Here are the important topics that students should study from the chapter "The Living Organisms — Characteristics and Habitats" along with a brief summary for each:
1. Organisms and the Surroundings Where They Live:
– Paheli and Boojho observe different organisms in various locations they visit, noting the diversity in plants and animals based on surroundings.
2. Habitat and Adaptation:
– Focuses on the variety of organisms in different habitats like the desert and sea, discussing how their features help them survive, leading to the concept of adaptation and habitats.
These topics cover the essential concepts in the chapter about the characteristics of living organisms and how their habitats influence their survival and adaptation.
What examples of living organisms did Paheli and Boojho encounter in their various trips?
Camels in the mountains, cactus plants in the desert, crabs at the sea beach, fish caught by fishermen, and ants present in all locations.
Describe the differences in surroundings between the sea and the desert as mentioned in the chapter.
In the sea, plants and animals are surrounded by saline water and use air dissolved in water. The desert has very little water, extreme temperatures (hot in the day and cold at night), and the organisms live on desert soil and breathe air from the surroundings.
Explain how the body structure of a camel helps it survive in desert conditions.
Camels have long legs that keep their bodies away from the hot sand. They excrete small amounts of urine, have dry dung, and do not sweat much, allowing them to conserve water and survive for days without drinking.
Define 'adaptation' and provide an example of adaptation mentioned in the chapter.
Adaptation is the presence of specific features or habits in an organism that help it live naturally in a specific place. An example is how fish have gills to use oxygen dissolved in water, aiding their survival underwater.
Explain the difference between terrestrial and aquatic habitats with examples.
Terrestrial habitats are land habitats like forests, grasslands, and deserts, while aquatic habitats are water habitats like lakes, rivers, and oceans. Animals like tigers and elephants live in terrestrial habitats, while fish and whales live in aquatic habitats.
