In comparison they both show feeding relationship in an ecosystem.
In contrast, a food chain is a simple linear feeding relationship while a food web is a complex feeding relationship.
2) The arrows is to show the direction of the feeding relationship
Explanation:
<h2>Answer:-</h2>
In case of Figure A and B,
- The work is being done perpendicular against the gravity. And we know that when work is done perpendicular to gravity, then zero work is done.
For Example:-
We also need to know that work done in circular motion is zero.
So, work done by electron to orbit around a proton is also zero.

Viruses are much smaller then cells, viruses have genetic material DNA or RNA and cells also have genetic material
