What is the biotic factor in a terrestrial habitat?
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.

Ecological Factors Influencing Terrestrial Plants And ... - UKEssays
Ecology was first defined by Ernst Haeckel in 1866 as “the science of relations between organisms and their environment (Bramwell 1989). The study of ecology has developed over the years from an initial descriptive field of study in the 19th century to a more quantitative, experimental and analytical discipline in the 21st century (Mayorga et al. 2002).

Definition of terrestrial habitat
The terrestrial habitat is the place where different species of plants and animals live on the earth’s surface (geosphere) . The main characteristic of these habitats is the presence of oxygen in the atmosphere and the possibility of sudden changes in temperature and other meteorological phenomena.
Terrestrial habitat types – examples
In each region of the world, the types of terrestrial habitats that we can find present diverse climatological, environmental and geographical characteristics that allow us to differentiate them from each other. To get to know them more closely, let’s put some examples of the different types of terrestrial habitats :
Terrestrial habitat animals
All animals in the terrestrial habitat are characterized by the need to obtain oxygen for respiration, which is carried out through the lungs. Their diet is based on the acquisition of plants or other animals.
Ecological Factors Affecting Terrestrial Habitats
Topographic Factors: These factors are associated with the structure of the habitats e.g. effects of hilts, valleys, plains mountains and rivers. These factors bring about variation in the vegetation and types of animals in an area.
Ecological Factors That Affect Aquatic Habitats
Salinity: This refers to the concentration of salts in the water. Salinity affects the movement of water and salts across the body tissues of aquatic organisms. Salinity is low in fresh water, high in sea water and moderate in brackish water.
Ecological Factors Common To All Habitats
The ecological factors that affect both the terrestrial and aquatic habitats are mainly climatic e.g. temperature, rainfall, relative humidity, wind, high intensity hydrogen ion concentration (pH) and pressure. Of these factors temperature and rainfall determine the type of vegetation in a region.
Biotic Factors Affecting the Ecosystem
Biotic factors refer to the effects of plants and animals on themselves or one another. The biotic factors include:
What is the terrestrial environment?
The terrestrial environment covers the soil and soil/air interface and the associated biological communities. Most living organisms are directly associated to the interface between the soil and the above soil compartment, being simultaneously and/or alternatively in contact with both compartments.
Which environment has the most diversity of trace fossils?
Terrestrial environments experienced an increase in diversity of trace fossils, particularly in eolian deposits, where the ichnofauna displays more varied behavioral patterns than their Paleozoic counterparts (Gradzinski and Uchman, 1994).
What is an extreme environment for algae?
An extreme environment for algae is the surface of more or less permanent snowfields. The only filamentous green alga among other forms associated with this inhospitable environment is Raphidonema ( Hoham, 1973 ). Often snow banks containing large quantities of algae are streaked green, yellow, or reddish depending on the dominant alga and the extent to which the green chlorophylls are masked by the red carotenoid pigments (see also Chapter 2; Section VI—B).
What is the environment of caves?
The terrestrial environment in long caves is buffered from climatic events occurring outside. The temperature stays nearly constant, usually near the mean annual surface temperature (MAST); except passages sloping down from an entrance tend to trap cold air and remain a few degrees cooler than MAST. Passages sloping up are often warmer than MAST. The environment is strongly zonal (Fig. 1 ). Three zones are obvious: an entrance zone where the surface and underground habitats overlap; a twilight zone between the limit of photosynthesis and total darkness; and the dark zone. The dark zone can be further subdivided into three distinct zones: a transition zone where climatic events on the surface still affect the atmosphere, especially relative humidity (RH); a deep zone where the RH remains constant at 100%; and an innermost stagnant air zone where air exchange is too slow to flush the buildup of carbon dioxide and other decomposition gasses. The boundary between each zone is often determined by shape or constrictions in the passage. In many caves, the boundaries are dynamic and change with the seasons.
What is the water loss of terrestrial animals?
Evaporative water loss (EWL) across the skin and respiratory tract is a major avenue of water loss by terrestrial animals. Water is also lost in feces and urine. Water is gained in a terrestrial environment via drinking, as preformed water in food, and as metabolic water production. Water may also be absorbed across the body surface.
Where do rhizosphere organisms live?
In contrast, rhizosphere organisms reside in soil adjacent to, and under the influence of, plant roots. In both cases, the microbes receive plant metabolites or exudates as a source of nutrition. In return, many of the microbes, especially the endophytes, provide metabolites that protect the plants.
Is terrestrial or freshwater harsher?
The terrestrial environment is harsher than marine or freshwater environments. Shortage of water, ultraviolet radiation, rapidly fluctuating temperatures, and a number of obstacles against movement and/or the dissemination of offspring create survival problems, but also opportunities for evolution and speciation.
How does water current affect the distribution of aquatic organisms?
It also affects the distribution of aquatic organisms. The type of organism found in an aquatic habitat is affected by the speed of current. For example, animals living in fast moving waters have structure that enables them to attach themselves to rock surfaces to avoid being swept away
How do waves affect aquatic organisms?
Some may possess hard body cover to prevent evaporation of water from their body. In the open sea, wave cause the aeration of the surface water , enabling aquatic organisms to have sufficient supply of dissolved gases for their respiration
What causes turgidity in water?
Turgidity is also influence by season. Turgidity is higher in the rainy season. Turgidity reduces light penetration into water, resulting in the inability of aquatic green plants to carry out photosynthesis. Turgidity also causes pollution
What is the density of fresh water?
density of water varies the type of aquatic habitat. While the density of pure fresh water is 1.00, that of sea water is 1.028 at atmospheric pressure and at 0C. organisms like fishes have streamlined bodies which enable them to move through water easily while other organisms which float on the surface of the water are sensitive to changes in density#N#6.
What are the factors that affect the terrestrial ecosystem?
Factors affecting terrestrial ecosystem are- (a) Moisture Water is important for growth of the plant because the nutrients required for the growth are supplied in a dissolved state from the roots to the leaves through the medium of water. Water, not only helps in the process of photosynthesis, but, also in germination, ...
What is the ecosystem that prevails on land called?
ADVERTISEMENTS: Ecosystem which prevails on land is called terrestrial ecosystem. Man is closely related to it as it provides us with our basic needs like food, shelter, clothing, etc. The surface of the land has a cover of diverse vegetation which depends on climatic conditions.
What type of soil supports vegetation?
Different types of soil, such as, alluvial soil, black soil, red soil, loamy soil, literate soil and sandy soil, all support different types of vegetation. For example, black soil is good for the cultivation of cotton. (d) Relief and (e) Drainage are other factors determining the type of vegetation. In mountains vegetation varies with altitude.
Why do plants not grow in the desert?
In deserts, plants do not grow for the greater part of the year, due to excessive heat and scanty moisture. Variation in temperature and moisture reduces variations in species also.
