Question

1. which is not true about animal species? a. animals of the same species can interbreed and reproduce b. endangered species are in immediate jeopardy of extinction c. individual species are well - documented on a central registry d. some species have been protected through trade restrictions 13. which type of strategists would you expect to have low levels of prenatal care and a short life expectancy? a. k strategists b. s strategists c. r strategists d. j strategists 14. long life expectancy usually correlates with all the following, except: a. high levels of prenatal care b. larger animals c. type 1 & 2 survivorship curve d. rapid reproduction 15. which of the following is not a density - dependent factor? a. storms b. disease c. competition d. predators answer 3 of the questions below on the back of your zipgrade. use full sentences. 3 types of survivorship curves and label each with the correct type. ample of an animal that is an r strategist and explain why. ypothetical situation in which a species would be separated by temporal speciation. rinciple of competitive exclusion? graphs. one should show logistic growth one should show exponential growth

Explanation:

1. Endangered species are not always in immediate jeopardy of extinction and not all are well - documented on a central registry.
2. R strategists have many offspring, low prenatal care, and short life expectancy.
3. Rapid reproduction is not correlated with long life expectancy. Long - lived species usually have high prenatal care, are larger, and follow type 1 or 2 survivorship curves.
4. Storms are density - independent factors, while disease, competition, and predators are density - dependent as their impact varies with population density.
