Question

Explain what extinction threats a frog living on a mountainside in Costa Rica might face.

Short answer

the frog is at the risk of global warming shifting its preffered habitat up the mountains

Step-by-step solution

Step 1. global warming

Excessive use of fossil fuels also leads to global warming which leads to destruction of the habitat .Climate gradients will also move up mountains, eventually crowding species higher in altitude and eliminating the habitat for those species adapted to the highest elevations. Some climates will completely disappear. The accelerating rate of warming in the arctic significantly reduces snowfall and the formation of sea ice.

Step 2. melting of glaciers

Finally, global warming will raise ocean levels due to meltwater from glaciers and the greater volume of warmer water. Shorelines will be inundated, reducing island size, which will have an effect on some species, and a number of islands will disappear entirely.
