Ethics is a term used in scientific experiment to refer to conducting experiments under the correct rules of conduct necessary when performing a research.It is a moral responsibility of a researcher to protect participants in a research from harm.Some of the ethical issues are: beneficence, respecting privacy, informed consent and respecting anonymity and confidentiality.
All scientific studies that involve human or animals become a matter of ethical concern and this is so because there are several moral principles of the society which are at stake.
For example - society believes than even an embryo in the womb of a woman, who has not taken birth has the right to live and thus studies such as "stem cell researches" involving usage of embryonic cell are ethically condemned.
Genetic studies are also a matter of ethical concerns as society believes that hereditary history is a personal matter and should not be tried and tested openly.
Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere. Humans (biosphere) use farm machinery (manufactured from geosphere materials) to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants.
