Answer:
Collagen fibers
Explanation:
Cartilage is the connective tissue found in the mammalian group of animals and is composed of the collagen fibre made by the chondrocytes which occur at the scattered sites.
The fibrocartilage is one of the types of cartilage present in the intervertebral disks and helps provide the tensile strength and help absorb the shock in the spine.
The extracellular matrix of fibrocartilage is enriched with the collagen fibres which provides toughness and great tensile strength to the cartilage.
Thus, Collagen fibres are the correct answer.

Deforestation leads to fewer plants being available to conduct photosynthesis. Less oxygen is available for cellular respiration is a possible effect on the remaining plant populations.
<u>Explanation:</u>
- Deforestation and Photosynthesis are related to each other. Because if Deforestation occurs more photosynthesis will reduce.
- Cutting and burning down of the trees causes deforestation as it affects photosynthesis. Plants prepare food using photosynthesis. 
- The plant takes carbon-di-oxide for the preparation of food and releases oxygen. Oxygen is required for every living thing in the world.
-  As now World goes on deforestation and it should be seriously stopped.
