A beautiful wood desk you may do your homework

Answer:

Living things are very well put together, which means that their parts are specialised and work well together. Cells, which are the basic building blocks of life, make up every living thing. Even unicellular organisms are complex!. Organisms can be put together in many different ways, such as with cells, tissues, organs, organ systems, and organisms. There are also levels of organisation above the individual organism. The population, the community, the ecosystem, the biome, and the biosphere.
