Trying to change state of object when Timer reaches zero

public class Timer : MonoBehaviour { public static float time; public static float startTime = 5; public Text countdownText;

 // Start is called before the first frame update
 void Start()
 {
     time = startTime;
     StartCoroutine(LoseTime());
     Time.timeScale = 1;
     countdownText.text = time.ToString();
 }

 // Update is called once per frame
 void Update()
 {
     countdownText.text = time.ToString(); //Showing the Score on the Canvas
     print(time);
 }

 //Simple Coroutine
 IEnumerator LoseTime()
 {
     while (true)
     {
         yield return new WaitForSeconds(1);
         time--;
     }
 }

}

public class BlockBehavior : MonoBehaviour { public static int floorPosition = 1;

 private GridService gridService = new GridService();
 private bool isDrop;
 private bool isSet;
 private GameObject player;
 public float fallSpeed;
 private float fallTime = 0;
 int stopHeight;
 

 // Start is called before the first frame update
 void Start()
 {
     isSet = false;
     isDrop = false;
     player = GameObject.Find("Player");
     
 }

 // Update is called once per frame
 void Update()
 {
     BlockDrop();

     if (Timer.time <= 0)
     {
         print("fall");
         isDrop = true;
         gameObject.name = "FallingBlock";
         Timer.time = Timer.startTime;
     }
     else
     {
         if (Input.GetKeyDown(KeyCode.Space))
         {
             isDrop = true;
             gameObject.name = "FallingBlock";
             Timer.time = Timer.startTime;
         }
     }

}
