The term zonation refers to the distribution of marine organisms and the way they are organized into areas, populations, species, or higher level trophic levels. The zones can often be classified into broad groups such as zones of high productivity, zones with specific physiographic features, and zones that are influenced by specific environmental conditions.
What are the different stages of succession?
There are three different main stages of succession : the initial stage, the germination stage and the climax stage. In the initial stage, the seed germinates and eventually develops into a suitable environment. If all conditions of the habitat suit it, the seedling reaches maturity and produces a new shoot to develop a new plant.
Also Know, what is zonation and succession?
Zona – Zone – Zones. Zones are a series of rings around the globe formed by the Earth’s magnetic field and are generally divided into four regions: the polar summer Arctic (also called the polar winter Arctic), the tropics, temperate, and polar winter Arctic.
What is the difference between primary and secondary succession?
Secondary succession: a process that develops as a result of natural or man-made changes that create conditions favorable for new species to evolve; new communities come about when a landscape is converted by wind or water or by natural processes such as tree and/or plant growth in the soil. Primary succession refers to the change in plant and animal communities which occurs naturally on a virgin area of undeveloped land.
What are the horizontal zones of the ocean?
The World Ocean is divided into two large zones, the North Atlantic and the Southern Ocean. Between these is an intermediate zone known as the mid-oceans region (Figure 1). The main current and trade winds flow almost vertically through these zones.
What is the meaning of intertidal zone?
Intertidal Zone. The intertidal zone is a zone just above the tidal limit and extends from shoreline to land or beyond in the water, and is often also called the beach zone.
Why does zonation occur?
Zonation occurs during the first few weeks of germination. Zonation is a phenomenon in which a plant produces specific parts of the plant at specific growing points at specific elevations on the plant.
Considering this, what is species zonation in a community?
A simple rule for species zonation is that plants of different species are not found together. The result is that a community is zonated into zones of equal species composition with a dominant species in each zone.
What are the two major types of ecological succession?
Biological succession occurs gradually over many years and is often referred to as natural succession or simply growth. In contrast, biological succession results from the interaction between interacting players, or more specifically species. B. an organisms and their environment, and takes place much more quickly.
What is zonation in biology?
Zonation is usually referred to as the spatial arrangement in which different zones (suborganizations) are arranged in an organism at different locations and with specific functions.
What are the main physical characteristics of each intertidal zone?
On the shore, the zone extends to within a few hundred yards of the tidal base and ends at the mouth of the creek or bay, beyond which is the open ocean. At the mouth of a bay are the sand flats or beach and mud flats (or marsh).
What is a distribution pattern?
A pattern describes what kind of distribution occurs for two or more independent variables. For example, the pattern for the price of a computer is said to be linear or monotonic if it decreases with every additional unit (i.e., the price decreases as the quantity increases). Some patterns can be negative (i.e. the increase of the price with a decrease in the amount).
Why is the intertidal zone important?
The intertidal zone is critical to the marine ecology of the planet. Marine species and entire ecosystems that live at or near the ocean’s surface may depend on nutrients coming from the deeper benthic zone. These creatures rely on the intertidal zone as a natural source of food that protects them from predators and also provides them with shelter in hard-to-reach areas when the tide is low.
What causes primary succession?
Primary succession. Primary succession occurs as rocks and sediments (i.e., minerals and organic materials) become exposed to new environmental conditions. For example, a forest floor covered with leaf litter becomes exposed to light. Then, when the decomposition of these organic materials and the accumulation of soil begins, a forest floor develops.
What are the three main intertidal zones?
Habitats and their intertidal zones. The intertidal zone is the area between the low and high tides, a layer on each side of the shore. Intertidal areas include wetlands, dunes and scrubby shorelines.
What is the process of succession?
Succession means a continuation of a pattern of traits or behaviors as you age. This may result from one organism reproducing itself, or from one organism inheriting the traits of another.
What are the two types of intertidal zones?
There are two main intertidal zones: the low intertidal and the mid intertidal zone. The lower or lower intertidal zone consists of rocks or other terrain just below the tideline. They are the lowest area of the coast next to the shore at low water.
Why are vertical climate zones important?
Climate zones can be described according to the direction of the prevailing winds. A dry climate zone is a climate zone that is windy. The term “monsoon” was a common English term for a climate that is windy in summer and rainy in winter.
What does altitudinal zonation mean?
The altitudinal zonation of plants is the distribution of the altitude of the plant. The main altitudinal trends are the mountain altitude, valley, and plateau. The mountain area is defined as one area of land with a relatively low latitude and a relatively high altitude.
What animals live in the intertidal zone?
Birds. Fish. Sea crabs, starfish and others.
What is rocky shore zonation?
Rocky shore zonation and rocky shore species. A rocky, shaded habitat, usually at high points or islands, found on the shore, typically rocky, and in many cases shallow or exposed. These areas may be used for fishing (e.g. rockfish, salmon, eel and sea trout), forage (e.g. seals, marine birds) or as breeding grounds for seabirds and marine mammals.
In this way, what is the definition of vertical zonation?
Zone theory of vertical zonation. The physical, chemical, as well as the biological factors that influence the growth and distribution of terrestrial plants and forests.
