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.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
