Audio Transcript Auto-generated

• 00:01 - 00:02

  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
