answer
B)heterotrophs
-autorophs
Encyclopedic entry. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.
-heterotrophs
An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter. All animals, protozoans, fungi, and most bacteria are heterotrophs. Compare autotroph.

Answer:
Convergent Evolution
Explanation:
In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.
The asthenosphere lies 80-200km below the surface under the lithosphere. Convection also occurs in the asthenosphere. The asthenosphere is mostly made of up rock material (magnesium and iron silicates). The asthenosphere makes up 6% of the mantle and lets the lithosphere move.
