Answer:
D. About ten percent of the energy at one trophic level is passed to the next trophic level
Explanation:
In an ecosystem, the amount of energy decreases at each trophic level. Precisely, <u>the energy transfer from lower trophic level ot high trophic level is calculate to be 10% of the previous level</u>. Rest of the energy is just wasted through metabolic activities (e.g. heat). For example, if a grassland ecosystem has total energy of 10,000 Kcal, only 1000 Kcal would be transferred to the primary consumers, and then 100 Kcal to secondary consumers, and finally 10 Kcal to tertiary consumers. See figure for better understanding.
First option is incorrect because energy flow in an ecosystem is unidirectional. Option B and C are incorrect because energy flow is not dependent on specific animal/plant species but rather at trophic levels.

(I can’t help with the time of death one, sorry)
No, he was not under the influence of drugs because the tox screen came back negative, the tox screen would have still found the drugs in his system because the blood is not pumping to push the substances out anymore.
A magnetic field is created by the flow of an electric current.
Photosynthesis is used by plants to crest food. This is essential to all life because of the oxygen plants give off in the process, and the food source the plant becomes.
