A particular population limiting factor or factors must have been removed
Explanation:
The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.
For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. <u>It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community. </u>
Answer:
C. Most people will die from negative health effects associated with stroke as indoor dirty air builds up.
Explanation:
<u>C is correct option</u> because it shows the highest proportion of people's death caused by stroke. On the other options are not correct due to the following reasons:
A is incorrect because it says that people have a lower risk of dying from COPD. On the other hand, the graph shows that this is 3rd most abundant cause of deaths.
B is incorrect because deaths due to lung cancer are the lowest according to the graphical illustration.
D is incorrect because the proportion of developing acute lower respiratory infection and ischemic heart disease are not the same. Deaths due to ischemic heart disease are higher than the acute lower respiratory infection.
