Iti do a cohort study on some new cute animal, and I discover that most of the individuals die at a relatively young age, and only a few live close to the maximum age for the species, what
would you predict about the reproductive strategy of this species?
O They probably produce relatively few offspring and invest a lot of parental care into each offspring.
O They probably produce a lot of offspring, and invest a lot of parental care into each one.
O They probably produce a lot of offspring but do not invest much parental care in any individual offspring
O They probably produce offspring only after individuals manage to live to close to their maximum age

During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Offspring are left to develop, hatch, and grow on their own, maturing in about three months.arrow_forwardMany factors influence a species mode of reproduction. Use the descriptions of the following species to predict what system of hermaphroditism they probably display. 1. Individuals rarely disperse once they are sexually mature, and the largest males get the most matings. Females protect the eggs. [Select] 2. Resources are of uniform quality and evenly dispersed, so males are unable to monopolize them. Females are larger than males; Males protect the eggs. [Select] 3. Individuals are solitary, rarely meet others, and have no way of knowing the sex ratio in the population. There is no parental care.
