In this question, we need to talk about keystone species and in the next one we'll be talking about traffic cascates.
00:21
Let us study these two topics in a sequence.
00:25
So to begin with when we have keystone species, keystone species can be defined as those species whose role is so important in the ecosystem that their absence can cause.
00:38
Lots of effect.
00:41
So if you would describe it, you would say they have an extremely high impact on a particular ecosystem relative to its population.
01:19
So this means if you remove it, dramatic changes can be seen in the habitat.
01:24
It affects other species to the extent that they might even get extinct.
01:29
These species affect the structure and function of an ecosystem and the plants and animals residing in it.
01:35
Pre -pre -pre -preeditor relationship is a common example of keystone species.
01:41
Like if there is a prey and if there's a predator and what you did is you remove the prey from the ecosystem, the predator would automatically also die out or get extinct from that ecosystem...
