00:00Living things need some basic things.
00:04That is air to breathe, water to drink,
00:09food to eat, shelter to live.
00:14Let's learn all the basic needs of living things one by one.
00:22First one is air to breathe.
00:24Kids, when we take in air from our nose or mouth,
00:30it is called breathing in.
00:34And when we take out air from our nose or mouth,
00:38it is called breathing out.
00:42Kids, we cannot hold our breath for long.
00:47That is, we cannot live without breathing.
00:52We, that is, humans, breathe through our nose.
00:57And we can also breathe through our mouth.
01:03Now let's see other animals.
01:07Dogs, do they breathe?
01:11Yes, they breathe, as they are living things.
01:16They also breathe through their nose.
01:20Now, here is a cat.
01:23Does she breathe?
01:25Yes, cats do breathe.
01:29Cats also breathe through their nose.
01:33So animals breathe through their nose
01:36and can also breathe through their mouth.
01:41Now, fish is a living thing.
01:46Does it breathe?
01:48Yes, fish too breathe.
01:52Fish breathe through its gills.
01:56That is, fish have gills to breathe.
02:03Plants too are living things.
02:07Do they breathe?
02:08Yes, plants too breathe.
02:12And they breathe through tiny pores
02:14on leaves called stomata.
02:18We will learn more about it in higher grades.
02:22So kids, we learned that all living things
02:26need air to live.
02:29Living things cannot live without air,
02:33which is necessary for breathing.
02:37Now let's see another thing,
02:39which is a basic need of living things.
02:42Water to drink.
02:44Kids, do you drink water?
02:47Yes, and so many times a day.
02:51All living things need water to stay healthy.
02:56Do you water plants at home?
02:58Or your mom and dad gives water to plants.
03:02It is because plants too need water.
03:07All plants need water to make their food.
03:11Water enters the plants through its roots
03:15and then travels through tiny tubes
03:18in the stem to its upper part.
03:21That is, all the leaves, branches, and stems.
03:26Let's see this with an example.
03:29Here we have some white colored flowers
03:32and empty containers.
03:34We added some edible colors to water.
03:38Now keep them for a few days.
03:41After a few days, petals of each flower
03:44show the color added to its water.
03:51Flowers with pink water have pinkish tint,
03:55and flowers with yellow water have yellowish tint.
04:00All flowers have some shade,
04:03which is added to their water.
04:06That shows that water travels up the plant.
04:11All the plants, animals, and all of us need water to live.
04:17So water is one of the basic needs of all living things.
04:25Now let's learn another basic need of living things.
04:30Food to eat.
04:32We all eat food, don't we?
04:35Yes, we eat food, whatever we like daily,
04:40so many times a day, and also give food to our pets.
04:46We also give food to our plants.
04:50Food for plants is water and some nutrients from the soil.
04:55And we add water and manure to soil as food for plants.
05:02We give water and manure to the plants, which is their food.
05:09Food gives energy to all the living things to do work.
05:14If we don't eat food, we will fall sick,
05:18and we will not have the energy to do any work,
05:23or play, and enjoy.
05:27Also, food makes us grow big and strong.
05:31Now let's learn about another basic need of living things.
05:37That is shelter to live.
05:40All the living things need their home or shelter.
05:45Where do you live?
05:47You live in your home.
05:50That's your shelter.
05:53If it's very cold outside,
05:55you cannot survive for long outside,
05:59as you need warmth, and that is provided by your home.
06:04Or when it's raining outside,
06:06you cannot stand outside for long.
06:10You need your shelter.
06:12That is your home.
06:13You feel comfortable at your home.
06:17You have all the things you need only at your home.
06:21Every animal too needs his shelter.
06:24If it's very cold outside, or hot outside,
06:28or raining outside, animals need their shelter.
06:33So we make a shelter for our pets too.
06:39Like this is a small house for a cat.
06:43And this is a kennel for a dog.
06:48This is a coop for a hen.
06:51Likewise, birds make their own nests to live.
06:57That's their home or shelter.
07:01Fish live in a pond or aquarium at our home.
07:07That's their shelter or home.
07:10So every living animal needs a shelter,
07:14which is their home.
07:16Our shelter or our home protects us
07:20from heat, cold, wind, and rain.
07:25We feel safe and comfortable at our home.
07:30So kids, we learned the basic needs of living things,
07:34air, water, food, and shelter.
