All living organisms are capable ofa)Reproduction and Photosynthesisb)Locomotion and Respirationc)Excretion and Locomotiond)Respiration and ExcretionCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

All living things excrete to remove waste material from the body. Living beings have the ability to give birth to their young ones through the process of reproduction. All living beings require energy to perform different metabolic activities, and they gain energy from food/ nutrition.
Respiration is essential for survival of living organisms. It releases energy from the food. The oxygen we inhale is used to breakdown glucose into carbon dioxide and water. Energy is released in the process.

Answer

This question, let I tell you option by option, first one  Reproduction and photosynthesis ,photosynthesis is not done by all living organism it is only  done by autotrophs ,reproduction is not done by many of the organism like mule , sterile couples e. t. c.  Locomotion is not done by many animals like sponge which are not motile but when we talk about Respiration it is done by all living organism weather  it is by  aerobic or anaerobic method  and Excretion is also done by all living organism be it directly by the skin or by the help of any organ.So,in this ques only respiration and Excretion is done by all living organism

Answer

This question ans (b)

Answer

Understanding the Characteristics of Living Organisms
All living organisms exhibit a set of fundamental characteristics that define life. Among these, respiration and excretion are essential processes that all organisms perform.
Respiration
- Definition: Respiration is the biochemical process by which organisms convert nutrients into energy.
- Importance: This energy is crucial for maintaining cellular functions, growth, and reproduction.
- Types: Organisms utilize aerobic (with oxygen) and anaerobic (without oxygen) respiration based on their environment.
Excretion
- Definition: Excretion is the process of removing waste products resulting from metabolic activities.
- Importance: It helps in maintaining homeostasis and preventing the accumulation of toxic substances in the body.
- Examples: Different organisms have various excretion methods, such as kidneys in mammals, gills in fish, and simple diffusion in unicellular organisms.
Why Not the Other Options?
- Option A (Reproduction and Photosynthesis): While reproduction is a characteristic of all living organisms, photosynthesis is specific to autotrophic organisms (like plants).
- Option B (Locomotion and Respiration): Not all organisms are capable of locomotion; many, such as plants and certain bacteria, are stationary.
- Option C (Excretion and Locomotion): Again, locomotion is not a universal trait among all living organisms.
Conclusion
Ultimately, respiration and excretion are universal life processes that highlight the fundamental nature of living organisms. Understanding these processes is essential for studying life sciences, especially in contexts like NEET preparation.
