Question

Visit an ecosystem nearby. List the biotic and abiotic factors in it. Show with pictures and sketches, how they are dependent on each other.

Answer 1

Hint: An ecosystem is a geographical area in which plants, animals, and other species, as well as weather and topography, interact to generate a living bubble. Ecosystems comprise both biotic and abiotic elements, or living and nonliving components. Plants, animals, and other species are examples of biotic factors. Ecosystem functions are natural processes or energy exchanges that occur in various plant and animal groups throughout the world's biomes.

Complete answer:
Part (i) All living organisms in the ecosystem are affected by biotic forces. Their existence, as well as their biological by-products, have an impact on ecosystem composition. All living species, from animals and people to plants, fungi, and germs, are considered biotic factors. Interactions between diverse biotic variables are required for each species' reproduction and to meet basic needs such as food.
All of the living components in an ecosystem are examples of biotic resources. Producers, consumers, decomposers, and detritivores are among them.
Part (ii) All non-living, chemical, and physical factors found in the atmosphere, hydrosphere, and lithosphere are referred to as abiotic factors. Abiotic variables include things like sunlight, air, precipitation, minerals, and soil. These variables have a big impact on a species' survival and reproduction in an ecosystem. A terrestrial ecosystem's abiotic components include air, weather, water, temperature, humidity, altitude, soil pH, kind of soil, and more. Water salinity, oxygen levels, pH levels, water flow rate, and water temperature are all biotic examples in an aquatic ecosystem.

Note:
An ecological pyramid is a graphical representation of the link between diverse living beings at various trophic levels within a food chain. The pyramid is built on the basis of the number of organisms, energy, and biomass, and it is shaped like a pyramid, as the name suggests. Number, Biomass, and Energy are the three types of ecological pyramids. A graphical representation of the connections between different organisms in an ecosystem is called an ecological pyramid. It depicts the flow of energy in an ecosystem at various trophic levels.
