I am trying to get rid of Ecosia on my MacBook Air

However, I have searched how to get rid of it and it doesn't work. The advise is to find it in Applications but it is nowhere to be found. I thought it was a great idea to instal it, however it is definitely lacking in comparison with Safari which I prefer. Any advise please? Every time I search in Safari, the answer comes up in Ecosia. Annoying
