Water pollution can clog the gills of fish, choking them. in this example, the is dependent on the .

The right answer are the biosphere is dependent on the hydrosphere.

1. About Biosphere

The idea of the biosphere, all living things that populate our planet, goes back to Lamarck. Then, in 1875, the Austrian geologist Suess compared the term biosphere with those of hydrosphere, atmosphere and lithosphere.

Therefore, the biosphere is the set of living organisms and their living environments, therefore all the ecosystems present in the lithosphere, the hydrosphere and the atmosphere.

2. About Hydrosphere

The hydrosphere refers to areas of the Earth planet occupied by water (or ice). This definition therefore includes: rivers, glaciers, oceans, seas, lakes, polar ice caps and groundwater. For some, it is necessary to supplement these environments by the atmosphere (especially the troposphere), where large quantities of water vapor are in suspension.

*** Contamination of the hydrosphere is the change in the composition and characteristics of water caused by various pollutants, most frequently those of human activity.

Deep and surface waters may be contaminated by atmospheric precipitation (acid rain, soil erosion in the watershed). Some aquatic organisms have the ability to eliminate a portion of pollutants. These, however, are not enough to eliminate the large amount of pollutants caused by human activities. All these wastes contaminate water and alter its quality and unbalance aquatic ecosystems.

This waste can be divided into three major groups:

-The biological pollutants

-The chemical pollutants

-The physical pollutants

Pollution in its broad sense concerns both molecules that are not naturally present in the environment (exogenous), that those that are (endogenous). However, in the latter case, it is the place and concentration to which they are found that are not natural.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
