Question

in mediterranean chaparral ecosystems, how do many plant seeds germinate? 1 point
through animal dispersal
via wind pollination
through water absorption
by requiring fire
what makes prairie soils particularly valuable for agriculture? * 1 point
constant moisture
low mineral concentration
extreme fertility
high clay content

Explanation:

1. In Mediterranean chaparral ecosystems, many plant seeds have adaptations such that they germinate after a fire event which clears the area, enriches the soil with nutrients from burnt - material and exposes the seeds to favorable conditions.
2. Prairie soils are highly fertile due to the accumulation of organic matter from the deep - rooted grasses that have grown and decomposed over time, making them very valuable for agriculture.

Answer:

1. By requiring fire
2. Extreme fertility
