Biology in SSS 2 focuses on life processes, ecosystems, and the anatomy of organisms.
This article outlines the scheme of work for the subject, covering topics like the respiratory system, reproduction in plants and animals, and ecological management.
Each term is organized to provide a comprehensive understanding of biological systems and their functions.
You also find a list of recommended textbooks to support further exploration of these topics.

RECAP
SSS 2 Biology offers a detailed exploration of life processes and ecosystems.
In the first term, you cover aquatic and forest habitats, along with digestion and circulation in animals.
The second term brings you into the realm of respiration, nitrogen cycling, and ecological management, while the third term focuses on plant reproduction, homeostasis, and sensory organs.
With the aid of recommended textbooks, each topic enhances your understanding of biological systems and their functions.
