<span>a. Species P and Q are equally related to species T</span>
<span>Both photoautotrophs and chemoautotrophs synthesize organic compounds from (inorganic) carbon dioxide, a process known as carbon fixation. Photoautotrophs get the energy to perform these reactions from light. Chemoautotrophs get it from electron donors such as hydrogen sulfide and ammonia. Cyanobacteria, by contrast, convert nitrogen from the atmosphere into ammonia, a process known as nitrogen fixation.</span>
Answer: Ions are defined as atoms that have lost or gained an electron and have a charge.
Explanation: Ions are charged atoms. Ions can be negative or positive. When an atom looses one or more electrons, it becomes positively charged and a positively charged atom is called a cation. When an atom gains one or more electrons it becomes negatively charged and a negatively charged atom is called an anion.
<h3><u>Answer and explanation</u>;</h3>
- <u>According to the Law of conservation of mass; Mass cannot be created or destroyed in a chemical reaction.</u> The law of conservation of mass states that the total mass of substances taking part in a chemical reaction is conserved during the reaction. <u><em>For example in the equation;</em></u>
- <u><em>N2 + 8 H --> 2 NH3 + H2</em></u>
- <u><em>The number of hydrogen atoms and nitrogen atoms in the reactant side is equal to those on the product side.</em></u>
- Additionally; <em><u>the law of conservation of energy states that the total energy of an isolated system remains constant, that is it can not be created or destroyed, rather, it can only be transformed or transferred from one form to another.</u></em>
