they both are living things
Living things are alive.
Reproduction.
No, living things such as humans and other animals must consume their food, however plants typically derive all the energy they need from the sun, soil, and water. They use the process of photosynthesis to convert sunlight into sugars that they can use as food.
humans seek out new land to build housing and businesses, so they fill in swamps with dirt and rocks to dry them up, and push the swamp land back or decrease it to make room for homes and businesses. sometimes they dig the swampland out and make artificully deepended lakes for low cost property development then sell it as "waterfront" property which is really just old swampland. humans also build sewage systems that dump into swamps because they are careless and don't think about the conseqences of this action. humans may also dispose of other toxic wastes into swampland assuming no one will ever use the swamp as a resource.
Living things reproduce.
the fact that they are alive
humans can have things on their shoes and leave it on the ground to make soil
because they are a part of a human and humans are living things. all cells that make up living things are living. actually, all cells are living, or at least once were alive.
Green plants make food from sunlight. All animals get their food by eating plants (living things) or animals (also living things)
humans make things that are in their way.
Atoms.
