In this is we going to learn about food variety, food materials and sources, plant parts and animal products as food, what do animals eat?

What did you eat at home today? Find out what your friend ate today. Did you eat the same kind of food yesterday and today? We all eat different kinds of food at different times, isn’t it?

Food  a fact of life. We all need to eat and drink everyday. To grow, to energy, to be healthy. We need a range of different types of food.
Food we eat- fruits, vegetables, cereals, pluses, nuts, healthy food and junck food. They provide us a lot of carbohydrates, proteins and vitamin.

Fruit is a part of plant which contain seed. fruits are liked and eaten by many people. Fruit helps to stay strong and healthy. They gives us lot of vitamin.

Cereals are rich in nutrients. they  grown from grass type of plants. They are high carbohydrates, proteins, and minerals.We make idli, dosa, rotis and bread.

Pluses are rich in nutrients. They are grown in climber type plants. They are rich in proteins.We make dal, sambar, curry with them.They help us to grow strong.ex:bean, black grams etc.

Nuts are fruits with hard cover shell. sometimes dried seeds are also called nuts. Nuts give us a lot of energy. They are a healthy snack. ex; almonds, chesews.

Think about rice cooked at home. We take raw rice and boil it in water. Just two materials or ingredients are needed to prepare a dish of boiled rice.

On the other hand, some food items are made with many ingredients. To prepare vegetable curry, we need different kinds of vegetables, salt, spices, oil and so on.

Healthy eating means eating a variety of foods that give you the nutrients you need to maintain your health, feel good, and have energy. These nutrients include portein, carbohydrates, fat, water, vitamins, and mineral.

It may be easy for us to guess the sources of some of the ingredients that we listed in Fruits and vegetables, for instance. Where do they come from? Plants, of course! What are the sources of rice or wheat? You may have seen paddy or wheat fields with rows and rows of plants, which give us these grains.

A plant or a part of a plant is used for food is called as fruits and vegetables.

Junk food always consists of extra fats and calories. It is very hard to digest it containing high levels of calories from sugar or fat with little protein, vitamins or minerals.

We need lots of different foods to eat. We eat bread puris, idllis egg and milk in the morning breakfast. We take rice, dal, curry, curd in lunch time. We take chapattis, fruits and vegetables salads a very light food in dinner time.

And we get food items from some animals like milk, eggs, meat, chicken, fish, prawns, beef, pork and such others, which come from animals.

All living thing need food to grow, to energy, to healthy. Eating fruit and vegetables can help protect against some diseases including diabetes. 

 Plants are one source of our food. Plants store food material in different parts such as roots stems, branches, leaves, flowers fruits, seeds etc. We eat many leafy vegetables. We eat fruits of some plants. Sometimes roots, sometimes stems and even flowers.

Roots of some plants produces vegetables like carrot, raddish, beetroot, etc.

some vegetables such as sugarcane, potato, onion, ginger are the food made by the plant is stored in stem.

 In some plants such as cabbage, spinach and garden leaves the food is stored in leaves.

Some fruits are fleshy and juicy to eat. We get fruits such as mangoes, grapes, banana are the food made by the plant stored in fruits.

Some plants have two or more edible (eatable) parts. Seeds of mustard plants give us oil and the leaves are used as a vegetable.

Can you think of the different parts of a banana plant that are used as food? Think of more examples where many parts of a single plant are used as food.

Bees collect nectar (sweet juices) from flowers, convert it into honey and store it in their hive.

Flowers and their nectar may be available only for a part of the year. So,
bees store this nectar for their use all through the year. When we find such a beehive, we collect the food stored by the bees as honey.

Human beings depend on plants and animals for their food and other needs and so are animals on plants. We depend on non-living things also. Air, water and soil are the non-living . living things depend on non-living things for their existence.

Animals directly are indirectly depend in plants for their food. animals depends on plants for food, oxygen and shelther.

Children have you seen some animals eating only plants. These animals are called herbivores. Herbivores  such as cow,dogs camels, and deer eat grass.
 Herbivores have sharp and broad front teeth to bite the grass. Their  back teeth are flat this help to chew food.

Some animals eat only flesh of other animals. These animals are called carnivores. Carnivores such as lion, tiger, wolf and dear are eat flesh of other animals.Carnivores have sharp pointed front teeth. Their back teeth are flat this help to chew food.

 Some animals eat both plants and vegetables. These animals are called omnivores. Omnivores such as human being, bear etc eat both plants and animals.
