An ecosystem (also called an environment) is a natural unit consisting of all plants, animals, and micro-organisms (biotic factors) in an area functioning together with all of the non-living physical factors of the environment. [34]
For example, the leaves of ferns and umbellifers (Apiaceae) are only self-similar (pinnate) to 2, 3 or 4 levels. Fern-like growth patterns occur in plants and in animals including bryozoa, corals, hydrozoa like the air fern, Sertularia argentea, and in non-living things, notably electrical discharges.
An example of a non-renewable natural resource. Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest, and cultural value.
Ecology (from Ancient Greek οἶκος (oîkos) 'house' and -λογία 'study of') is the natural science of the relationships among living organisms and their environment. Ecology considers organisms at the individual, population , community , ecosystem , and biosphere levels.
Conservation is the management of natural resources with the goal of sustainability. Natural resources may be further classified in different ways. [1] Resources can be categorized based on origin: Abiotic resources comprise non-living things (e.g., land, water, air, and minerals such as gold, iron, copper, silver).
Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms.
Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. Plants allow energy to enter the system through photosynthesis, building up plant tissue.
Habitat can be defined as the natural environment of an organism, the type of place in which it is natural for it to live and grow. [ 4 ] [ 5 ] It is similar in meaning to a biotope ; an area of uniform environmental conditions associated with a particular community of plants and animals.
