A marine ecologist has constructed the conceptual model shown in the diagram. Which prediction can be made from using this model? (3 points) Food web with arrows pointing from phytoplankton to zooplankton, zooplankton and shrimp to menhaden, crabs and lobster along with as well as an arrow pointing from zooplankton to sardines, then from sardines an arrow pointing to shark, tuna and dolphin. © NOCS, February 2007 Where the tertiary consumers get their energy How often primary producers are able to reproduce When bacteria and fungi initiate the process of decomposition Whether other secondary consumers are present

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
