How are producers related to primary consumers in an ecosystem? a. producers eat primary consumers. b. primary consumers eat secondary consumers, which rely on producers for food. c. primary consumers eat producers. d. producers and primary consumers compete with each other for food sources.

   C. Primary consumers eat producers.

Explanation:

  Producers in an ecosystem are those organisms that by the use of photosynthesis capture solar energy, water, and carbon dioxide to create energy and produce molecules like proteins and lipids that are crucial for life.

  These molecules that the producers create are the ones that the primary consumers eat to survive.

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.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
