factors affecting the distribution and abundance of behaviour in plant and animal

Light affects the distribution of animals by affecting the vegetation. For example Tundra biome is characterized by insufficient light, low temperature, less vegetation so less animal life. While tropical area is characterized by high rainfall, str..

Plant growth is influenced by a number of external and internal factors. The external factors affecting plant growth are: i) light ii) temperature iii) oxygen iv) carbon dioxide v) soil water vi) soil nutrients The internal factors af..

Anatomy which favours the amount of CO 2 diffusion into collenchyma cells the intensity dilution of light and the rate of photosynthesis. Thickness of epidermis, size structure, position and frequency of stomata, distribution of vascular tissue and intercellular spaces, position an..

Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis is limited by the most limiting facto..

Light - The effect of light on growth can be studied under 3 headings light intensity, light quality and duration of light. Growth is generally favoured by darkness, but light is indispensable because of its role in the manufacture of food. Young plants growing in the absence of light dev..

Rainfall is a source for ground water and relative humidity. The amount of rainfall greatly affects the vegetation as well as animal population of a particular region. In tropical areas with heavy rainfall throughout the year, vegetation mainly include evergreen forests and ..

. The large-sized varieties of the species were also found there. For example, he found the giant tortoise attained a huge size of 2m length and 260kg weight. The iguana lizards were also larger and more abundant than the land species. There were 13 species of finches as opposed to only o..

Climatic Factors - Wind - Air in motion is called wind. Wind velocity can be measured by an Anemometer. It is an important ecological factor of the atmosphere affecting variously the plant life on flat plains, along sea coasts and at high altitudes in mountai..
