The carbon that plants need for photosynthesis comes from (carbon dioxide gas in the atmosphere)
The rest of the
plasma fluid is reabsorbed into the blood stream. This comprises of the nutrients
and water. The unwanted materials i.e. solutes, water etc do concentrate to
form the urine and the other filtrated products are therefore reabsorbed.

Answer:
The correct option is this: A specific enzyme removes the hydrogen from the monosaccharide and the hydroxide from the polysaccharide, creating a bond between the two and creating a water molecule.
Explanation:
The process by which a monosaccharide molecule is added to an existing polysaccharide in biological systems is called CONDENSATION POLYMERIZATION.
During the process of condensation, an hydrogen atom and an hydroxide molecule from the reactants come together to form a water molecule; this leads to the formation of covalent bond between the reactants.
Condensation reaction is used in living organisms to produce complex macro molecules such as carbohydrates, proteins and lipids, which are needed by the body for health growth.
Remember, condensation reaction always results in loss of water molecules and formation of more complex molecule. One example of monosaccharide is glucose while cellulose (found in plants) and starch (found in animals) are examples of polysaccharides.
(English )Is it correct to say that energy follows a linear flow in the food sections, while nutrients are constantly recycled? Explain.
(Portuguese) É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.
Answer: <u>Yes</u>.
Responder: <u>Sim.</u>
Explanation: (*English) A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
(*Portuguese) Uma cadeia alimentar é uma sequência linear de organismos através dos quais nutrientes e energia passam enquanto um organismo come outro; os níveis na cadeia alimentar são produtores, consumidores primários, consumidores de nível superior e, finalmente, decompositores.
