LIFE SCIENCE

Detailed explanation-1: -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-2: -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-3: -Examples of abiotic factors include sunlight, water, air, humidity, pH, temperature, salinity, precipitation, altitude, type of soil, minerals, wind, dissolved oxygen, mineral nutrients present in the soil, air and water, etc.

Detailed explanation-4: -Autotrophs – produce their own food by using sunlight by the process of photosynthesis. Example plants, green algae. Heterotrophs – these organisms depends on producers for their food. Example – humans. Decomposers – consume, decompose dead and decaying matter.
