a grassland ecosystem contains grasses, rabbits, snakes, and hawks. using the laws of thermodynamics, what prediction can be made about the energy transfer through this food chain? energy is not lost in the food chain, it cycles completely back to the grass. rabbits will receive the same amount of energy from the grass as the grass gained from sunlight. only a small portion of the grasses energy will be available to the rabbits, and even less will transfer to the snakes and hawks. all the energy from the grass will be passed to the rabbits, and the same amount of energy will be transferred to the hawks.

Answer

Explanation:

Step1: Recall 1st law of thermodynamics

Energy is conserved but can change forms.

Step2: Recall 2nd law of thermodynamics

In energy transfer, some is lost as heat. In a food - chain, producers (grasses) convert solar energy to chemical energy. Consumers (rabbits, snakes, hawks) get energy by eating other organisms.

Step3: Analyze energy transfer efficiency

Energy transfer between trophic levels is inefficient. Typically, only about 10 - 20% of the energy from one trophic level is passed on to the next. So, only a small portion of the grasses' energy will be available to the rabbits, and even less will transfer to the snakes and hawks.

Answer:

Only a small portion of the grasses' energy will be available to the rabbits, and even less will transfer to the snakes and hawks.
