Explanation:

Ecological succession begins with pioneer plant species that can colonize barren environments (like bare rock or soil). These plants produce organic matter and create a food source, which is a prerequisite for animals, as most animals rely on plants directly or indirectly for food and habitat. The other options are incorrect: animals cannot survive without plant-based food sources first, not all plants need pollinators, plants are less mobile than animals, and they do not colonize simultaneously.

Answer:

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