A transition is one to two words used to basically start another paragraph, topic, or sentence. These can be used at the ends or beginnings of paragraphs depending on where they best fit.
So now that we know what a transition is, we can see them in the examples I will give you :)
So most animals are neutral, however; Some are aggressive. These animals can include bears, lions, panthers, etc.
This is why we need better food in schools, for example; four chicken nuggets and an apple wouldn't fill an adult so why serve it to a growing teen?

I hope this helped. Have a great night!
