Wordpress taxonomy, what php file template is needed?

Question

Taxonomy

Help me to understand.
I display taxonomy for nesting pages.
I display it on the main page (index.php), when I click I stay on the main page (index.php)
I looked at the Visual Overview section on the official website, but I didn’t understand.
Which template file should be used for the taxonomy?
Output codes.
$cur_cat = get_query_var('cat');
if ( is_home() )
{
$new_cat = wp_list_categories('taxonomy=media_cat&echo=false&child_of=' . $cur_cat . '&depth=2&title_li=&&show_count=1&show_option_none=&&hide_empty=1');
echo($new_cat);
}
taxonomy adding function code:
function init_media_categories() {
register_taxonomy( 'media_cat', '
'label' => __( 'Categories' ),
​​'hierarchical' => true,
'public' => false,
'show_ui' => true,
'show_admin_column' => true,
'update_count_callback' => '_update_generic_term_count',
' rewrite' => array( 'slug' => 'media' ),
) );
}
add_action( 'init', 'init_media_categories' );
