Identifying Non-Living Organisms
In the options provided, we need to discern which item is non-living. Let’s analyze each option:

Options Overview
- (a) Cow: Cows are living organisms. They belong to the animal kingdom and possess characteristics such as growth, reproduction, and metabolism.
- (b) Tree: Trees are also living organisms. They are part of the plant kingdom and engage in photosynthesis, growth, and reproduction.
- (c) Human Beings: Humans are living organisms as well. They exhibit all characteristics of life, including growth, metabolism, and the ability to reproduce.
- (d) Table: A table is a non-living object. It is an inanimate object made from materials like wood or metal and does not possess any biological processes or characteristics of life.

Conclusion
Based on the analysis above, the correct answer is:
- Table: It is the only non-living organism among the options listed. Unlike cows, trees, and humans, a table does not exhibit any life processes.
Understanding the distinction between living and non-living entities is crucial in biology. Living organisms grow, reproduce, respond to stimuli, and carry out metabolic processes, while non-living objects do not possess these characteristics.
