Which aspects of the angiosperm life cycle have been most influenced by interaction with animals?

The dispersal of seeds.

Explanation:

Fruit and seed dispersal is an important mechanism for angiosperm plants as it allows colonization of new areas. This factor is fundamental for the survival of new individuals, as several copies in the same area trigger competition for resources.

Fruit and seed dispersal can occur by wind, water or animals. When dispersed by animals, the dispersion is called zoochory and can occur in three main ways: fruit ingestion and seed release (endozoocoria), conscious fruit and seed transport (synzoocoria), and fruit and seed transport accidentally (epizoocoria).

Endozoocoria and sinzoocoria are closely related to fleshy and colorful fruits, since in these cases the animal is usually looking for a way to feed itself. The epizoocoria is not normally associated with food, but rather with the structures that make fruits and seeds attach to the animal's body. In this case, fruits and seeds with hooks, thorns and peels that are easily fixed are common.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
