Hello kids, in this lesson we are going to talk about ecosystems.

2
00:00:07,419 --> 00:00:13,880
There are many different ecosystems around the world, but what is an ecosystem?

3
00:00:15,039 --> 00:00:25,280
Well, it's very easy. An ecosystem is an area where living and non-living things live and interact among them.

4
00:00:25,280 --> 00:00:34,460
An ecosystem can be as big as an ocean and as small as a little pond.

5
00:00:35,640 --> 00:00:40,820
We have said that there are living and no living things in an ecosystem.

6
00:00:42,000 --> 00:00:52,439
Well, living things are also called biotic factors, like the plants and animals that we can see marked with an arrow in this picture.

7
00:00:53,219 --> 00:01:06,280
No living things are also called abiotic factors, like water, rocks, sand, etc., that are marked with an arrow in the picture.

8
00:01:07,200 --> 00:01:12,239
Here we can see more examples of biotic and abiotic factors.

9
00:01:13,140 --> 00:01:17,359
Biotic factors or living things are the fauna and the flora.

10
00:01:18,340 --> 00:01:23,620
Fauna are animals, like a dog, a frog, a crab, a bee, etc.

11
00:01:24,620 --> 00:01:30,579
And flora are plants, like trees, buses, grass, flowers, etc.

12
00:01:31,500 --> 00:01:41,579
An abiotic factor, or no living things, are things like rocks, water, the sun, or buildings.

13
00:01:41,579 --> 00:01:49,579
In the next lesson, we will see the different types of ecosystems that are around the world.

14
00:01:49,579 --> 00:01:52,579
See you the next day!
