Answer 2

## Step1For question 15, it is about the concept of ecological succession. The question is asking us to identify the type of succession that occurs after a landslide. ### **Primary succession** happens in environments that have been newly formed or exposed, such as after a landslide.## Step2For question 16, it is about the adaptation of tigers to different climates. ### **Adaptation** is a process by which an organism becomes better suited to its habitat. ## Step3For question 17, it is asking about the easiest component of biodiversity to measure. ### **Species diversity** is the most straightforward and commonly measured component of biodiversity.## Step4For question 18, it is about the direct economic benefits of biodiversity. ### **Ecotourism** is a direct economic benefit of biodiversity as it involves the tourism industry.## Step5For question 19, it is about a significant event in the mid-1700s that changed human population growth. ### **Industrial Revolution** significantly changed human population growth by increasing life expectancy and birth rates.## Step6For question 20, it is about the combination of factors that will produce the highest rate of population growth. ### **High life expectancy and low infant mortality** will produce the highest rate of population growth.## Step7For question 21, it is about the definition of a population's total fertility rate. ### **Total fertility rate** is the average number of children a female member of the population has during her lifetime.
