Any change in plant communities over time is called a(n) . 2. A common pioneer organism in a succession is the .
In biology, the term 'succession' is used to refer to the natural changes that occur in plant communities over time, often after a significant environmental disturbance. These changes happen in predictable order, beginning with 'pioneer species' (usually grasses and plants), followed by 'intermediate species' (smaller trees), and finally culminating into the 'climax community' where the forest resembles the pre-fire state.
Any change in plant communities over time is known as succession. This concept describes the sequential appearance and disappearance of species within a community. For instance, following a calamitous event such as a forest fire, the first plants to re-emerge are known as pioneer species which are essentially annual plants and grasses. As time progresses, environmental conditions change, and types of vegetation, such as small pine, oak, and hickory trees known as intermediate species appear. Ultimately, after a century or two, the forest will regain equilibrium and look the same as before the fire in a state known as the climax community. The process of attaining this stage in a community may also be triggered by short and long-term changes in the environment.
