Energy Flow in Ecosystem

The video explains energy's role in ecosystems, focusing on solar energy and its conversion through photosynthesis. It covers the unidirectional flow of energy, governed by thermodynamics laws, and the inefficiency of energy transformations. The video describes food chains, trophic levels, and the interconnectedness of food webs. It distinguishes between grazing and detritus food chains, highlighting their roles in different ecosystems. The concept of standing crop and the 10% law of energy transfer across trophic levels are also discussed.

What role do autotrophs play in the energy flow of an ecosystem?

What are the differences between a grazing food chain and a detritus food chain?

How does energy transfer between trophic levels, and what is the 10% law?
