Answer:
"Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up." By the way this is from the internet but from what I read it should be false mark brainllest if you want.
Explanation:
Answer:
1In a hypothetical food chain consisting of grass, grasshoppers, sparrows, and hawks, the grasshoppers areprimary consumers. primary producers
Explanation:
Oxygen, Carbon, Hydrogen, Nitrogen and Phosphorus.
Answer:
Energy retained at consumer level 1 - 100 units
Energy retained at consumer level 2 - 10 units
Energy retained at consumer level 3 - 1 units
Explanation:
The total units of energy lies at the producer level of the energy pyramid.
Now at each trophic level only 10% of the energy of its previous level is passed on which means at
Consumer level 1 -
energy retained % energy at producer level
units
Like wise -
Energy retained at consumer level 2 -
units
Energy retained at consumer level 3 -
units
Thus,
Energy retained at consumer level 1 - units
Energy retained at consumer level 2 - units
Energy retained at consumer level 3 - units
