A. It sharply decreased their population.

Explanation:

This is the greatest short-term effect of Spanish colonization on American Indians. Colonization brought many negative and positive effects on American Indians, but the most immediate and significant one was a sharp decline in their population. This was due to the diseases that the colonizers carried. As the Native Americans were not resistant to them, many died shortly after their arrival, decimating the population.

The Yellowstone River ecosystem can support 2,300 bald eagles. This is an example of temperate- zone ecosystems

Explanation:

Yellowstone National Park is a natural  paradise with over 70 species of birds,which  include  trumpeter swans, sandhill cranes, loons, peregrine falcons, osprey and bald eagles

The Greater Yellowstone Ecosystem, with Yellowstone at its core, is one of the largest nearly intact temperate- zone ecosystems on Earth. It has an area of 12–22 million acres; 18,750– 34,375 square miles

Temperate ecosystems are the ecosystem that are characterized by the  seasonality in temperature, with cooler winters and warmer summers, and also  show various  seasonality in precipitation patterns, resulting from seasonal changes in the orientation of Earth's axis relative to the sun.
