(Solved): not sure if 10 is a or b could you help?is 2 correct. growth pattern options are logistic and e ...

The world population reached seven billion in 2011. At current growth rate, it is expected to reach eight billion by 2024 and nine billion by \( 2037 . \) However, many projections predict that the world population will level off at around 9 billion individuals. Why is the world population expected to level off? a. The global fertility rate has been decreasing for the past 20 years and is expected to decline even further. b. The Earth's carrying capacity is estimated at 9 billion individuals, when the global birth rate and death rate become equivalent. c. More than a third of the world population is expected to be aged 60 years or above in 2100 . d. Recent technological and medical advances led to increased life expectancy, allowing individuals to live longer. Clear my choice Sea otters are marine mammals that live in northern Pacific coasts. Typical female sea otters reach sexual maturity around 3 or 4 years of age, and they reproduce once a year, producing a single pup. Only female sea otters are tasked with raising the offspring. Mothers constantly take care of their pups until they are 8 months old, but only \( 25 \% \) of the pups survive past the first year. Their main food source is sea urchins, molluscs, and crustaceans. As a population, sea otters could be classified as a. K-selected because only 1 pup is born per year b. K-selected because only females take care of the offspring c. r-selected because of the relatively long period of parental care d. r-selected because they are highly dependent on sea urchin population as their main food source Clear my choice Use the following to answer the next question. Match each organism to the most likely life strategy and growth type.
