LIFE SCIENCE

Detailed explanation-1: -The biosphere is made up of the parts of Earth where life exists-all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.

Detailed explanation-2: -The biosphere (from Greek bíos “life” and sphaira “sphere"), also known as the ecosphere (from Greek oîkos “environment” and ), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth.

Detailed explanation-3: -Parts of the lithosphere, hydrosphere, and atmosphere make up the biosphere. The lithosphere is the outermost layer of the Earth’s crust; essentially land is part of the lithosphere. The hydrosphere is composed of all the areas that contain water, which can be found on, under, and over the surface of Earth.
