What is an ecosystem?

Hello. Today we're going to talk about our very first

lesson, which is what is an ecosystem.

So we're gonna start by defining the ecosystem.

An ecosystem is all the living and non living organisms

and one environment interacting.

As you can see in this picture, we can see

all types of different things that air interacting with each

other. The water and the fish, the wind and the

birds. We see the sun shining on all of our

plants. Um, this is a good representation, representation of an

ecosystem. But the key points that we need to pick

from this is that an ecosystem has a checklist.

And in that checklist, we need to look for the

environment, non living things and the living things.

So if we go back real quick, we can see

our environment is kind of a forced the area that's

kind of got this speech along it so we can

see our environment.

And then we're gonna look at non living things which

we can see.

We can see the water and we can see these,

you know, sun coming down on our living things, which

is our dear, are fox are fish in our birds.

So this picture, we have the whole ecosystem.

So the next we wanna look at climate.

So climate is the average weather conditions in an area

so more normal conditions.

So your location can actually help you determine your climate

So key points would be your location.

Are you in the mountains or in the desert?

Are you in the forest?

And then how often does this whether happen?

And then we can also and instead of climate, weaken

say a bio MME.

Now, ah, bio is a way to describe different regions

that have similar climates.

So these are all going to have similar type, whether

they're gonna have similar plants and animals, Um, that all

work together and our ecosystem.

So here's a little simplified infographic of the bios in

the United States.

Um, if you're in Indiana with me right now, you're

currently and it is It was forced bio.

But if you were in, say, Washington, you would be

in a coniferous forced.

So that's one way to look at your environment when

it comes to the ecosystem.

So next we're going to take a look at are

living in non living, So we need to determine whether

something's living or not living.

So living things need to respond to their environment.

So we we know that a tree soaks up water

and gives oxygen.

This is a tree responding to its environment.

A bee pollinates flowers and creates a high.

This is the be responding to the flowers, needing pollinated

and keeping this process of living going on.

But we also know that Iraq doesn't respond to anything.

I can poke a rock.

It's not going to do anything.

I can put it in water.

It's not going to do anything.

So this is a non living piece of our ecosystem.

So let's just do a quick little review a little

game. So can you guess which of these things are

living and not living?

I'm gonna go ahead and give you a few seconds

toe kind of decide.

Okay, well, I hope you have your answers.

We have water, we have a flower, and with even

a little be on it.

We have a snail and then we have the Mr

Happy son.

So let's go ahead and start with water.

As I mentioned before, water isn't going to respond to

anything the only thing is going to do is if

I put my hand in it.

It's gonna move less because I'm exerting a force on

it. So therefore, water is non living Now we can

go counterclockwise and look at our flower in R B.

You can actually see those two responding to each other.

The B is helping the flower pollinate, and then we

can go on tour.

It's now, so our snail, it responds to the environment

and it helps the environment.

So therefore, is a living thing.

And Mr Son, even though he's far, far away, he

doesn't respond in our environment in our ecosystem.

So therefore, it is non living.

So I hope you hope you guys got that right.

It's not.

Listen again and see if you can figure out why

they're living and non living.

Um, use this as an example.

So next we're gonna go to a local.

So I want you to get up and pause this

and go look outside.

Think of one for each of the following.

What you think of one living thing, One non living

thing, what the environment is like and what the climate
