Answer:
Option B
Explanation:
In biology, fitness refers to the ability of an organism to survive, reproduce, mate and support evolution through gene transfer. A fitness of 0.28 signifies that only 28 percent of a given population are fit physically and able to reproduce while the remaining 72 % are unable to mate and hence cannot reproduce and contribute towards gene flow and evolution.
Hence, option B is correct
Rotary, oscillating, linear, reciprocating
Let me try...
How about, grass, moose(moose eats grass), black fly(when moose dies it's eaten by fly), fish(fish can catch flies sometimes), and then Osprey(birds eat fish).
The second one... How about, grass, deer(deer eats grass), then wolf(eats deer), the mosquito(sucks wolf's blood), I don't know the dragon fly though
HOPE THAT HELPED SOMEWHAT :)
