An ecosystem is a biological environment consisting of all the organisms living in a particular area, as well as all the nonliving (abiotic), physical components of the environment with which the organisms interact, such as air, soil, water and sunlight. Ecosystems are functional units consisting of living things in a given area, non-living ...
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.
Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production , nutrient cycling , and niche construction , regulate the flux of energy and matter through an environment.
An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.
Ecosystem ecology is the integrated study of living and non-living components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals , bedrock , soil , plants , and animals .
Ecosystem – Community of living organisms together with the nonliving components of their environment, or Biome – Biogeographical unit with a particular biological community Community (ecology) – Associated populations of species in a given area, or Biocoenosis – Interacting organisms living together in a habitat
The feeding relationships between different species in a given ecosystem. Also called a food chain, food network, or trophic social network. weed A plant growing where it is not wanted, often at a high rate of dispersal. wetland A type of ecosystem consisting of land permanently or seasonally saturated with water; the habitat of aquatic plants ...
Lentic ecosystems can be compared with lotic ecosystems, which involve flowing terrestrial waters such as rivers and streams. Together, these two ecosystems are examples of freshwater ecosystems. Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1642 m. [2]
