Answer: It's definitely a. Prokaryotic are organisms that don't have membrane bound organelles or a true a nucleus. Scientists theorize that single, cell Anglophile organisms started in the primoridial soup. Through the endosymbiotic cell theory, it is believed that plastids engulfed free floating mitochondria and began the grassroots for life

After a natural disaster such as a hurricane or tornado what will happen in the damaged ecosystem
RUDIKE [14]

After a tornado or a hurricane the local ecosystem will be very damaged, and when the wind stops blowing, or all the water is drained/dried, the ecosystem will start recovering:

  • The earth will recover
  • Plants will regrow.
  • Animals will come back.
  • The ecosystem will slowly rebuild.

Hope it helped,

Kay [80]
<span>The choices for this question are:
</span>-is biologically magnified in ... are recycled in
-is dissipated in ... flow through
-flows through ... are recycled in
-is continuously supplied to ... are continuously removed from
<span>-is recycled in ... flow through</span><span>

On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option. 

Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.  
</span><span>
Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled. 

In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>
