Earth’s stratosphere?

The stratosphere is a layer of Earth’s atmosphere. It is the second layer of the atmosphere as you go upward. The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. The top of the stratosphere occurs at an altitude of 50 km (31 miles).

What layer of the Earth’s atmosphere is the layer next to the Earth?

troposphere
The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface.

What makes life possible in the biosphere?

Over a long period of time, the atmosphere developed a mix of oxygen and other gases that could sustain new forms of life. The addition of oxygen to the biosphere allowed more complex life-forms to evolve. Millions of different plants and other photosynthetic species developed.

What is the basis for all living things every living thing contains this element?

Carbon. Carbon forms the basis for all life on Earth; indeed, life forms on Earth are referred to as carbon-based life forms, emphasizing the importance of this element for life. Carbon atoms readily bond to other atomic elements, such as oxygen and nitrogen.

Is fire a living thing?

People sometimes think fire is living because it consumes and uses energy, requires oxygen, and moves through the environment. Fire is actually non-living. The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells.

Is Earth a living organism?

No, planet Earth is not a living entity like a human being, a badger, a mosquito, or even a tomato plant. For example, Lovelock and Margulis noted that Earth appears to display a form of self-regulation, otherwise known as homeostasis.

How are the troposphere stratosphere and thermosphere important?

The troposphere contains 75% of the atmospheric mass as well as the oxygen and carbon dioxide plants and animals need to survive. The stratosphere’s ozone layer absorbs ultraviolet radiation which is harmful to living organisms. The thermosphere absorbs solar radiation and helps to regulate the Earth’s temperature.

Which is the second layer of the atmosphere?

ozone layer. Encyclopedic entry. The ozone layer is one layer of the stratosphere, the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. The ozone layer is one layer of the stratosphere, the second layer of the Earth’s atmosphere.

Which is the most dense layer of the atmosphere?

Earth’s Atmospheric Layers. Diagram of the layers within Earth’s atmosphere. The troposphere starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region.

Which is the habitat for all living things on Earth?

Both the geosphere and hydrosphere provide the habitat for the biosphere, a global ecosystem that encompasses all the living things on Earth. The biosphere refers to the relatively small part of Earth’s environment in which living things can survive.

Where does the thermosphere start and end on the Earth?

The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.
