Properties of Population Ecology

Properties of Population Properties of population ecology Populations have many unique features. They have an ago structure, density, and distribution in time and space. They exhibit a birth rate, a death rate (mortality), and a growth rate. They respond in their own ways to competition, to predation, and to other pressures. Individuals make up a population affect one another in various ...

The Study of Interaction Between Organisms and their Environment

Organisms and Their Environment

Organisms and their Environment Organisms and their Environment – All organisms live in a varying physical environment of temperature, moisture, light and nutrients. These factors differ from location to location like in latitude, region and locality. In addition, at any location, the physical environment varies with time to time, yearly seasonally and daily. One important example of environmental variation is ...

How Does Wind Affect Plants

Wind Affect on Plants Air in motion is called wind. Wind affect plants directly by increasing transpiration, by delivering heat to relatively cool leaves or dissipating the heat load of isolated leaves, by causing various kinds of mechanical damage and by scattering pollen’s and dispersal of seeds and fruits. Wind plays important role as an ecological factor especially on flat plains, along seacoasts ...

Adaptation of Plants to Temperature

Adaptation of Plants to Temperature

Physiological Responses and Adaptations of Plant to Temperature The adaptation of plants to temperature have greatly succeeded in development with the passage of time. They have developed a number of morphological and physiological characteristics during the course of evolution in order to meet extremes of temperature conditions. Formation of dormant bulbs, tubers; leaf fall and associated dormancy during winter or dry season ...

Drought Resistance Mechanism in Plants

Drought Resistance Mechanism Drought can be defined as an extreme fluctuation from the rainfall (usually than 75% of the normal) at a certain place in a particular area. In water stress areas the plants (xerophytes and succulents) are adapted to shortage of water and dry season normally does not affect their growth. However, if the rainfall drops far enough below ...

Hydrologic Cycle Steps

Water exhibits cyclic flow between atmosphere, land and sea, and between living organisms and their environment. This is referred to as Hydrologic cycle or water cycle. Without cycling of water nutrients could not flow through the ecosystem, ecosystem could not function and life could not be maintained. Hydrologic Cycle Steps Water cycle is characterized by precipitation, interception, infiltration, and evaporation. ...

Ecophysiological Responses of Plants to Light

Ecophysiological responses of plants to light are photosynthesis, transpiration, seed germination, photoperiodism, reproduction and growth, and ecological classification. Ecophysiological Responses of Plants to Light The ecophysiological responses of light which affects plants in various ways are as follow: Photosynthesis The plant shoots are adapted to receive and absorb sunlight. Most leaves get saturated with only about 20% of full sunlight. ...

Temporal and Spatial Variations in Intensity of Light

Light varies in intensity, (i.e., temporal and spatial variations) duration and quality (proportions of red, yellow, blue, etc.) These variations are important in plant ecology; however, the intensity and duration of light is more important since it difficult to interpret the effect of quality of light for practical reasons. Temporal and Spatial Variations in Light Intensity The intensity of light exhibits spatial ...

Role of Light in Ecology

Role of light is an important role in this world. As Light factor is the most essential abiotic factor without the life cannot exist. The chief natural source of light is sunlight and has great ecological significance. It plays important roles in the life of plants, such as It provides energy to maintain life on earth. It is absorbed to ...
