What are the nephron?
Nephrons are the functional unit of the kidney. There are about two million nephrons in each of our kidneys. Each nephron has a network of glomelural capillaries called glomerulus where blood filtration occurs, and the renal tabule which is where the filtered fluid is converted to urine.
How they work?
The nephrons act as a filter, cleaning our blood. Unwanted metabolites like urea and creatinine are taken from the blood, as well as high amounts of sodium. The filtered fluid flows from inside Bowman's capsule (epithelial cells surrounding the glomerulus) and from there into the proximal tubule (see attached figure at the end). From the tubule, fluid flows into several other ducts until it reaches the ducts where collectors will empty into the renal pelvis.
Answer:
The correct answer is-
1. Photosynthesis- Carbon dioxide is a reactant, Oxygen is a product, Carried out in plants, Produces usable energy source.
2. Respiration- Carbon dioxide is a product, Oxygen is reactant, Carried out in animals, Produces usable energy source.
Explanation:
Photosynthesis is a complex process which takes place in the green plants which synthesize the energy molecule called glucose. The reaction takes place in the presence of sunlight combining the carbon dioxide and water forming the glucose and oxygen gas.
Respiration is a complex process which involves the breakdown of the glucose molecule in the presence of oxygen and forming the energy molecule called ATP which is utilized in the metabolic reactions. The complex process releases carbon dioxide.

A gymnosperm is a woody tree like a fir tree. It does not bear flowers or fruit. Its seeds are naked, as they are not covered by a fruit wall and are arranged in a cone-like structure. </span>
