What is the difference between primary and secondary succession? Primary succession is a process by which a community arises in a virtually lifeless area with no soil. Secondary succession follows a disturbance that destroys a community without destroying the soil.

Primary coasts are formed by more land-driven rather than ocean-driven processes like plate tectonics, land erosion and sedimentation. Secondary coasts are formed by more ocean driven processes like wave erosion or growth of a coral reef.

Difference Between Germination and Emergence. The key difference between germination and emergence is that seed germination is the development of the seeds into new plants while emergence is the appearance of a seedling through the soil. ... A seedling that emerges from a seed can mature into a new plant.

Primary xylem is the xylem formed during primary growth from the procambium of the apical meristem. The secondary xylem is the xylem formed as a result of secondary growth from the vascular cambium of the lateral meristem. It is differentiated into two parts: Metaxylem and Protoxylem.

Succession is the process of ecosystem recovery after some disturbance. Biomass is at maximum in the undisturbed ecosystem; it increases up to this maximum during succession. Plant productivity also grows, especially if the plant cover was destroyed substantially by the disturbance.

Ecological succession is a series of progressive changes in the species that make up a community over time. Ecologists usually identify two types of succession, which differ in their starting points: In primary succession, newly exposed or newly formed rock is colonized by living things for the first time.

Xylem transports water and dissolved materials from the roots upwards. Phloem transports materials down from the leaves. Primary growth results in the increase in length of the primary plant body. Primary growth occurs at the apical meristem (a meristem located at the tip of a stem).

The primary market is where securities are created, while the secondary market is where those securities are traded by investors. In the primary market, companies sell new stocks and bonds to the public for the first time, such as with an initial public offering (IPO).

Difference Between Tap Root and Fibrous (Adventitious) Root. The main root (primary root) with other minor side roots, which grow deep into the soil is called Taproot. While the fine, thick hairs like structure, that spread sideways in all the directions is called Fibrous or Adventitious root.

Key Differences Between Primary and Secondary Data Primary data is a real-time data whereas secondary data is one which relates to the past. Primary data is collected for addressing the problem at hand while secondary data is collected for purposes other than the problem at hand.

There are two types of succession. The first is primary succession. ... The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.

The main difference between habitat change and habitat fragmentation is that the habitat change is the change in the local environmental conditions in which the organisms live whereas the habitat fragmentation is the loss of habitats by the division of large habitats.

The principal difference in primary and secondary treatment is the process that breaks down the sewage in wastewater. ... The initial and primary water treatment process removes large matter from wastewater while the secondary treatment will remove smaller particles already dissolved or suspended.

The Vascular Cambium and Secondary Growth. The vascular cambium and cork cambium are secondary meristems that are formed in stems and roots after the tissues of the primary plant body have differentiated. The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue.

Primary nutrients: are those nutrients required relatively in large quantities by the plants for their growth and development. ... Secondary nutrients: are those nutrients which are required by plants in moderate amounts.
