Explanation:

In ecological succession, plants come first as they are primary producers. They perform photosynthesis to make food, which forms the base of the food - chain for animals. Animals rely on plants for food, shelter, etc. Also, not all plants require pollinators (e.g., some plants reproduce asexually), animals are not needed to regulate plant populations in the beginning of succession as plants can establish themselves first in a barren environment, and plants are less mobile than animals.

Answer:

Plants come first because animals rely on them for food production.
