Identify the oldest stage of succession shown in the figure above.
Would it be grassland or bare sand Beach?

Succession is the compositional and structural change of an ecosystem that occurs gradually with time.

The oldest stage of succession shown in the figure is: forest

The reason why the forest is the oldest stage of succession is as follows

When succession occurs in an area in which the existing ecosystem was

destroyed by a disturbance, it is known as secondary succession. Where

the succession is one that a barren land, or lifeless habitat is colonized by

plants and animals, it is known as primary succession

The oldest stage of succession, is the stage where there is stability, and

balance in the biomass, such that the number of species is relatively

constant, or the plateau region of the biomass time graph. It is the climax

stage or the final succession stage, where the development of the

community of organism has reached the maximum based on the

conditions of rainfall, light, and environmental conditions.

Therefore, given that the forest is the most developed stage of the community of organisms in the ecosystem, it is the oldest stage of succession in the ecosystem shown

Bare sand beach!

Explanation:

The grasses come slightly after pioneer species, like lichens and mosses that break down rock (or in this case sand) into soil. Since the sand is bare, you can assume no pioneer species have been there yet.

I hope this helps!
