Describe how the barred owl population is having a negative effect on the spotted owl population

 Barred owl population filled the niche of a spotted owl and the rapid expansion of the barred owl into the range of the spotted owl occurred. The barred owls are a little bit larger, more aggressive and have a wider variety of prey species than spotted owls. Also, barred owls nest more often and successfully, thus producing more young than do spotted owls. This gives barred owls a competitive advantage over spotted owls and as a result, spotted owl populations are rapidly declining in many areas.

Mitochondria is the cell organelle that produced the energy that is needed in the body system in form of atp, that is why it is called the power house of the cell. energy is needed by the living organisms to carry out the activities which sustain life.  if the mitochondria is destroyed atp will not be produced. if the mitochondria is destroyed, energy production will stop and the affected living organism will not have the energy to carry out the necessary life processes; this will lead to the death of the organism.
