Surtsey is a volcanic island that was formed off the coast of iceland in the 1960s. After the eruption that created the island, organisms slowly arrived and grew on the island. The first organisms were some bacteria and fungi. Within about two years, the first vascular plants had arrived and by the end of the first decade there were 10 species of vascular plants on the island. Forty years later, there were about 60 species of vascular plants. What is likely true about this situation

The first organisms were some bacteria and fungi.

Explanation:

The first organisms were some bacteria and fungi on the Island of Surtsey because these bacteria and fungi are present in the surrounding air  which can easily reach to that Island. The bacteria and fungi make the environment favourable for the growth of plants and animals. These bacteria and fungi ready the ground for the plants so that they can grow easily with the passage of time.
