Hello students, in this question they have asked to select the plants which are the first ones to grow during primary succession.
00:11
Primary succession is the process of creating a new ecosystem from scratch.
00:27
This means that there is no soil, no nutrients, no plants, animals and no life has been existed before.
00:48
Therefore, the first organisms to grow in this environment are known as pioneer species.
01:14
These pioneer species are the first organisms to colonize a barren environment and they are usually small, hardy, unable to survive in harsh conditions and they are also able to break down rocks and other materials to create soil.
01:41
And once soil is created, other plants can grow and the ecosystem can become more complex.
01:48
Now let us look into the options given.
01:51
The first option given is trees.
01:53
This option is incorrect because trees require lot of nutrients and a stable environment to grow.
02:17
Therefore, trees cannot be the first organisms to survive.
02:25
The next option is ferns...
