Question

the tundra only has low growing grasses and shrubs. why?* your answer this is a required question

Explanation:

The tundra has a short growing season and permafrost (permanently frozen subsoil). The short growing season limits the time plants have to grow tall. The permafrost prevents deep root growth, so plants can't access enough nutrients and water to support tall growth. Low - growing grasses and shrubs are better adapted to these conditions as they have shallow root systems and can complete their growth cycle within the short growing season.

Answer:

The tundra has a short growing season and permafrost. The short growing season limits growth time, and permafrost restricts deep root growth. Low - growing grasses and shrubs with shallow roots and ability to grow quickly in a short season are adapted to these conditions.
