ICSE Class 6 Biology, Unit 5: Adaptation

What this unit aims at

All living organisms, for their survival, need to be well-suited to the environment in which they live. To attain this, organisms develop some features which help them to survive and reproduce in their environment. Features so acquired help organisms to adapt to their particular environments. This theme enables children to understand how some plants and animals are adapted to live and survive in dry habitats, whereas others can live in water or on mountains, or fly in air.

Your child should be able to

• define adaptation and habitat
• recall the names of plants and animals, and their adaptations studied in earlier classes
• record the adaptations shown by plants and animals living in desert/ aquatic conditions
• prepare a list of plants and animals occurring in different habitats with their common names and adaptations

Key concepts in this unit

• Habitat – definition.
• Adaptations of plants and animals to the following habitats along with characteristics and examples:
• Aquatic habitat- floating, submerged and fixed plants; adaptations in fish.
• Desert - adaptations in cactus as desert plant and camel as desert animal.
• Mountain – adaptations in trees like Pine and Fir; mountain goat
• Air - adaptation for flight in birds, aerial plants.
