An ecosystem (or ecological system) is a system that environments and their organisms form through their interaction.: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.
A lake ecosystem or lacustrine ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (non-living) physical and chemical interactions. Lake ecosystems are a prime example of lentic ecosystems (lentic refers to stationary or relatively still freshwater, from the Latin lentus, which means "sluggish"), which include ponds, lakes and wetlands, and much of this ...
Ecosystem ecology is the integrated study of living ( biotic) and non-living ( abiotic) 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 ecology examines physical and ...
Environmental factor. An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. [1] Abiotic factors include ambient temperature, amount of sunlight, air, soil, water and pH of the water soil in which an organism lives. Biotic factors would include the availability of food ...
Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment . Ecosystem diversity addresses the combined characteristics of biotic properties ( biodiversity) and abiotic properties ( geodiversity ). It is a variation in the ecosystems found in a region ...
An ecosystem is composed of biotic communities that are structured by biological interactions and abiotic environmental factors. Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.
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.
Competition (biology) Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory ). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other.
