A mule is sterile and cannot reproduce, but still meets the criterion because it is the product or reproduction between two closely related animals (horse and donkey) Living organisms grow and develop in patterns directed at least in part by heredity (traits passed to an organism from its parent/s, through dna) Living organisms use energy to create and maintain patterns of order within their cells, to reproduce, and to grow: life without energy utilization is simply not possible. Obtain energy from the environment: food or chemical interactions. All living organisms interact with their surroundings and actively respond in at least some ways to environmental changes: ex.
