Answer:
Analogous or convergent structure.
Explanation:
Analogous structures can be defined as structures that have similar purposes but look completely different from each other. in other words it means that they serve the same functions in different species, but they are independently evolved. Examples of analogous structures are
- wings on butterfly, bats and birds

<span>Trophic level—90% of energy consumed at trophic
level is used by the consumer for survival and reproduction. The remaining 10%
is transferred to the next trophic level. So the answer is 10,000 x 0.9
or 9,000 calories will be generally available
to primary consumer</span>
Answer:
More info given below.
Explanation:
This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.
