hierarchy level of organisation ?

Every organism consists of parts that can be arranged in increasing levels of complexity. Each higher level is more complex than the one below it. The smallest structural unit of matter, both non-living and living are protons, neutrons and electrons. These particles combine in a..

Living Beings are Organised - Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common..

Different types of tissue may together become organised into an organ for some specific function. E.g., a gland is an organ meant for secretion. In a gland there are four tissues - Epithelium (for secretion) Muscular tissue (for contraction of the gland) Connective tissue (for bi..

One of the main characteristics used in defining grades of animal complexity is the presence or absence of tissues. Tissues are the aggregations of embryologically and morphologically similar cells that become arranged to perform specific functions. The protozoans occur as single cells or colonies ..

An organism is a distinct unit of life in nature. It is said to be the smallest level and basic unit of ecological hierarchy..

Both living organisms and non-living matter are composed of some basic elements and are bound by the same physical laws. However, living organisms differ from non-living matter in some specific aspects. Living organisms exhibit a kind of organisation from molecular level to..

It is a highly organised, integrated and complex society, which involves the division of labour at the individual level. This high level degree of division of labour is due to well-developed instinctive behaviou..

Population and Its Characteristics - Population is the next level in ecological hierarchy the word population has its origin in the Latin word populus meaning 'people'. In ecology, population is defined as the total number of all individuals of a particular species, which breed ..
