Here we're going to talk about relationships between organisms.
00:19
And there are five main types of relationships.
00:24
The first one is going to be a predation, also known as a predator prey.
00:38
And for this particular relationship, we look at those two organisms and how they interact with each other.
00:48
So in this case, the predator would be happy because they're getting food.
00:54
And the prey would be sad because they are getting eaten.
01:01
Our next relationship is competition.
01:11
And in the ecosystem, organisms of different species are going to be competing for limited resources.
01:28
And a limited resource in most ecosystems, for example, would be space.
01:39
The third type of relationship that you could see is parasitism.
01:51
And because parasites need a host, you have your parasite and your host.
02:00
And for this one, the parasite would be happy because it's going to be.
02:06
Getting food from the host, but the host would be sad because in this situation, the host is harmed and most often is killed.
02:20
Our next relationship is going to be mutualism...
