Basic Needs Of Living Things
Transcript
00:00Hi kids, today we will learn what are the basic needs of living things.
00:08So let's start.
00:13Living things need some basic things.
00:16That is air to breathe, water to drink, food to eat, shelter to live.
00:26Let's learn all the basic needs of living things one by one.
00:34First one is air to breathe.
00:36Kids, when we take in air from our nose or mouth, it is called breathing in.
00:45And when we take out air from our nose or mouth, it is called breathing out.
00:54Kids, we cannot hold our breath for long.
00:59That is, we cannot live without breathing.
01:03We, that is, humans, breathe through our nose.
01:09And we can also breathe through our mouth.
01:15Now let's see other animals.
01:18Dogs, do they breathe?
01:22Yes, they breathe, as they are living things.
01:28They also breathe through their nose.
01:31Now here is a cat.
01:34Does she breathe?
01:37Yes, cats do breathe.
01:40Cats also breathe through their nose.
01:44So animals breathe through their nose and can also breathe through their mouth.
01:52Now, fish is a living thing.
01:57Does it breathe?
01:59Yes, fish too breathe.
02:03Fish breathe through its gills.
02:06That is, fish have gills to breathe.
02:15Plants too are living things.
02:18Do they breathe?
02:20Yes, plants too breathe.
02:23And they breathe through tiny pores on leaves called stomata.
02:30We will learn more about it in higher grades.
02:34So kids, we learned that all living things need air to live.
02:40Living things cannot live without air, which is necessary for breathing.
02:48Now let's see another thing, which is a basic need of living things.
02:54Water to drink.
02:55Kids, do you drink water?
02:59Yes, and so many times a day.
03:03All living things need water to stay healthy.
03:07Do you water plants at home?
03:09Or your mom and dad gives water to plants.
03:13It is because plants too need water.
03:18All plants need water to make their food.
03:22Water enters the plants through its roots
03:26and then travels through tiny tubes in the stem to its upper part.
03:32That is, all the leaves, branches, and stems.
03:37Let's see this with an example.
03:40Here we have some white colored flowers and empty containers.
03:46We added some edible colors to water.
03:49Now keep them for a few days.
03:52After a few days, petals of each flower show the color added to its water.
04:02Flowers with pink water have pinkish tint.
04:06And flowers with yellow water have yellowish tint.
04:12All flowers have some shade, which is added to their water.
04:17That shows that water travels up the plant.
04:23All the plants, animals, and all of us need water to live.
04:29So water is one of the basic needs of all living things.
04:36Now let's learn another basic need of living things.
04:41Food to eat.
04:43We all eat food, don't we?
04:47Yes, we eat food, whatever we like daily, so many times a day.
04:54And also give food to our pets.
04:57We also give food to our plants.
05:01Food for plants is water and some nutrients from the soil.
05:06And we add water and manure to soil as food for plants.
05:13We give water and manure to the plants, which is their food.
05:21Food gives energy to all the living things to do work.
05:26If we don't eat food, we will fall sick.
05:30And we will not have the energy to do any work or play and enjoy.
05:38Also, food makes us grow big and strong.
05:43Now let's learn about another basic need of living things.
05:48That is shelter to live.
05:51All the living things need their home or shelter.
05:57Where do you live?
05:59You live in your home.
06:02That's your shelter.
06:04If it's very cold outside, you cannot survive for long outside.
06:10As you need warmth, and that is provided by your home.
06:15Or when it's raining outside, you cannot stand outside for long.
06:21You need your shelter.
06:23That is your home.
06:25You feel comfortable at your home.
06:28You have all the things you need only at your home.
06:32Every animal, too, needs its shelter.
06:35If it's very cold outside, or hot outside, or raining outside,
06:42animals need their shelter.
06:45So we make a shelter for our pets, too.
06:50Like this is a small house for a cat.
06:54And this is a kennel for a dog.
06:59This is a coop for a hen.
07:02Likewise, birds make their own nests to live.
07:08That's their home or shelter.
07:12Fish live in a pond or aquarium at our home.
07:18That's their shelter or home.
07:21So every living animal needs a shelter, which is their home.
07:27Our shelter, or our home, protects us
07:31from heat, cold, wind, and rain.
07:36We feel safe and comfortable at our home.
07:41So kids, we learned the basic needs of living things, air,
07:47water, food, and shelter.
07:50Now you may go ahead and take a quiz to learn more.
07:54Bye-bye.
