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?
FOOD
VARIETY
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.
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.
FOOD
MATERIALS AND SOURCES
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.
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.
PLANT
PARTS AND ANIMAL PRODUCTS AS FOOD
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.
WHAT
DO ANIMALS EAT?
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.
