Births, deaths, and emigration/immigration define lifehistory
1a. What are the different strategies for reproduction ofsemelparous and iteroparous pecies? What environmental strategiesfavor each one and why? (Inlude the trade-off strategy indiscussion) (Explain with examples)
1b. Describe 2 organisms that have very different iteroparouslife histories. Describe the environment the organisms grow in andtheir strategies for growth and reproduction. Relate answer to lifehistory for evolution.
(K-strategists are organisms that have pretty low offspringproduction but high parental investment. K-strategists are mostlikely operating in a place where the population is at equilbriumin terms of envrionmental pressures on population size, or a slowlife cycle. R-strategists are organisms that have many offspringbut have small parental investment, r is a value of reproduction,or fast life cycle.)

Semelparous species are those in which the reproduction or mating takes place only once in their life Whole of the resources and energy available with such an organism is used up in mating Iteroparous species are those which are capable of matingreproducing a number of times in their life They do not invest whole of their energy into mating Answer to Q1a As per the information about the strategies provided in the question Kstrategists have lesser offsprings in one mating ie they have comparably lower gamete production per mating cycle but have more parental care which means the organisms following this would have offsprings that are weak on birth and cannot survive on their own they need parental care which is possible only in case of Iteroparous species as See Answer
