Answer:Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. So enzymes speed up reactions by lowering activation energy
(Basic) kinetic energy and potential energy

Decomposers because they decompose dead organisms, which releases the carbon.
Answer: A Microtubules
Explanation: The cytoskeleton is composed of at last three different types of fibers: microtubules, microfilaments, and intermediate filaments. These fibers are distinguished by their size with microtubules being the thickest and microfilaments being the thinnest.
