Hint: Any process that is commonly exhibited by living organisms on a daily basis for carrying out daily metabolic processes can be termed as a life process. Such a phenomenon is common to both plants and animals.
Complete Answer
Let’s study each of the options given above in detail to find the correct option.
Excretion is the method by which animals get rid themselves of waste products and of the nitrogenous by-products of metabolism. It is common to both plants and animals. Through excretion organisms control osmotic pressure—the balance between inorganic ions and water—and maintain acid-base equilibrium. Waste products like $CO_2$ must be removed. If they're allowed to accumulate they cause poisoning which slows down vital chemical reactions.
Respiration is a metabolism that happens to all organisms. It's a biochemical process that happens within the cells in the form of certain chemical reactions. During this process, the energy (ATP-Adenosine triphosphate) is produced by the breakdown of glucose which is further employed by cells to perform various functions. Respiration consists of 4 distinct processes:
External Respiration: Exchange of gases between environment and body.
Pulmonary Ventilation: Moving air into and out of the lungs.
Transport: Transport of oxygen and $CO_2$ between the lungs and tissues.
Internal Respiration: Diffusion of gases between the blood of the systemic capillaries and cells.
Photosynthesis is another life process that is followed only by plants. Plants are autotrophs, which suggests they produce their own food. They use the method of photosynthesis to rework water, sunlight, and $CO_2$ into oxygen, and starch that the plant uses as fuel. It's the prime source of oxygen and energy for all living organisms.
Therefore, we can say that option D is the correct option.
Note:
Several factors can affect the speed of photosynthesis. They are:
1. Light intensity
2. Carbon dioxide concentration
3. Temperature
