Unsubscribe from subscription in Angular component(subscription gets and proceeds response)

Question

I'm very new in Angular and have a question. I have a service where http methods are called and component where I have subscription on methods results(procced result, open modal, off loading banner and pass it to component). Should I unsubscribe from these subscriptions in onNgDestroy method?(also I have post and put methods in service and subscription on them in component) thanks in advance! Method from component:

    openEditUserModal(id) {
      this.isLoading = true;
      this.rulesManagementService.findUser(id).subscribe(response => {
        if (response) {
          this.isModalOpen = true;
          this.user = user;
          this.isLoading = false;
        }
    }, error => this.handleError(error)); 
  }

Method in service:

   findUser(id: number): Observable<User> {
    return this.httpClient.get(url).pipe(
      catchError(handleError),
      map(value => new User().deserialize(value))
    );
  }
