[ Green plants make their own food through a process called photosynthesis, using sunlight, carbon dioxide, and water to produce glucose and oxygen. Animals, including humans, cannot perform photosynthesis and must get their food by eating plants or other animals. We need food for energy and nutrients, which are necessary for our bodies to function, grow, and repair themselves. Ensuring everyone has enough food requires regular production, good management, and efficient distribution of food resources. Paheli and Boojho went to their uncle’s house during the summer vacation. Their uncle is a farmer.
One day they saw some tools like khurpi, sickle, shovel, plough, etc., in the field.]
Yes, I can recall how green plants synthesize their own food. Green plants make their food through a process called photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide from the air, and water from the soil to produce glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells, which contain a green pigment called chlorophyll that captures sunlight. The overall equation for photosynthesis can be summarized as follows:
Animals, including humans, cannot make their own food because they lack chlorophyll and the ability to perform photosynthesis. Instead, animals obtain their food by consuming plants, other animals, or both. Herbivores eat plants, carnivores eat other animals, and omnivores eat both plants and animals.
We need to eat food because it provides the energy and nutrients necessary for our bodies to function properly. Energy from food is used for various bodily functions such as:
- Digestion: Breaking down food into smaller molecules that can be absorbed and utilized by the body.
- Respiration: The process of converting glucose and oxygen into energy (ATP), carbon dioxide, and water.
- Excretion: Removing waste products from the body.
- Growth and Repair: Providing the building blocks for cells, tissues, and organs.
To ensure that a large population has enough food, it is important to have regular production, proper management, and efficient distribution of food resources. This involves agricultural practices, food storage and transportation systems, and policies that support food security and accessibility for all people.
