28. Population:

    C) A group of the same species living in the same geographic area

29. Organism:    

   A) Any living thing and it depends on the Earth Systems for survival

30. Community:

    D) All the different organism living in the same geographic range

31. Environment:

    E) Everything around us

32. Biosphere

    B) All life on Earth

Explanation:

Living things are organized into different levels. They can be studied at the smallest level or cellular level to a bigger level which is biosphere. Scientists do not only study the living things alone, but they also study how they interact with each other,  with their environment ( which includes the non-living things.)

Cell →  Tissue →  Organ →  Organ System →  Organism →  Population →  Community →  Ecosystem →  Biosphere

In terms of your question, you can arrange the levels from smallest to largest:

Organism → Population →  Community →  Biosphere

Organisms are made up of organ systems that work together to serve different functions to keep the organism alive.

Ex. Giraffe

Population is a group of organisms of the same species that live in the same area.

Ex. Giraffes in Africa

The different populations make up a community that interact with each other in the same geographic range.

Ex. Giraffes, Zebras, Lions in Africa

Biosphere is all the living things. So this means it encompasses all biological levels.

environment - this is everything around the organisms. This includes abiotic factors as well like climate, resources such as water, light and air.
