1
00:00:00,000 --> 00:00:06,099
Well, we're going to check now pages 60 and 61, okay?

2
00:00:06,519 --> 00:00:13,000
For that, before we're going to review a little bit of what we did yesterday, okay?

3
00:00:13,359 --> 00:00:20,079
So remember, all the living things in ecosystems interact with all the living things in different ways, right?

4
00:00:20,500 --> 00:00:23,660
Well, which are those relationships? Do you remember?

5
00:00:23,660 --> 00:00:38,600
some symbiotic relationships remember they depend on each other and competitive good

6
00:00:38,600 --> 00:00:43,280
can you tell me about some symbiotic relationships

7
00:00:43,280 --> 00:00:56,280
Commensalism, remember, one receives benefits and the other is unaffected.

8
00:00:56,280 --> 00:01:11,280
Parasitism, remember, one has benefits and the other is harmful.

9
00:01:11,280 --> 00:01:23,280
And the last one, mutualism. Both get a benefit, right?

10
00:01:23,280 --> 00:01:28,280
Alright, so we have competitive. Remember, competition.

11
00:01:28,280 --> 00:01:38,280
There are two or more organisms competing for the same resources, like water, food, light, space.

12
00:01:38,280 --> 00:01:47,280
And we have also predation. One is the predator, that is the hunter, and the other is the prey, that is the hunted.

13
00:01:47,280 --> 00:01:51,280
Alright? So we're going to see here. Number two.

14
00:01:54,280 --> 00:01:57,280
Which definition describes a relationship?

15
00:01:57,280 --> 00:02:03,280
We have A, B, and C.

16
00:02:03,280 --> 00:02:06,280
With this yesterday? No.

17
00:02:06,280 --> 00:02:10,099
All right.

18
00:02:10,620 --> 00:02:35,719
So, we have commensalism, parasitism, mutualism.

19
00:02:42,110 --> 00:02:45,509
So, also we have your giving and receiving.

20
00:02:47,090 --> 00:02:56,729
Receiving without giving.

21
00:03:00,280 --> 00:03:28,780
receiving or harming

22
00:03:28,780 --> 00:03:35,139
you're coming for a wrong

23
00:03:35,139 --> 00:03:39,539
check

24
00:03:39,539 --> 00:03:43,680
commensalism

25
00:03:43,680 --> 00:03:45,060
receiving, no

26
00:03:45,060 --> 00:03:48,699
commensalism, receiving without giving

27
00:03:48,699 --> 00:03:49,199
yes

28
00:03:49,199 --> 00:03:52,560
parasitism

29
00:03:52,560 --> 00:03:54,060
giving, no

30
00:03:54,060 --> 00:03:56,020
receiving and harming

31
00:03:56,020 --> 00:03:58,180
mutualism

32
00:03:58,180 --> 00:03:59,280
giving or receiving

33
00:03:59,280 --> 00:04:00,919
giving or receiving

34
00:04:00,919 --> 00:04:02,620
number

35
00:04:02,620 --> 00:04:05,259
number four

36
00:04:05,259 --> 00:04:13,979
relationship

37
00:04:13,979 --> 00:04:17,790
organism one

38
00:04:17,790 --> 00:04:21,620
organism one

39
00:04:21,620 --> 00:04:23,120
and organism two

40
00:04:23,120 --> 00:04:29,360
two

41
00:04:29,360 --> 00:04:46,850
commensalism

42
00:04:46,850 --> 00:04:47,569
remember

43
00:04:47,569 --> 00:04:58,740
so

44
00:04:58,740 --> 00:05:00,819
commensalism

45
00:05:00,819 --> 00:05:06,019
how do you say

46
00:05:06,019 --> 00:05:06,899
sigma de mass

47
00:05:06,899 --> 00:05:08,360
plus

48
00:05:08,360 --> 00:05:09,160
plus

49
00:05:09,160 --> 00:05:11,459
one

50
00:05:11,459 --> 00:05:12,639
a zero

51
00:05:12,639 --> 00:05:13,899
you obtain

52
00:05:13,899 --> 00:05:16,000
you obtain

53
00:05:16,000 --> 00:05:17,079
okay

54
00:05:17,079 --> 00:05:25,500
I know it's a mistake here

55
00:05:25,500 --> 00:05:27,540
because this is parasitizing

56
00:05:27,540 --> 00:05:28,639
and we have here

57
00:05:28,639 --> 00:05:29,459
commensalism

58
00:05:29,459 --> 00:05:30,139
okay

59
00:05:30,139 --> 00:05:31,199
because it said

60
00:05:31,199 --> 00:05:32,879
plus benefits the organism

61
00:05:32,879 --> 00:05:35,120
minus

62
00:05:35,120 --> 00:05:36,600
harms the organism

63
00:05:36,600 --> 00:05:37,600
zero

64
00:05:37,600 --> 00:05:38,560
doesn't affect

65
00:05:38,560 --> 00:05:39,759
so

66
00:05:39,759 --> 00:05:51,759
So, commensalism, remember, that is, one organism has a benefit, the other is a competition, yes?

67
00:05:55,759 --> 00:05:59,759
Competition, this is natural. Competition, what do you think?

68
00:05:59,759 --> 00:06:02,639
And the problem is when he's...

69
00:06:02,639 --> 00:06:03,019
Plus?

70
00:06:05,699 --> 00:06:06,620
And book.

71
00:06:06,819 --> 00:06:07,459
And hands.

72
00:06:08,720 --> 00:06:13,220
Well, I think one has benefits and the other not.

73
00:06:13,360 --> 00:06:13,720
Yes.

74
00:06:13,720 --> 00:06:14,939
Because they're competing for something.

75
00:06:15,100 --> 00:06:16,339
We'll have it and the other one.

76
00:06:16,699 --> 00:06:17,379
Mutualism.

77
00:06:17,980 --> 00:06:20,180
Mutualism.

78
00:06:20,779 --> 00:06:21,379
Mutualism.

79
00:06:21,379 --> 00:06:21,779
Yeah?

80
00:06:23,620 --> 00:06:24,560
Plus and plus.

81
00:06:25,779 --> 00:06:27,139
Yeah, but we're not sure.

82
00:06:27,339 --> 00:06:28,300
Plus and plus.

83
00:06:28,600 --> 00:06:29,300
Plus and plus.

84
00:06:29,300 --> 00:06:31,699
Because both are of benefit, right?

85
00:06:31,899 --> 00:06:32,139
Yes.

86
00:06:32,740 --> 00:06:33,899
Plus it dies and...

87
00:06:33,899 --> 00:06:34,939
Plus and rest.

88
00:06:38,300 --> 00:06:38,600
No?

89
00:06:39,160 --> 00:06:40,480
Plus and minus.

90
00:06:40,879 --> 00:06:41,180
Okay.

91
00:06:41,920 --> 00:06:42,540
Redition.

92
00:06:42,560 --> 00:06:43,639
And the last one, predation.

93
00:06:44,899 --> 00:06:46,319
Plus both.

94
00:06:46,319 --> 00:06:46,879
One.

95
00:06:47,540 --> 00:06:48,100
One.

96
00:06:48,259 --> 00:06:50,139
Take the benefit and you...

97
00:06:50,139 --> 00:06:53,339
Do you have good in it now?

98
00:06:53,639 --> 00:06:54,100
No.

99
00:06:56,100 --> 00:06:57,720
I have correct.

100
00:06:57,720 --> 00:06:59,579
so

101
00:06:59,579 --> 00:07:01,500
who wants this book?

102
00:07:02,120 --> 00:07:02,339
me

103
00:07:02,339 --> 00:07:04,519
mine

104
00:07:04,519 --> 00:07:15,939
thank you

105
00:07:15,939 --> 00:07:17,319
bye
