Which organisms appeared on earth first

The organisms which appeared on earth first was bacteria.

Explanation:

Bacteria.

Explanation:

The first living beings on the Earth, were the single-celled organisms called as micro-organisms or the microbes that lacks a cell membrane or cell nucleus known as Prokaryotes, seems to be appeared first on the Earth almost 4 billion years ago, which was just a few 100 million years subsequent to the Earth formation itself. Considerably, the longest part of the life history on the Earth, thus, involved the biochemical development of these unicellular micro-organisms, such as bacteria and archaea.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
