- Consider two bird species that forage for insects that live in shrubs. The shrubs have a clumped, patchy distribution throughout their habitat. The two bird species have the same ability to locate, capture, and consume the insects. However, one species (species A) uses less energy to fly from patch to patch than the other species (species B). According to the marginal value theorem, which bird species should spend more time in each patch, and why?arrow_forwardWhat is coevolution?

"Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another."

- During the drought of 1977 on the island of Daphne Major, which of the following answers correctly explains why birds with larger beaks had a competitive advantage over other individuals? These birds were able to hold more water. These birds were able to fight off birds with smaller beaks more successfully. These birds were able to smell and locate nesting sites with more accuracy. Birds with larger beaks were better able to utilize the large seeds.arrow_forwardwhat are 4 mutualistic interaction between two or more species that are exploited to improve agricultural production or food productionarrow_forwardWhat are 4 beneficial (mutualistic) and 4 harmful (antagonistic) interaction between two or more species that are exploited to improve agricultural production or food production.arrow_forward
- What is the difference between a K-strategist and an r-strategist? K-strategists and r-strategists differ in the longevity of life and the number of offspring. K-strategists have a longer life span but produce fewer offspring, and r-strategists have a shorter life span but produce more offspring. K-strategists are species whose generations consist of short-lived organisms that produce no offspring, and r-strategists are species whose generations consist of short-lived organisms that produce few offspring. K-strategists are species whose generations consist of long-lived organisms that produce many offspring, and r-strategists are species whose generations consist of short-lived organisms that produce few offspring. R-strategists are species whose generations consist of long-lived organisms that produce few offspring. In contrast, K-strategists are species whose generations consist of…arrow_forwardQuestion 4: Does production of high density of leaf hairs affect the response to competition?
