To fill:

The blanks in the given figure.

Introduction:

Extinction vortex is a model that helps the ecologists, biologists, and geneticists to determine the reason for the extinction of the species. This model reveals the causes that lead to the vulnerability of the small populations, as they spiral toward the extinction. This model was developed by M. E. Gilpin and M. E Soule in 1986.

Explanation of Solution

The given figures are the depiction of a graph which determines the amount of biomass of grass population transferred to mountain lions. The grass is an autotroph and makes its own food by the help of photosynthesis. When deer eat this grass, then only 10% of the energy in the grass is transferred to the deer. Further, when the lion eats the deer, then again, only 10% of the energy taken by the deer is transferred to the mountain lion.

What would the extinction rate be for a 30 square mile island that is 1000 miles from the mainland and has 150 species on it. Assume the extinction probability for each individual species is 0.8 and the power scaling function is 0.25. Round your answer to two decimals, include a 0 before the decimal if necessary, and do not include units (i.e. O.XX)
Estimates indicate the average annual background extinction rate is approximately one species lost for each million species on the earth per year. True False

A biologist for Mosaic fertilizer company catches 26 Florida scrub jays as part of their monthly environmental monitoring. Each bird is given a band. The next month, they catch 32 birds. 13 of the birds have bands. What is the estimated population size of the birds in that area?
