Answer: B). Primary succession takes place over a long period of time on a newly formed land, while secondary succession occurs quickly in areas that have disrupted by a natural disaster.
Explanation:
A succession is a gradual change that occur within the biotic community due to change in the non-living environmental factors with respect to time until the community establish stability.
A primary succession occurs over a land which was not previously occupied by any living species. The land can be primitive, environmental factors like soil, air and others are not supportive initially. Thus, it takes long time to establish a biotic community.
A secondary succession occurs over a region which was previously inhabitated by colonies of species but disturbed due to natural calamity or human induced disaster. Some of the precursors of life can be found in such region like seeds, spores, roots and others which support new growth and the environmental factors are suitable to support re-establishment of living species. Hence, secondary succession takes place quickly as compared to primary succession.
Answer:
multipennate; triangular
Explanation:
The deltoid is referred to as the muscle that plays an important role in the ability for the arm to be lifted and also the movement of the shoulder. It is found at the upper part of the shoulder and arm. The fascicle of the deltoid which is represent bundle of fibers of the muscle is multipennate, meaning it is has several tendons arranged at several angles.
