All of the living organisms on earth make up the biosphere. The biosphere is the global entirety of all ecosystems in ecology. All of life on earth exists in the region known as the biosphere
This includes all life forms and their interactions with the elements of the atmosphere, hydrosphere, and lithosphere.
Simply put, the biosphere is the area of the Earth’s surface where land, air, and water connect to sustain life.

All environments on earth that support life
All environments on Earth that support life are known as ecosystems.
A simple definition of an ecosystem is a group of interacting organisms both living and non-living, that inhabit a particular place known as the habitat.
It can also be described as a community of living and non-living entities that co-exist and affect each other either directly or indirectly.
All of the following are true of all living organisms except
All of the following are true of all living organisms except they are not all multicellular. Some organisms are unicellular or single-cell organisms.
Unicellular organisms include diatom and yeast.
It is true about all living organisms in a habitat that all living organisms are made of cells.
For approximately 2 billion years, unicellular organisms existed alone on earth before the multicellular organisms manifested.
All living organisms that inhabit an environment require energy to survive. Energy can be obtained by an organism one of two ways.
The first way is the organism can produce its own energy. Plants create their own energy via photosynthesis.
The second way an organism can obtain energy is by consuming another organism. Herbivores and carnivores obtain their energy via this method.
All organisms and the part of earth where they exist
All organisms and the part of earth where they exist are known as biomes. A biome is a natural ecological environment that allows interaction between various plants and animals.
Examples of biomes are desert biomes, tundra biomes, and chaparral biomes.
Biomes allow ecologists to categorize organisms in large ecosystems associated with a specific geographic region. All of the organisms in a given location or area are termed an ecosystem.
Broken down further all animals in an ecosystem that are the same species are known as a population.
In science, the study of the distribution of animals and plants around the world is known as biogeography. Due to adaption abilities of organisms, there is a wide variety of organisms able to adapt to various environments on earth.
Division containing plants animals and fungi
The division containing plants animals and fungi is eukaryotic organisms. Eukaryotic organisms all contain eukaryotic cells.
These cells have a nucleus surrounded by a nuclear membrane. Eukaryotic cells also contain membrane-bound organelles.
Eukaryotic cells are different from prokaryotic cells. Prokaryotic cells do not have a nucleus. They are also primarily single-celled organisms. Eukaryotes are primarily multicellular organisms.
Examples of environments on earth in which life is found
Examples of environments on earth in which life is found are:
- The tundra environment
- The desert environment
- The forest environment
- The ocean environment
- The rainforest environment
- The mountain environment
In what way are all living organisms on earth similar
The way all living organisms on earth are similar is that all living organisms contain cells. Cells are the building blocks of life.
No living organism can exist without cells.
Another similarity between all living organisms on earth is that all living organisms require energy to survive.
Organisms obtain energy by producing it themselves or consuming other organisms. This helps ecologists categorize organisms into producers and consumers.
Matter contained in living organisms
Matter contained in living organisms all consists of cells. Within cells are a variety of organelles and molecules that perform different functions.
Examples include the golgi complex, ribosomes, and mitochondria.
Why are humans able to live in a variety of places on earth
Humans are able to live in a variety of places on Earth because they can quickly adapt to almost any environment. Humans have high intelligence compared to most other animals.
This high intelligence allows humans to build the necessities for survival in a variety of places on earth. Examples include shelter, access to water, and access to food.
