NEET BIOLOGY

Detailed explanation-1: -An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem.

Detailed explanation-2: -A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.

Detailed explanation-3: -Abiotic factors are physical and chemical elements within an ecosystem that are obtained from the lithosphere, hydrosphere, and atmosphere. Examples: air, sunlight, soil, air, nutrients in soil/water, oxygen, minerals, pH, etc. Man-made items are not abiotic because they do not exist naturally in an ecosystem.

Detailed explanation-4: -Dead organisms are not abiotic. Some people think that if an organism is no longer alive, it cannot be considered biotic. However, if something used to be alive, or was part of a living organism (such as a bone, or hair), it is still considered biotic.

Detailed explanation-5: -Abiotic factors are the non-living parts of the environment that have a major influence on living organisms. They can help determine things like how tall trees grow, where animals and plants are found, and why birds migrate. The most important abiotic factors include water, sunlight, oxygen, soil and temperature.
