Question

select the correct answer.
typically, how are large animals such as cows and horses poisoned?
a. they eat too much hay or grains.
b. they eat food mixed with dust and waste water.
c. they eat leftover medicines used by humans.
d. they eat toxic plants or weeds present in their pastures.
e. they drink too much water.

Explanation:

Large grazing animals like cows and horses often forage in pastures where toxic plants/weeds (e.g., ragwort, nightshade) may grow. Ingesting these toxic vegetation is a common cause of poisoning. Overeating hay/grains (A) causes digestive issues, not poisoning; dust/waste water (B) causes infections; human leftover meds (C) are less typical; overdrinking water (E) causes water intoxication, not poisoning. Thus D is correct.

Answer:

D. They eat toxic plants or weeds present in their pastures.
