Explanation:

Plant and animal fibers are both considered natural fibers because they are obtained directly from living organisms.

Plant Fiber:
- Plants provide us with various types of fibers that can be used to make fabrics and other materials.
- Examples of plant fibers include cotton, jute, hemp, flax, and sisal.
- These fibers are obtained from different parts of the plants, such as the seeds (cotton), stems (jute, hemp, flax), and leaves (sisal).
- Plant fibers are known for their strength, flexibility, and breathability, making them suitable for a wide range of applications.

Animal Fiber:
- Animals also produce fibers that can be used for various purposes.
- Examples of animal fibers include wool, silk, and fur.
- Wool is obtained from sheep and other animals like goats and rabbits. It is known for its warmth and softness.
- Silk is produced by silkworms and is highly valued for its smooth texture and lustrous appearance.
- Fur is the hair of animals like mink, fox, and beaver, and it is used for making warm and luxurious garments.
- Animal fibers are generally soft, insulating, and comfortable to wear.

Natural Fiber:
- Both plant and animal fibers are considered natural fibers because they are derived from living organisms.
- Natural fibers have been used by humans for thousands of years to make clothing, textiles, and other products.
- They are renewable resources and are biodegradable, making them environmentally friendly compared to synthetic fibers.
- Natural fibers also have unique properties and characteristics that make them suitable for different applications.

Conclusion:
- Fibers obtained from plants and animals are collectively known as natural fibers.
- These fibers have been used by humans for centuries and continue to be valued for their properties and sustainability.
