Ecology

Definition The ecology is the study of the interactions of living things with each other and physical environment.

Biosphere The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth, a closed (apart from solar and cosmic radiation) and self-regulating system. The biosphere is the global ecological system integrating all living beings and their relationships.

Biosphere The biosphere is postulated to have evolved, beginning through a process of biogenesis or biopoesis, at least some 3.5 billion years ago.

The Career related to Biosphere Biologist : The person who study humans, plants, animals, and the environments in which they live .

Atmosphere The atmosphere is a layer of gases that may surround a material body of sufficient mass. And that is held in place by the gravity of the body.

Atmosphere The atmosphere may be retained for a longer duration, if the gravity is high and the atmosphere's temperature is low.

The career related to Atmosphere Meteorologist : The scientist who study of the earth's atmosphere and the weather which occur in it.

Ecosphere The ecosphere is an imaginary shell of space surrounding stars where conditions are such that life might survive.

Ecosphere The ecosphere can refer to the Earth's spheres, a planetary ecosystem consisting of the atmosphere, the geosphere (lithosphere), the hydrosphere, and the biosphere.

The Career related to Ecosphere Ecologist : The scientific who study the relations that living organisms have with respect to each other and their natural environment.

Hydrosphere The hydrosphere is the liquid water component of the Earth. It includes the oceans, seas, lakes, ponds, rivers and streams. The hydrosphere covers about 70% of the surface of the Earth and is the home for many plants and animals.

Hydrosphere The Hydrosphere in physical geography describes the combined mass of water found on, under, and over the surface of a planet.

The Career related to Hydrosphere Hydrologist : The scientific study of the properties, distribution, and effects of water on the earth's surface, in the soil and underlying rocks, and in the atmosphere.

Lithosphere The lithosphere is the outer solid part of the earth, including the crust and uppermost mantle. The lithosphere is about 100 km thick.

Lithosphere On Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.

The Career related to Lithosphere Geologist : The scientist who study the solid and liquid matter that constitutes the Earth as well as the processes and history that has shaped it.

Conclusion We know the Biosphere , Atmosphere , Ecosphere , Hydrosphere , and Lithosphere are important part of Earth. So we need to save our Earth.
