Discuss how reproductive strategy affects the structure of a population (in other words, compare and contrast r-selection VS k-selection). In your answer, you should provide examples and discuss: the number of offspring and the amount of parental care.

In an r strategy, the reproduction rate will be high, and therefore the natural selection acts on the first stages of development.  

In a k strategy, the reproduction rate will be lower. Therefore, in this strategy, the selection acts on adult organisms, impacting on its fecundity (i.e., its ability to reproduce)

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
