CBSE Class 6 Science Notes Chapter 1 Food Where Does It Come From?

• Growth : Food provides the necessary nutrients for growth and development. It is especially crucial for young organisms to support their rapid growth phases.
• Energy : Food is a source of energy that fuels various biological processes within the body. This energy is essential for organisms to carry out activities such as hunting, foraging, and reproduction.
• Tissue Repair and Replacement : The nutrients in food are used by the body to repair and replace damaged tissues. This process is crucial for maintaining the health and integrity of the organism's body.
• Immunity and Disease Resistance : Food plays a crucial role in boosting immunity and providing protection against diseases and infections. A well-balanced diet can help strengthen the body's immune system, making it more resilient to illnesses.

• Roots : Carrots, radishes, turnips, sweet potatoes, and beetroots are examples of roots that are commonly eaten.
• Stems : Stems of plants such as sugarcane and banana are also consumed either directly or processed into food products.
• Leaves : Lettuce, spinach, cabbage, coriander, mint, and basil are examples of leaves that are used in cooking and consumed for their nutritional value.
• Flowers : Certain plants produce edible flowers, such as cauliflower, broccoli, and banana flowers, which are used in various cuisines.
• Fruits and Seeds : Fruits and seeds of plants like mung beans, kidney beans, chickpeas, wheat, maize, and rice are rich sources of nutrients and form an essential part of the human diet.

• Animals that eat plants, such as cows, horses, and goats, have wide, flat teeth. These teeth are good for pulling plants from the ground and grinding them up.
• Cows and camels, which are herbivores, can bring food they've swallowed back to their mouths to chew it again. This helps them get most of the nutrients from tough-to-digest food like grass.
• Squirrels have sharp, wide front teeth (called incisors) in both jaws. They use these teeth to chew on things like nuts.
• Butterflies and hummingbirds, also herbivores, don't need to chew their food. They have mouthparts shaped like straws that they use to drink nectar from flowers.

• Animals that eat meat, such as lions and tigers, have sharp and pointed front teeth called canines. They also possess sharp claws and strong jaws that aid in ripping apart flesh.
• Birds that feed on meat, like eagles, have curved and pointed beaks designed for tearing flesh.
• Some meat-eating creatures like chameleons and frogs have long, sticky tongues which they use to capture insects.
• Meat-eating fish like sharks are equipped with numerous small, sharp teeth that enable them to bite off pieces of flesh.

• Animals such as bears and humans, who are omnivores, possess various kinds of teeth that aid them in consuming both plants and the flesh of other creatures.
• Similarly, omnivorous birds like crows have a sharp and pointed beak which assists them in eating a wide range of food

Benefits of CBSE Class 6 Science Notes Chapter 1

• Clarity of Concepts : These notes provide a concise and clear explanation of the fundamental concepts introduced in the chapter. For Class 6 students who are just beginning their journey into scientific learning, having clear explanations can lay a strong foundation for future studies.
• Structured Learning : The notes are usually organised in a structured manner, covering different aspects of the topic systematically. This structure helps students understand the flow of information and aids in better comprehension.
• Simplified Language : Science can often involve complex terminology and explanations, which might be overwhelming for young learners. CBSE Class 6 Science Notes are written in simplified language, making it easier for students to grasp concepts without feeling intimidated.
• Visual Aids : Many notes include diagrams, illustrations, and charts to supplement the text. Visual aids play a crucial role in enhancing understanding, especially for topics related to biology, where visual representation of concepts like plant parts or food chains can significantly aid comprehension.
• Quick Revision : As students progress through the academic year, they accumulate a vast amount of information. These notes serve as a handy tool for quick revision before exams or quizzes. They condense the key points from the chapter, saving time and effort for students.
• Homework Assistance : When students encounter difficulties with homework or assignments, referring to these notes can provide them with the necessary guidance. The notes often include examples and explanations that can help students tackle problems independently.
• Supplementary Resource : While textbooks are the primary source of information, supplementary resources like class notes can provide additional insights and perspectives. They can offer alternative explanations or examples that complement the textbook content, enriching students' understanding.
• Preparation for Competitive Exams : For students aspiring to pursue higher education or appear for competitive exams in the future, a strong foundation in science is essential. CBSE Class 6 Science Notes lay the groundwork for more advanced concepts that students will encounter in subsequent grades and examinations.
• Encourages Self-Study : With well-organised and comprehensive notes at their disposal, students are encouraged to engage in self-study. They can review the notes independently, reinforce their learning, and clarify doubts on their own, fostering a sense of independence and responsibility towards their education.
• Facilitates Conceptual Learning : Rather than rote memorization, these notes emphasise conceptual understanding. By explaining the underlying principles and mechanisms behind scientific phenomena, they encourage students to think critically and apply their knowledge to real-life situations.
