Answer:
Environmental impacts of particles, such as dust and  smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem
Environmental impacts of greenhouse gases released from livestock  production -  increase in atmospheric temperature 
Explanation:
Environmental impacts of particles, such as dust and  smoke, released from livestock production - 
Release of particles such as  dust and  smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs. 
These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc. 
Environmental impacts of greenhouse gases released from livestock  production - 
Green house gases will lead to increase in atmospheric temperature

Is there a picture you forgot to post with the question?
In the problem you mention, which I assume comes from the study of finches in the Galapagos, some birds evolved to have different beaks, depending on the food available. Depending on what kind of seeds there are, different beak sizes were selected for, with those with the right fit eventually winning out over the rest on the individual islands.
 
        
             
        
        
        
The right answer is hyphae for the first gap, mycelium for the second gap.
The hyphae constitute the vegetative apparatus of the mushrooms, while the visible part, that which is improperly called mushroom, is in fact its reproductive apparatus.
Hyphae are less branched filaments consisting of a single cell that can be several centimeters long. They contain several nuclei and can sometimes be partitioned.
The mycelium is a part of the mushroom (composed by many hyphae), which is in the form of white filaments and grows about fifteen centimeters under the ground. It is this part of the mushroom that has therapeutic properties because the filaments of the mycelium are going to draw the minerals in the soil.
 
        
             
        
        
        
Well, depending on how long the migration is, many of the animals (mainly birds) could get sick and die, lowering the population. They could be shot by hunters, lowering the population. The children of the population could get left behind and lose their way, lowering the population. I'm not entirely sure how the population could grow other than them finding and staying with another group of their own kind. hope I was helpful! :)
