If grass stores 1,000 energy units received from the sun, the ecological efficiency of the ecosystem is 10%, and the trophic levels are grass → cow → human, how many units of energy does the human receive of the original 1,000 units? a. 1b.900c. 10d. 100e. 200

Answer is D

Explanation:

If we start with 1000 units of energy, according with the text, 10%  of those initial units (1000) which are contained in the grass, are passed to the next trophic level, so the cow receives 100 energy units. When tha chain continues, the 10% from the cow passes to the human, which is equal to 10 energy units.

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!

explanation:

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
