Answer:

It can

be explained with the help of ten percent law which

states that only 10 percent of the total energy available

at any trophic level is passed on the higher trophic level .

Most of the energy is lost as heat or is used in the

process of cellular respiration.

The percent of energy is transferred from the sun to the level indicated is 10 percent .Therefore , 10 percent is correct .

Only a small fraction of the Sun's energy is harnessed and transferred through various levels in ecosystems.

The process of energy transfer follows the laws of thermodynamics and is typically illustrated in ecological pyramids.

The first trophic level, occupied by primary producers like plants and algae, captures sunlight through photosynthesis, converting it into chemical energy.

However, approximately 90% of the energy is lost during each transfer between trophic levels.

This loss occurs due to metabolic processes, heat production, and incomplete consumption of organisms at each level.

As energy moves from producers to herbivores (primary consumers) and then to carnivores (secondary consumers) in the food chain, a significant portion is expended as metabolic heat or used in sustaining life processes.

This phenomenon is often represented in ecological pyramids, visually depicting the diminishing energy available at higher trophic levels.

The 10% energy transfer efficiency is a general rule of thumb, with variations depending on ecosystem dynamics and environmental conditions.

This limitation underscores the importance of maintaining diverse and balanced ecosystems, as excessive disruptions to trophic structures can have cascading effects on energy flow and ecosystem stability.

Energy transfer in ecosystems is crucial for addressing ecological issues, conservation efforts, and sustainable resource management.

It highlights the interconnectedness of species and ecosystems and emphasizes the delicate balance required for the efficient functioning of ecological systems.
