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.
It would be the sinoatrial node and atrioventricular node.
Hope This Helps You!
Good Luck Studying :)
Answer:
D
Explanation:
At the very end it says how the water level has to be just so for the eggs to not dry out, but not too deep either or they cannot get sunlight
It never mentions time so it is not A or any type of fish so its not C
or time of year so its not B, leaving us with A
I really hope this helps u!
Pls give a brainliest and a thx ;)
<span>Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein</span>
