What are all the living organisms on Earth called?
INTRODUCTION. The biosphere is the region of the earth that encompasses all living organisms: plants, animals and bacteria. The biosphere includes the outer region of the earth (the lithosphere) and the lower region of the atmosphere (the troposphere).
What is the entire system of living organisms and their habitats called?
Ecosystem
Ecosystem: An ecosystem is made up of both the community of organisms in an area and their abiotic surroundings. The Amazon rain forest-including all the plants, animals, and abiotic factors such as sunlight, water, soil and rocks-is an example of an ecosystem.
What is the study of habitats called?
Ecology is the study of organisms and how they interact with the environment around them. An ecologist studies the relationship between living things and their habitats.
What is a habitat called?
A habitat is the natural home or environment of a plant, animal, or other organism. It provides the organisms that live there with food, water, shelter and space to survive. Habitats consist of both biotic and abiotic factors. Biotic factors are living things. On the other hand, abiotic factors are nonliving things.

Where does most of the ocean life live?
Most ocean life can be found in coastal habitats on the continental shelf, even if this area occupies only 7% of the total ocean area. Most of the open ocean habitats are found in the deep ocean beyond the edge of the continental shelf. Ocean and coastal habitats can be created by species living in them.
What are the major habitats in the world?
Land Biomes: The World’s Major Habitats 1 Rain Forests. Tropical rainforests are characterized by dense vegetation, 2 Savannas. Savannas are open grasslands with very few trees. 3 Deserts. Deserts are typically dry areas that experience extremely small amounts of rainfall. 4 Chaparrals. Chaparrals, found in coastline regions,
Which is the richest habitat in the world?
These green, lush forests grow near the Equator (an imaginary line around the middle of the Earth). They are the richest of all biomes, home to more kinds of animals and plants than any other habitat. Amazon rain forest › Hot desert › Deserts are dry places where little plant life can grow.
What makes up the majority of living things on Earth?
In every habitat on earth constant chemical cycles are taking place, as chemicals are transferred from one organism to another. Out of the 25 elements that are critical to the making of living organisms, only four (hydrogen, oxygen, nitrogen and carbon) make up the bulk of all living things.
