What is the definition of an ecosystem
is a geographic area where plants, animals, and other organisms, as well as weather and landscape work together to form a bubble of life
What is the definition of a habitat
a place where an organism makes its home. this must meet all the environmental conditions an organism needs to survive.
What is the definition of a biome
a biogeographical unit consisting of a community that has formed in response to the physical environment in which they are found and shared regional climate. or is a broader term than habitat and can comprise a verity of habitats,
What is the definition of species

How do food chains always begin
autotroph or producer
What are tropic levels
feeding levels in a food chain
Give the definition of of a food chain
A food chain is a series of organisms in an ecosystem in which each organism eats the one below it and is consumed by the one above it
