Answer 2

Muscle is a type of contractile tissue found in animals that helps them move.

1. The way an organism interacts with its environment is through movement, which is the complicated coordination of muscle and nerve fibres.
2. Muscle cells, or fibres, are innervated, which allows an animal to carry out its daily duties.
3. An organism must either move to get food or have the ability to transport food to itself if it is sedentary.
4. An animal's ability to transfer nutrients and fluids throughout its body, as well as react to external and internal stimuli, is required.
5. Muscle cells generate mechanical energy by converting chemical energy in the form of adenosine triphosphate (ATP) obtained from food metabolism.
