Class 6 Science - WEST-BENGAL
Diversity in the Living World
The chapter Diversity in the Living World introduces Class 6 students to the incredible variety of plants and animals found on Earth. Students will explore how different living organisms adapt to various habitats like forests, deserts, and aquatic environments. We study the basic characteristics of living beings, such as growth, respiration, and reproduction, and learn how to classify them based on their features. This chapter is very important for the WBBSE board exams as it forms the foundational base for higher-class biology, frequently featuring in short-answer questions, identification tasks, and descriptive questions about habitats and adaptations.

Frequently Asked Questions
What is the difference between biotic and abiotic components?
Biotic components are all the living things in an ecosystem like plants and animals, while abiotic components are the non-living things like sunlight, water, air, and soil.
Why do cactus plants have spines instead of leaves?
Cacti have spines to reduce the loss of water through transpiration in desert conditions and to protect themselves from grazing animals.
How do fish breathe underwater?
Fish have special organs called gills that help them take in oxygen dissolved in water.
