Question

question 20
which most likely describes a seed dispersed by animals?
o enclosed in a seed pod that opens quickly when it dries out
o attached to a structure that looks like a sail
o light, buoyant, and hollow
o surrounded by a seed coat that is not easily digested

Explanation:

• For the first option, a seed pod opening when dry is typical of self - dispersal (explosive dehiscence), not animal - mediated.
• The second option (structure like a sail) and third option (light, buoyant, hollow) are adaptations for wind or water dispersal.
• Seeds with a hard - to - digest seed coat can pass through an animal's digestive system unharmed and be dispersed in the animal's feces, which is a common mechanism of animal - mediated seed dispersal.

Answer:

D. surrounded by a seed coat that is not easily digested
