this is less than 4.1 ecosystems.
- 00:03 - 00:05
Everything is connected apart.
- 00:05 - 00:10
One. When we talk about this lesson, we we distinguish
- 00:10 - 00:13
between biotic and idiotic factors and ecosystem.
- 00:15 - 00:19
We're going to describe how a population differs from a
- 00:19 - 00:20
species were.
- 00:20 - 00:24
Then we're gonna explain how habitats are important for organisms.
- 00:25 - 00:27
Let's start with those objectives.
- 00:28 - 00:34
First of all, what is on ecosystem on ecosystem is
- 00:35 - 00:38
all of the organisms living in an area together with
- 00:38 - 00:39
their physical properties.
- 00:40 - 00:41
On oak forest is an ecosystem.
- 00:42 - 00:44
A coral reef is an ecosystem, By the way, these
- 00:45 - 00:47
two they can come to you in any multiple choice
- 00:47 - 00:52
questions. So coral, reef or forest, our ecosystem even a
- 00:52 - 00:53
vacant lot.
- 00:54 - 00:56
Also, this is one of the questions gonna have it
- 00:56 - 00:58
in any able to be choice questions in the future.
- 00:59 - 01:01
Uh, ecosystems are connected.
- 01:01 - 01:06
People often think off ecosystem as isolated from each other,
- 01:06 - 01:08
but ecosystems do not have clear boundaries.
- 01:09 - 01:12
Things move from one ecosystem into another.
- 01:12 - 01:15
Soil washes from a mountain into a lake.
- 01:16 - 01:19
Birds migrate from across the boundaries off miles on, pollen
- 01:20 - 01:22
blows from a forest into a field.
- 01:23 - 01:25
Let's introduce the comm parents off.
- 01:26 - 01:31
Ecosystem on ecosystem is made up off both living and
- 01:31 - 01:35
non living things we can call the living as biotic
- 01:35 - 01:39
factors are the living on once living things parts off
- 01:39 - 01:45
an ecosystem such as plants, animals, lives, waste even it's
- 01:45 - 01:46
a biotic thing.
- 01:47 - 01:50
A biotic factors are the non living parts off an
- 01:50 - 01:55
ecosystem such as air, water, rocks, sunlight, sanity, the PH,
- 01:56 - 01:57
the wind.
- 01:58 - 02:01
All of these are a biotic factors.
- 02:02 - 02:05
In order to survive, ecosystem needs certain basic components.
- 02:06 - 02:10
These are energy, mineral nutrients, carbon dioxide, water, oxygen and
- 02:11 - 02:11
living organisms.
- 02:13 - 02:16
Plants and soil are two off the obvious components off
- 02:16 - 02:17
most land ecosystem.
- 02:18 - 02:21
The energy is most ecosystem comes from the sun.
- 02:21 - 02:24
This is one of the multiple choices that you might
- 02:25 - 02:26
have it in any coming test.
- 02:27 - 02:29
To appreciate how all of the things in an ecosystem
- 02:30 - 02:30
are connected.
- 02:31 - 02:35
Think about how a car can work the engine a
- 02:35 - 02:39
little made up off hundreds off parts that all work
- 02:39 - 02:43
together. If even one part breaks, the car might not
- 02:44 - 02:49
run. Likewise, if one part often ecosystem is destroyed or
- 02:49 - 02:52
change, the entire system will be affected.
- 02:55 - 02:56
Now organization and on ecosystem.
- 02:58 - 02:59
Let's have a look.
- 02:59 - 03:02
The organization now, as you can see this flow chart
- 03:02 - 03:04
or conceptual chart graphic.
- 03:05 - 03:07
It can consist off the lowest one, which is the
- 03:08 - 03:10
organism is an individual living things.
- 03:11 - 03:15
You are an organism, as in an ant crawling across
- 03:15 - 03:18
the floor on ivy Plant on the wind.
- 03:19 - 03:19
Uh huh.
- 03:22 - 03:25
When Mel and a bacterium in your intestine organisms have
- 03:26 - 03:30
a rule, andan interact in an ecosystem shows how an
- 03:30 - 03:32
ecosystem fits into the organization.
- 03:33 - 03:33
Off living things.
- 03:34 - 03:37
A species is a group of organisms that can made
- 03:37 - 03:40
to produce fertile off offspring.
- 03:40 - 03:44
All humans, for example, are members off the species home
- 03:45 - 03:50
safest. All black widow spiders are members off the species.
- 03:51 - 03:52
Latour adults.
- 03:53 - 03:56
Now, when we talk about the population, members of the
- 03:57 - 03:59
species may not all live in the same place.
- 04:00 - 04:04
Filled mice in Maine on field mice in Florida will
- 04:04 - 04:08
never interact, even though they are members off the same
- 04:08 - 04:13
species on organism lives as part off a population of
- 04:13 - 04:16
population is a group off the same species that live
- 04:16 - 04:17
in the same place.
- 04:18 - 04:21
For example, all the field mice in a corn fields
- 04:22 - 04:23
make up one population.
- 04:24 - 04:28
Off field mice on important characteristic off population is that
- 04:29 - 04:33
its members usually breed with one another rather than with
- 04:33 - 04:38
a member off other populations lost another East Here.
- 04:39 - 04:46
When we talk about communities, we we say every population
- 04:47 - 04:48
is part of a community.
- 04:48 - 04:51
It means a group of various species that live in
- 04:52 - 04:54
the same place and interact with each other.
- 04:55 - 05:00
Ah, community differs from an ecosystem because community includes Onley,
- 05:00 - 05:05
the biotic components a bond community, for example, includes all
- 05:05 - 05:09
the population off plants, fish and insects and live in
- 05:09 - 05:10
and around the bond.
- 05:11 - 05:14
All of the living things in an ecosystem belong toe
- 05:14 - 05:16
one or more communities.
- 05:17 - 05:20
Communities differs in the type off members or number of
- 05:21 - 05:21
species they live.
- 05:22 - 05:25
Ah, land community is often characterized by the type of
- 05:26 - 05:27
plan that are dominant.
- 05:28 - 05:31
Let's say, let's talk about the plants, determine the other
- 05:31 - 05:35
organisms that can live in this even community.
- 05:36 - 05:39
The last thing here when we talk about habitat the
- 05:39 - 05:41
squatters mentioned above lived in a pine forest.
- 05:42 - 05:45
So happy that's the place where organisms live.
- 05:46 - 05:46
Ah, nde.
- 05:46 - 05:50
How their monkey habitat is the rain for four east
- 05:51 - 05:53
and the captives habitat is the desert.
- 05:54 - 05:54
Thank you for listening
