Hey!Can somebody help me with this question please!
Why does a plant being fast growing & producing many light hairy seeds make it an efficient early coloniser in succession?
Is it because it can grow quickly ahead of competitors?And the thing about the seeds means it is wind dispersed but why does that make it efficient??? huh.gif

Pioneer species usually lichen, moss or algae, are the first species to occupy a new habitat, starting new communities. They have rapid reproductive strategies, enabling them to quickly occupy an uninhabited area. They can also withstand harsh environment conditions such as dessication.

As the seeds are light, they can be dispersed by wind. This is efficient as there is a higher chance of survival as the seeds are carried to new habitats to colonise.

Hope this helps!!
