Add an id attribute with the value "habitat" to the opening <div> tag that has the Habitat<h2> heading as a child.
There’s a div element that has a child that’s <h2>Habitat</h2>
because <h2>Habitat</h2> is inside that div ; meaning <h2>Habitat</h2> is after the beginning of the div <div> and before the end of that div </div>
