Answer:
increasing[1], higher[2], space[3], food[4], climate change[5].
Explanation:
Because global temperatures are increasing[1], some species are seeking out higher[2] elevations in the Himalayas to colonize. Scientists were worried that these organisms would not have enough space[3] to live, but they have found that there is adequate food[4] at higher elevations. This movement may help these organisms survive the effects of climate change[5].
(Although am positive about 1, 2 and 5, you will need to double check 3 and 4. What I can tell you is that I don't think lifespan has to do with 3 or 4. I chose space and food simply due to the thought that more species moving to higher elevations allows for less space to live, but more prey to be hunted easier.)
