Ecosystem and its Components Questions in English

(C) Ecosystems are primarily classified based on their habitat into two main categories: Terrestrial and Aquatic. However,in the context of standard biological classification,they are often grouped into three major types: $1$. Terrestrial (land-based),$2$. Aquatic (water-based),and $3$. Artificial (man-made). Therefore,based on the broad classification of habitat types,there are $3$ main types of ecosystems.

(C) Organisms that perform photosynthesis are known as $Producers$ (or $Autotrophs$).
They use sunlight, water, and carbon dioxide to synthesize organic compounds (glucose).
Since they produce their own food and serve as the primary source of energy for all other trophic levels in an ecosystem, they are called producers.
Examples include green plants, algae, and certain bacteria.

(A) In an ecosystem, energy flows from producers to consumers. According to the $10\%$ law of energy transfer, only about $10\%$ of the energy available at one trophic level is transferred to the next higher trophic level.
Since producers (plants) capture solar energy directly through photosynthesis, they possess the maximum amount of energy.
As we move up the food chain, energy is lost as heat during metabolic processes, resulting in a decrease in energy at each successive level.
Therefore, the producers occupy the first trophic level and have the highest energy.
