Answer:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Explanation:
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.
<h2>Answer is option "B"</h2>
Explanation:
- Fossils are formed by unusal ways of minerals,energy and other substances. the sap solidifies and frames the semiprecious material called golden. In certain bits of golden the buried survives from living beings can be found. Volcanic ejections can shape fossils when creatures get caught in the hot debris streams. Right now, the fossil is a hole looking like an animal.
- Truth be told coal is the fossil record of entire timberlands; in any case, singular plant structures normally don't make due as the plant materials are compacted to short of what one-hundredth of their unique size. the hard part of plants are remain the fossil.
- So as to get fossilized, creatures must kick the bucket in a watery situation and become covered in the mud and residue.
- hence, the right answer is option B "Plant lived near the poles,but landmasses have drifted to current locations".
Yay so happyyyyyyyyyyyyy for youuu
Answer:
The correct answer would be b. because water provides electrons.
During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.
The overall reaction can be written as:
2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂
It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.
The oxygen is released as the byproduct of photosynthesis.
The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).
The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.
The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.
The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.
