Practice: Community structure and diversity. A mature community has greater diversity, larger organic structure, and balanced energy flows. Typically, the first species that recolonize a site after a fire are pioneer herbaceous species, such as fast-growing grasses and weeds. These pioneer species gradually spread into and through the barren landscape preparing it for larger more complex organisms. Man must have early successional stages as a source of food, since he must have a large net primary production to harvest. Community structure and diversity. Often secondary succession occurs in a single century or less. The animals found during this stage include nematodes, insects larvae, ants, spiders, mites, etc. Primary Succession: Primary succession is the establishment of plants on land that has not been previously vegetated. It is a predictable change and is an inevitable process of nature as all the biotic components have to keep up with the changes in our environment.. The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The intricate problems of competition between different species of animals can be studied in series of changing communities. Thus, it becomes clear that succession has a very significant role in shaping the destiny of animal and plant communities.However, succession is not always predictable and unidirectional. A favourable situation exists in many terrestrial landscapes where productive croplands on the plains are intermingled with diverse forests and orchards on the hills and mountains. They make the area suitable for the growth of larger species such as grasses, shrubs and finally trees.Small coral polyps colonize the rocks.

Ecological succession is a process in which diverse biological communities develop over time. They are often perennial species that spread quickly, die off each season and leave behind a large amount of seeds for the next season. Ecological succession is a term developed by botanists to describe the change in structure of a community of different species, or ecosystem.The concept of ecological succession arose from a desire to understand how large and complex ecosystems like forests can exist in places known to be recently formed, such as volcanic islands. In an attempt to reach this equilibrium, some species increase in number while some other decreases.Ecological succession is important for the growth and development of an ecosystem. If the forests are destroyed merely for the temporary gain of wood, water and soil may wash down from the slopes and reduce the productivity of plains.Welcome to BiologyDiscussion!
