I have 2 examples down below! 

Apple tree: An apple tree produces apples or the fruit of the tree using photosynthesis. Photosynthesis is very important without it no energy will be provided in order to produce the offspring ( in this case apples). 

Human: Humans need the nutrients of food in order to stay active, lead healthy lives, and reproduce. Without nutrients we humans wouldn't be able to thrive.
