How much energy is passed from one trophic level to the next? Explain why.

Why does the energy pyramid exhibit large reductions in energy level as we move up through the trophic levels?

State the second law of thermodynamics and apply it to the energy transfer from a trophic level to the next higher trophic level in a food chain.

What are trophic levels?How many trophic levels can afood chain have?

a) Each trophic level, on average, will move 10% of the energy tied up in molecules to the next trophic level. How much of the energy from the sun is actually brought in to the first trophic level? b) When the producers convert energy and tie it up in the first trophic level, it is brought in as heat. True or false? c) Which of the following are true about ecosystems? Check all that apply. They contain both living and nonliving components.They contain both living and nonliving components. There is a transfer of energy through the system and some energy is lost as heat energy.There is a transfer of energy through the system and some energy is lost as heat energy. Nutrients repeatedly cycle through the ecosystem.Nutrients repeatedly cycle through the ecosystem. They represent the lowest level of biological organization.They represent the lowest level of biological organization. The ultimate source of energy for most ecosystems is organic molecules.

In the trophic structure, autotrophs are living organisms that:     Are at the top of the chain, referred to as tertiary producers.     Photosynthetic organisms that produce their own energy     Organisms that receive their energy by consuming producers such as plants     Help to decompose the remains of dead organisms

Give an account of energy flow in an ecosystem.

can someone please help me to answer questions a-b  thank you  1In a trophic pyramid, each level is smaller than the one below. a) What does the size of each level represent? b) How much energy is transferred from level to level? c) Explain why the levels get smaller as the trophic pyramid goes up.

In a terrestrial ecosystem such as forest, maximum energy is in which trophic level?

What is the primary sourcr of energy on earth?
