Answer:

(Wow! Weird how this pooped up, I just finished this biology lesson.)

Explain the 1st and 2nd law of thermodynamics in terms of food chain, energy flow, pyramid of number and pyramid of energy
Westkost [7]

Answer:

First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.

Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.

In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).
