It is because pesticides contain dangerous substance that can harm living things. Example of negative effects is 'Eutrophication'. This process is the when pesticides are used and promotes the growth of algae in a water source and it makes underwater plants cannot do their photosynthesis. Fishes will die due to lack of oxygen and lot of unabsorbed carbon dioxide that are dissolved in water.
Xenon is not dangerous to humans or other living things.
Biochemist
The proteins known as enzymes are vital to living things because they speed up chemical reactions up to a trillion times.
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
Mineral
Pesticides are sometimes called "BIOCIDES" because of their effects on living things.
raw sewage, chemical pesticides and fertilizers
In the 1700s, scientists discovered the chemical and physical basis of living things, and soon they realized that the chemical organization of all living things is remarkably similar. Microorganisms, as forms of living things, conform to this principle and have a chemical basis that underlies their metabolism.
All around us, living things or inorganic things are chemical compounds.
All living things use chemical energy.
There are probably a number, but generically, they are those pesticides made in a factory out of simple ingredients (eg DDT - dichlorodiphenyltrichloroethane) rather than those that are extracted from living things (eg Pyrethrum)
Ionizing radiation can be dangerous to living things, as it upsets the chemistry in living cells by breaking covalent bonds between atoms. Even if the radiation is not ionizing, such as in neutron flux, damage can be done there as well, due to activation processes that change the chemical identity of atoms.
Yes. It kills living things.
Being strongly radioactive, americium is dangerous.
Xenon is not dangerous to humans or other living things.
