1. How is grass able to recover and regrow so quickly after a fire or grazing by a huge herd of herbivores?

The correct answer is - part of the grass remains safe underground and the base of the grass leaves.

Explanation:

Grasslands are the ecosystem in which grasses survive wind, fire, grazing by a large herd of herbivores and many more as their root and the intercalary meristem present at the base of grass leaves remain underground or did not affect.

These parts of the grass are essential as these parts have a cell that is able to produce new tissue, they are present at the base of grass leaves. In the fire or grazing, the upper part of the grass affected but the cells present at the base of grass remain safe and helps in regrow and recover quickly.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
