A population of 1,492 finches is introduced to a rainforest. Over the next year, the finches showa death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers) O Yes, this is a suitable habitat. The birth rate is higher than the death rate. D No, this is not a suitable habitat. The birth rate is much lower than the death rate. 589 -358 a 0.155 O 0.845 Which of the following is true of a population approaching its carrying capacity?

The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.

Mclver beetles come in three colors: black, white, and brown. They are consumed by the Foust finch. To avoid predators, the beetles hide on the bark of trees in their environments. If the number of trees with black bark was significantly greater than the number of trees with white or brown bark, what would be the effect on the predation of Mclver beetles by the Foust finches?
