Plants evolved before animals.
Animals and plants have separate evolutionary paths. They both evolved from a common ancestor but took different paths in their development. Plants evolved from ancient photosynthetic bacteria, while animals evolved from multicellular organisms that were different from plants.
Yes, plants evolved before animals in the evolutionary timeline.
animals, plants, and fungi
Because they Evolved and developed that way.
Because they Evolved and developed that way.
the way they live there lives mean that they have evolved to need the nutrition that can only be provided by eating both meat and plants.
The animal that first evolved, I guess. But no one knows what that was (because it lived millions and billions of years ago) or if there was an animal that evolved before all other animals. It would have eaten plants though because plants are plants, not animals and they use photosynthesis to survive.
Plants do not actively get nutrients from animals. Instead, some plants have evolved to form mutualistic relationships with animals, such as certain types of carnivorous plants that capture and digest insects for additional nutrients.
When plants and animals evolved, this made changes in the atmosphere on Earth
No planet has truly unlimited oxygen. Life on earth is able to reuse the oxygen in the air by cycling it back and forth between plants and animals (including people).
Plants survive by photosynthesis, using sunlight to produce energy. Animals survive by obtaining food, water, and shelter to meet their basic needs. Both plants and animals have evolved various adaptations to help them survive in their respective environments.
