If the mitochondria of half the organisms in the ecosystem stopped functioning what indicators in the ecosystem would change

Hello there.

If the mitochondria of half the organisms in the ecosystem stopped functioning what indicators in the ecosystem would change

50%

I think it's quite likely that all the organisms that lose 50% of their mitochondria pretty much die. Perhaps some plants can survive that, but I doubt animals can. Hope this answers the question. Have a nice day. Feel free to ask more questions.
