Fertilizers used to improve lawns and gardens can interfere with the equilibrium of an ecosystem. Why is this true? A They can be carried into local water supplies. B They cannot be absorbed by roots. C They cause mutations in all plants. D They can reduce atmospheric pollution.

Option A

Explanation:

The fertilizers that is being supplied into the plants contains huge amount of nitrogen and phosphorus in it. The extra fertilizers from the ground move to the nearby local water bodies.

These nutrients n water serves as the food for the algal and make them grow at higher growth rate.

They start consuming the oxygen in water and thus affecting the other aquatic animals found in water.

Because of this reason there is a disturbance in the equilibrium of ecosystem as if the aquatic animals will die there will be a decrease in the population of animals feeding on aquatic animals.  

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.

ur answer is e & d
