Question

In general, chemicals enter ecosystems through which two spheres? A. Atmosphere and hydrosphere B. Biosphere and lithosphere D. Biosphere and hydrosphere

Answer 1

The answer is option B.

Step-by-step explanation:

the biosphere and the lithosphere . The biosphere speaks to that locale of the earth involved by living creatures. People are essentially in charge of the abundance arrival of synthetic concoctions in the biosphere. Other life forms likewise discharge synthetic concoctions, procedures, for example, breath and photosynthesis. The lithosphere discharges synthetic concoctions through procedures, for example, weathering and volcanic action.

Answer 2

The appropriate answer is b. the biosphere and the lithosphere . The biosphere represents that region of the earth occupied by living organisms. Humans are mainly responsible for the excess release of chemicals in the biosphere. Other life processes also release chemicals, processes such as respiration and photosynthesis. The lithosphere releases chemicals through processes such as weathering and volcanic activity.
