Question

question 3
identify and describe the protist that was responsible for the irish potato famine of the 1840s.
protozoa
brown algae
slime mold
water mold

Explanation:

The Irish Potato Famine in the 1840s was caused by a water mold (a type of protist) called Phytophthora infestans. Water molds are protists that can cause plant diseases, and Phytophthora infestans infects potato plants, leading to late blight, which devastated potato crops in Ireland. Protozoa are animal - like protists, brown algae are a type of algae (not related to potato blight), and slime molds have a different ecological role and are not responsible for the potato famine.

Answer:

D. Water mold
