Question

What happens in the sequence: Moss lichen and micro organisms occur, grass grows, weeds and larger plants invade, shrubs grow, trees become dominant?

1) Moss lichen and micro organisms occur, grass grows
2) Grass grows, shrubs grow
3) Weeds and larger plants invade, shrubs grow
4) Trees become dominant

Answer 1

The sequence of events in the ecosystem involves the colonization of bare land by pioneer species, followed by the growth of grass, invasion by weeds and larger plants, the growth of shrubs, and finally, the dominance of trees.

Step-by-step explanation:

The sequence of events in the ecosystem can be summarized as follows:

1. Moss lichen and microorganisms occur, grass grows: Moss lichen and microorganisms are the pioneer species that colonize bare land. Grass is able to grow in the newly developed soil.
2. Weeds and larger plants invade, shrubs grow: As the grass grows, it provides favorable conditions for weeds and larger plants to invade the area. Shrubs also start growing at this stage.
3. Trees become dominant: Over time, the shrubs are replaced by small trees. These small trees eventually give way to larger trees, which become dominant in the ecosystem.
