<span>An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system.

Answer:
Enzymes are proteins that bind to a molecule, to modify it and lower the energy required to make it react. ( In other words , enzymes are biological catalysts.
Catalysts lower the activation energy for reactions.
In simple terms , The lower the activation energy for a reaction, the faster the rate. )
The activation energy is the energy needed to start a reaction.
Explanation:
Thus enzymes speed up reactions by lowering activation energy.
