ELI5: How does grass survive the winter with months of snow cover, but it can't survive a cooler placed on it for a week in the summer?

Every spring, my grass comes in full and thick.  I live in the north where a month of snow cover is common.

But after throwing a party, the grass will die if I leave a cooler on it for a week.

Grass goes into a dormant state as the weather changes, similar to how trees shed their leaves and go dormant. With the lowered state of metabolism, among other augmented processes, these plants can survive a winter. Imagine a car operating with 2 of its 4 cylinders disabled. It will still run, although at a low performance, and will consume FAR less gas. When the grass is back in full on summer mode it needs a consistent supply of energy and nutrients to stay alive. Nutrients and water it can retrieve from the ground, but the light from the sun needed for photosynthesis (making plant food) has been blocked by your cooler. At this point your grass, which is running with all 4 cylinders, has no gas. The grass will die.
