Hello everyone and welcome back from March break.

You all look excited. So you look tiny bit tired. That's completely okay.

We'll ease our way into work.

We won't be doing the hard work today to take a deep breath.

Okay,

now before we get into work I love to know what you all did over the March break,

something different, something interesting.

Anything you want to share of course with a raise of hands,

we need to respect everybody's time and what they have to say.

Okay,

let's hear it,

wow, that's interesting. Okay, thank you for sharing.

Okay.

Mhm.

Okay,

thank you for asking what I did over the March break.

Um honestly mine must just spend,

you know relaxing babysitting my nieces because I have loads of them.

So it was mostly just spending um you know time with the family. Okay,

okay.

Before we get into this

um

are we familiar with

what an ecosystem is?

Okay,

mm hmm. It's completely okay because we still don't know what an ecosystem is.

We haven't learned it. So there's no need to be shy.

Mhm.

Okay,

now quietly in your heads think of all the

living things and non living things around us.

Okay.

Mhm

No.

Mhm.

Okay,

now

moving on to what an ecosystem is. Let's see what an ecosystem really is.

So

an ecosystem is a community of plants and animals that interact in the same area.

Okay, so an ecosystem, what is it?

It's a community of plants and animals that interact in the same area.

Okay, so ecosystem basically is a community.

It's a place it has living things and non living things. Okay.

They exist together in an environment. Okay,

ecosystem

is a community of plants and animals and other beings that interact in the same area.

Okay.

To break it down further to make it even

easier to understand its any environment that basically has

living things and non living things and they actually

exist together not separately to exist and work together.

Okay, so now neatly in your notebooks,

let's write these down.

Okay,

ecosystem

basically an environment.

Okay, it's an environment. What does it have

living things

and non living things? Are they just separately just existing there

in an ecosystem? It's a system they're working together.

They're existing together in that same environment.

Living things and non living things. Okay.

Now can we think of places that have

um like ecosystem.

Let's think ecosystem,

we still don't know what really an ecosystem we're still learning.

So do we have examples in our head what an ecosystem could be examples

with a raise of hands.

Mhm.

Okay, good job. Okay.

Okay so a swamp. A prairie and oceans and the forests are all examples of ecosystems.

Okay. And these are just some of the examples.

There's so many different ecosystems around us. Okay.

Um and an ecosystem usually contains many different kinds of life.

Okay for example with a swamp. I know we've

all watched Shrek

um with the swamp that Shrek used to live in.

I'm sure it didn't have just you know living things, you know,

the toads or like those fish that Shrek used to eat.

We all had non living things in that swamp right? There were um you know, tiny rocks.

The water is water and living things. No, it's not right.

So swamp, it's an example of an ecosystem.

It's an environment where non living things are

existing and living things are existing together.

Okay.

Um an ecosystem of course usually contains many different kinds of life.

Um A grassland for example is just an ecosystem. Um it contains more than just grass.

When you hear the term grassland you're thinking just grasp. Okay.

No, of course it contains, you know, more than just grass and includes other plants,

mammals, insects, growth worms, many tiny living things.

Um you know in the soil. Um and it also has many non living things, right?

A grassland wouldn't just have living things that would have known living things.

It's an ecosystem.

Okay,

so biotic versus a biotic. Before we get into that. Can we all together say biotic.

So we know how to pronounce that?

I used to have difficulty saying that when I was a kid and that's completely.

Okay, so can we all say biotic?

Mm hmm. Can we all say a biotic.

Okay,

so biotic elements are living things in an ecosystem.

Okay. For example, plants and animals either.

Just some of the examples, of course there are different types of plants,

different types of animals, different organisms that are alive

um Okay so biotic and a biotic when

we look at an ecosystem there biotic elements living

in an ecosystem and what are those biotic elements?

They're living things? And examples being plants and animals.

Okay.

Um when we learn new things we sometimes tend to forget the

previous thing because we're still getting used to the term ecosystem.

Let's get back to what an ecosystem is, ecosystem is an environment, what is

type of environment?

Well different kinds of environment um doesn't ecosystem have living things? Yes

but does it also have non living things? Yes. Are they separate?

No the living things and the non living things in ecosystems are existing together.

What's another word for um living things in an ecosystem, biotic

biotic elements are living things in an ecosystem.

Okay

now

a biotic elements are non living things in an ecosystem example sunlight, air rain,

snow, rocks, water.

So what's another word for non living things in an ecosystem?

A biotic, So a biotic or non living and examples could be sunlight, air, rain, snow,

rocks, water, mountains, all these things right

now it's time to use our big brains. Okay let's think of an ocean.

And of course ocean is an ecosystem. Yes. Yes. Yes. Yes.

The notion is an ecosystem and before we go on the board I want you all to first think

um of living. So biotic and non living a biotic things in the ocean. Okay

and once you've um thought about it on your own.

I want like a raise of hands so I can know who's done thinking and is

ready to come on the board and of course um we're going to be you know

respectful. We're not going to be running around the classroom

so and if you're okay with sharing both a biotic and biotic um examples in the ocean

please feel free to do so if you only have one example

of just biotic or a biotic you can do so no pressure.

Okay come on. Yes. Okay.

Okay come on mm hmm.

Okay.

Yeah.

Perfect, perfect, perfect, perfect.

Mhm.

Okay

wow these are good examples you all came up with. Let's go over these.

So biotic we have plants in the ocean. We have fish. We have fun guy, we have algae.

Um and we have bacteria. Okay and now let's look at the antibiotic lists.

We all came up with. Okay stone for sure, sunlight. Perfect temperature.

Who thought of that? Good job.

Okay nutrients. Good word. Wind. Yes. Good job. Okay

now living parts of an ecosystem. Okay.

They're living parts in an ecosystem and we have organisms.

So the living you know beings um to the animals.

We have species. Okay we have population and we have community.

Let's neatly write these down. Do not hesitate. We still don't know what these are.

We're gonna learn in the next slide. Take a deep breath.

Okay neatly write that down.

Okay,

okay, so living parts of an ecosystem, organism. A living thing species.

So organism we all know, um it's a living thing.

It could be anything, it could be a bird, it could be a fish, it could be um

a mammal. It could be a wrap top, any type of animal and type of living organism.

Okay, now species can go to species.

Okay,

it's a group of similar organisms that can mate

and reproduce more of the same type of organism.

Okay, so a species of lions.

Okay, they can, you know, come together mate and we produce more lions. Okay,

okay.

And then we have population, It's a group of organisms in the same species

in a given area. For example, a population of um white lions in um South America.

Okay,

Population to a group of lions.

Okay. Because it's the same species. A group of white lions.

Okay. In North America. Okay,

Population two group,

it's a group of those organisms as a group

of those living things and they're the same species.

Species are

those same animals that can come together and reproduce more of the same species.

More of the same organism.

Okay, so population is a group of organisms of the same species and given area.

Okay, so a population to a group of white lions in

South America.

Okay,

A community is a group of populations of different species in a given area.

So what's a community?

It's a group of populations of different species with different animals?

Of, you know, different groups of animals in a given area. So a community could be um,

species of flying species of monkey, Species of different

um, types of animals in perhaps a forest. Okay,

that's a community.

And of course

we're living things. We have different needs.

Okay, so as as humans, first of all, we cannot exist without oxygen.

We wouldn't be able to exist. We need that to survive.

So we have multiple needs, not just oxygen.

So what are some of the things all living things need?

Okay, it's a place to live, habitat and environment live. Okay,

so habitat is important. We have habitat.

That's some of the, um, that's one of the things that all living things need to exist.

Okay, so habitat, we need sunlight.

Um, if we're looking at plants, plants are living things. They need sunlight.

We all need sunlight.

We need air,

water,

food, ideal temperature range. For example, us as humans,

we're part of a bigger ecosystem. Um, we need an ideal temperature range.

We won't be able to survive if it's too hot.

If it's too cold, we need that ideal temperature range for us to

um,

you know, exist and you know, survive.

So from these last things are these living, are these things living things,

all these needs and things that living things need.

Are they living things to sunlight? A living thing?

This food and living thing?

Mm hmm.

No, they're not living things.

And why is that

it's because of an ecosystem, living things and non living things exist together?

They need those living living things need those non

living things to exist to make that ecosystem work.

Okay,

so a biotic elements influence which biotic elements can survive in certain areas.

Right. So for examples, why can't kangaroos live in Canada?

Right?

It's because.
