Biotic Component of Ecosystem

Biotic components of an ecosystem comprises of any living components that comes in contact with each other, their interaction and mutual influence. The biotic factors in an ecosystem include animals that consume other organisms and these organisms in turn are consumed by other organism in the higher trophic level. Biotic component comprises of the living part of the ecosystem; it includes the association of a number of interrelated populations that belong to different species. The living components of the ecosystem are the animals, plants and the microbes.

Biotic Components consist basically of the following:

Producers
Producers are organisms like the green plants which manufacture their own food in the form of organic nutrients from inorganic substances abiotic substances. Green plants produce food by the process of photosynthesis, the sun provides energy - this solar energy is converted into chemical energy in the green part of the plant - the chloroplasts. The chloroplasts contain the green pigment chlorophyll which traps energy from the sun for the process of photosynthesis. Producers are also known as autotrophs. Autotrophs are the basic of any biotic factor in an ecosystem. In a terrestrial ecosystem the producers or autotrophs are rooted green plants; on aquatic ecosystem, producers or autotrophs are floating plants called phytoplankton and shallow water rooted plants known as macrophytes.

Consumers
Consumers are the organisms that cannot make their own food from inorganic compounds. The consumers are dependent on autotrophic organisms or producers or other primary consumer or heterotrophic organisms in an ecosystem. The consumers are subdivided into herbivores, carnivores and omnivores according to their diet. In the trophic level they are known as primary consumers, secondary consumers and tertiary consumers.
  • Herbivores are organisms that feed on plants. They are known as primary consumers. Example: Cows, giraffes, elephants, etc.
  • Carnivores are animals that feed on herbivores and are meat eater. They are known as secondary consumers. Example: Crow, snakes, etc.
  • Tertiary consumers are animals that feed on secondary consumers and in turn are not preyed upon by any other organism. Example: Lion, tiger, etc.
  • Omnivores are organisms that feed both on plants and on animal matter, these organisms may be primary, secondary and tertiary consumers simultaneously. Example: Human being.
Decomposers
Decomposers are usually saprophytes. These are saprophytic organisms like bacteria and fungi that obtain their nutrition by decomposing dead matter of other organisms. These organisms break down the organic matter of the producers and consumers into inorganic material that are released into the soil or water which are then reused by the producers.

Biotic component

Biotic components are the living things that shape an ecosystem. A biotic factor is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes. Biotic factors include human influence.

Biotic components are contrasted to abiotic components, which are non-living components of an organism's environment, such as temperature, light, moisture, air currents, etc.

Biotic components usually include:

  • Producers, i.e. autotrophs: e.g. plants; they convert the energy (from the sun, or other sources such as hydrothermal vents) into food.
  • Consumers, i.e. heterotrophs: e.g. animals; they depend upon producers for food.
  • Decomposers, i.e. detritivores: e.g. fungi and bacteria; they break down chemicals from producers and consumers into simpler form which can be reused.

Question:

Answers:Abiotic: Water, Air, Nutrients, Rocks, Heat, Solar energy Biotic: Anything living or once living

Question:

Answers:The biotic components of the ecosystem can be categorized as either producers or consumers. Producers are autotrophic organisms with the capability of carrying out photosynthesis and making food themselves, and indirectly for the other organisms as well. In terrestrial ecosystems the producers are predominantly green plants, while in freshwater and marine ecosystems the dominant producers are various species of algae. Consumers are heterotrophic organisms that used food that has already been performed by other organisms. It is possible to distinguish four types of consumers, depending on their food source. The abiotic components include soil, water, light, inorganic nutrients and weather.

Question:a. abiotic are non-living (rocks) and biotic are living (plants) b. Abiotic are living (plants) and biotic are non-living (rocks) c. Abiotic products make up the entire ecosystem. d. Biotic products make up the entire ecosystem

Answers:A. abiotic are non-living (rocks) and biotic are living (plants) B is false since the definition of abiotic is nonliving and the definition of biotic is living. C is false since animals and plants which are living also make up an ecosystem. D is false since nonliving things like temperature, soil, and rocks also make up the ecosystem.

Question:

Answers:Biotic is living and Abiotic is non-living.
