Which statement best describes the energy flow as it passes from producers to tertiary consumers?
A. 10% of the energy is transferred through each trophic level.
B. 100% of the energy produced passes to each trophic level.
C. 50% of the energy produced is transferred through each trophic level.
D. 1% of the energy is lost as heat is transferred through each trophic level.
Answers
Answer:
The answer is A
Explanation:
At any given trophic level, only 10% of the energy is transmitted to the next level; the remaining 90% is primarily wasted as heat during metabolic activities. Thus, option A is correct.
What is the role of energy flow in an ecosystem?Typically, only 10% of energy is transmitted from one trophic level to the next. This restriction on the number of trophic levels that an ecosystem may support is referred to as “the 10% rule.” organisms that are alive and the energy they hold.
Each trophic level's energy content diminishes as it progresses through an ecosystem.
The 10% Rule states that only 10% of the energy will be transferred when it moves from one trophic level to the next in an ecosystem.

5. Why are metamorphic rocks formed by contact metamorphism usually not as dense as those
formed by regional metamorphism?
Answers
Answer:
The rock was altered by high temperature with extreme pressure
Explanation:
Fossils would be destroyed
Metamorphic rocks formed by contact metamorphism are usually not as
dense as those formed by regional metamorphism because of their mode of
formation which involves a higher temperature without little or no pressure.
Contact metamorphism involves rock formation as a result of contact with
hot magma. The regional metamorphism involves the formation of rocks
deep in the soil through extreme temperature and pressure over a wider
area.
This is the major reason why the metamorphic rocks from contact
metamorphism are denser than the regional metamorphism.

с

D

Answers
A growling stomach and the stimulation of hunger represent the digestive system and the nervous system working together. The correct option is c.
What is hunger?Hunger is primarily a biologically induced desire for food, which is required for survival.
Hunger can thus be regarded as a quantifiable biological trait of humans that predicts the willingness to eat as well as the amount of food consumed.
During fasting, the stomach secretes the "hunger hormone" ghrelin to promote food intake.
Ghrelin stimulates appetite by activating its receptor GHSR1a in the brain's hunger sensing neurons, and thus represents a promising avenue for the development of anti-obesity treatments.
A growling stomach and the stimulation of hunger represent the digestive and nervous systems collaborating.
Thus, the correct option is C.
