Error in foreach - Notice: Array to string Conversion in

Question

I’m having difficulty generating a table using foreach, initially I’m trying to put so that appears the number of the field ID of the animal table in the table, but keeps appearing the error: Notice: Array to string Conversion in C: Users Ulisses Desktop usbwebserver- Tccc root SGS animals_registered.php on line 196

<table>
  <thead>
    <tr>
      <th>Nome do Documento</th>

      <th>Excluir</th>

    </tr>
  </thead>

  <tbody>
    <?php 

include"cone.php";

$sql="SELECT *FROM animal";

$dados = $conn->query($sql);
$rows = $dados->fetch_assoc();

foreach($rows as $key => $value) { ?>


    <tr>
      <a>
