Answer:
Because there is less energy at higher trophic levels
Explanation:
- In a food chain that shows the feeding levels of organisms in an ecosystem, energy decreases as you move from the lowest trophic level to the highest trophic level.
- The lowest trophic level consists of producers which have the highest energy as they trap energy directly from the sunlight.
- The energy is lost from one trophic level to the next up to the highest trophic level which has the lowest energy.
- Therefore, organisms at the highest trophic level are fewer in number but large in size.
The sun is the centre of our solar system
Unlike a ball, an atom doesn't have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance... Does that answer your question?
Answer:
When a magnet causes a paper clip to move, it's an example of Potential energy being changed in to Kinetic energy
A child running is an example of Kinetic energy
A motionless iron object in the magnetic field of a magnet may be said to have Potential energy
I believe the answer is B.
