Final answer:
Plants and animals have evolved and adapted to different environments throughout Earth's history. The colonization of land by plants occurred during the Ordovician period. Plants are autotrophs and animals are heterotrophs, with different characteristics and lifestyles.
Step-by-step explanation:
Plants and animals have evolved and adapted to different environments throughout Earth's history. In terms of geological eras, the colonization of land by plants occurred during the Ordovician period, more than 500 million years ago. This marked a significant event in the evolution of plants on land.
Plants and animals have different life styles and characteristics. Plants are autotrophs, meaning they can produce their own food through photosynthesis, while animals are heterotrophs and obtain their nutrients by consuming other organisms.
It is important to note that plants and animals belong to two different domains of life. Plants belong to the domain Eukaryota, within the group Archaeplastida, whereas animals belong to the domain Eukaryota, within the group Opisthokonta.
