Pick the answer that best evaluates the following statement: "it has been said that land animals can't exist without plants but that plants could exist without animals."
a. this statement is incorrect because the animals must supply the detritus for the decomposition process that supports plants.
b. this statement is incorrect because animals are the only source of carbon dioxide that plants need for photosynthesis.
c. this statement is true because plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants.
d. this statement is incorrect because plants can't reproduce without the energy of animals, and animals cannot reproduce without the energy of plants.

c. This statement is true because plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants.

Explanation:

Green plants are autotrophs. They synthesize their food in the presence of sunlight, using carbon dioxide gas and water. Whereas animals are heterotrophs, they cannot make their food but use food prepared by green plants. Thus, plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants. The statement is true.      

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.
