Plants and algae use the sunlight to make organic matter from carbon dioxide and water. this establishes the beginning of energy flow through almost all food webs
Question:Does your body get all its energy from the sun?
Answer: Yes, the body does get all the energy from the sun. The body obtains energy by consuming and digesting food that the plant or animal has been going through CR. When we eat animals that eat plants, the energy from CR transfers to the consumers.
In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.
ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.
Answer:
Photosynthesis is a process whereby plants uses sunlight to prepare their own food using sunlight and without energy such as heat cannot perform its functions.
<h2>Answer </h2>
Option D - The Linnaean system of classification used a nested hierarchy to sort organisms into groups based on similarities and differences in their characteristics. kingdom → phylum → class → order → family → genus → species.
<u>Explanation</u>
The family is missing from the Linnaean system of classification that is used for nested hierarchy. Carolus Linnaean worked for the taxonomy. It is the system of classifying and naming organisms. This system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species. Linnaeus presented us with a uniform way to identify species called binomial nomenclature.
