Remembering summer. Living and non-living nature

Everything that formed by itself and was not made by people belongs to nature. Nature is living and non-living. Living nature (organisms) grows, breathes, feeds, moves and has offspring; rocks, water, air and the Sun belong to non-living nature. An animal that eats only plants is a herbivore, one that eats other animals is a carnivore, and one that eats both (bear, human) is an omnivore. A food chain shows who eats whom: grass → grasshopper → frog → snake → eagle. Biologists study living things, geographers the Earth’s surface, astronomers space, chemists substances, physicists motion and changes, and ecologists how living and non-living nature are linked.
