Answer:
Zebra mussels are spread from one body of water to another by natural flow, carried on the feathers or feet of birds, or by humans in bait buckets or on boats.
Answer:
increasing[1], higher[2], space[3], food[4], climate change[5].
Explanation:
Because global temperatures are <u>increasing[1]</u>, some species are seeking out <u>higher[2]</u> elevations in the Himalayas to colonize. Scientists were worried that these organisms would not have enough <u>space[3]</u> to live, but they have found that there is adequate <u>food[4]</u> at higher elevations. This movement may help these organisms survive the effects of <u>climate change[5].</u>
(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.)
