define abiotic and biotic?
Answers
Answer:
Biotic Factors Definition
The biotic factor or biotic component is
the living organism that shapes an ecosystem.
•Biotic factors include plants, animals, bacteria, algae, and all other living forms present in an ecosystem.
•An ecosystem is a complex system of living and non-living things; the living part of the system forms the biotic factors.
•Biotic factors include all producers, consumers, and decomposers that are involved in the transformation and transport of energy through the food cycle.
•These biotic factors are also responsible for diseases and outbreaks.
•Producers are the group of organisms that make up their own food through processes like photosynthesis.
•Most producers use photosynthesis to convert solar energy to chemical energy, but various autotrophs also utilize other processes like phototrophy and chemotrophy.
•All green plants contain chlorophyll as the photosynthetic pigment for the process of photosynthesis. Other pigments like bacterial rhodopsin and carotenoids are also found in some bacteria, algae, and phytoplankton for photosynthesis.
•Some producers generate food by the process of chemosynthesis, which derives the energy from chemical reactions, rather than sunlight.
•Consumers are the groups of organisms that feed on producers, directly or indirectly, for energy and food.
•Consumers reside in separate trophic levels, as primary and secondary consumers. Primary consumers are herbivores that directly dependent on autotrophs or producers. Secondary consumers, in turn, feed on primary consumers.
•Biotic factors of the ecosystem are responsible for capturing the energy for the conversion of inorganic compounds into organic compounds.
Biotic factors, with abiotic factors, determine the nature of the ecosystem and ecological niches.
Abiotic Factors Definition
The abiotic factors or abiotic components of an ecosystem are the non-living
physical and chemical composition of nature.
•Abiotic factors include factors like sunlight, water resource, air, soil, rocks, tides, temperature, rain, and humidity, among others.
•These factors affect the growth, survival, and reproduction of living organisms and their functioning in the ecosystem.
•All the environment resources are either utilized by different living organisms or made unavailable to organisms after being utilized by other organisms.
•Natural degradation of various components like chemicals or rocks occurs via hydrolysis or other physical processes.
•Abiotic factors are composed of all non-living organisms, like atmospheric conditions and water resources.
•The abiotic component of an ecosystem also defers on the basis of the type of ecosystem. Sand plays an essential role as an abiotic factor in the desert ecosystem, whereas rainfall is an abiotic component in the tropical forest ecosystem.
•Pressure and sound waves are the abiotic components in the marine ecosystem along with other factors like water clarity, aerial exposure, and water tides.
•Biotic factors of different ecosystems adapt to the abiotic factors of that particular ecosystem. One example of this is the archaea found in extreme environments that utilize the biotic factors for their survival and growth.
•The abiotic factors also affect eh living organisms of the ecosystems. Depending on the ability of the organisms, only the organisms capable of withstanding these abiotic factors will survive in such ecosystems.
•Sometime, these factors might even evolve the nature of different ecosystems. Lack of rainfall might convert a tropical ecosystem into the desert ecosystem.
Explanation:
Hope it will help.
it's quite long but it's important.
In biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin biology as a whole
