Which of the following levels of biological organization is the most inclusive?

Biology is the study of life. Since life is such a broad topic, scientists break it down into several different levels of organization to make it easier to study. These levels start from the smallest unit of life and work up to the largest and most broad category.

TL;DR (Too Long; Didn't Read)

The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.

Molecule

Molecules are made of atoms, the smallest unit of chemical elements. They can be found in all matter, living and non-living. Molecules make up the most basic structures of living beings. Two biological disciplines that focus on this level are biochemistry and molecular biology.

Cell

A cell is the basic unit of life. There are two kinds of cells: plant cells, which have a rigid cell wall made of cellulose molecules, and animal cells, which have flexible cell membranes. Cell biologists consider questions such as metabolism and other questions about structure and function within and between cells.

Tissue

Tissue is made of cells that work together to perform a certain task. Muscle tissue, connective tissue, and neural tissue are some types of tissue. Histologists are an example of biologists who work at this level.

Organ

An organ is a system of tissues that work together on a larger scale to do certain jobs within an animal's body. Examples of organs are the brain, heart and lungs. Anatomy is an example of a biology specialty concerned with this level.

Organ System

An organ system is a group of organs that work together to perform specific bodily functions. The respiratory system, for example, uses the lungs, airways and respiratory muscles to inhale oxygen and release carbon dioxide in animals. Physiologists study the function of parts of the body as they work together. Though physiologists can work at any level of biological organization, they often answer questions related to organ systems.

Organism

An organism is a recognizable, self-contained individual. Organisms can be unicellular organisms such as bacteria or amoebae, or multi-cellular organisms comprised of organs and organ systems. A human being is an example of a multi-cellular organism.

Population

A population is a group of multiple organisms of the same species within a specific area. For example, a pride of lions in Kenya, Africa, is a population.

Community

A community consists of all the different species within a certain area. The population of lions in Kenya, plus the populations of gazelles, giraffes, elephants, dung beetles, and all other species in that area, add up to a community.

Ecosystem

An ecosystem is made up of all the communities in a certain area, as well as all the non-living, physical components of the environment. Rocks, water and dirt are a part of an ecosystem. Ecologists may study populations, communities, or whole ecosystems.

Biosphere

The biosphere is all of the ecosystems on Earth added together. Every animal, plant, bacteria, rock, and molecule is a part of the Earth's biosphere. Non-biologists, such as meteorologists and geologists, may join biologists to answer questions at this level of biology organization.

hi in this question. It has given that certain levels of biological organization. And we have to arrange that levels from the smallest level to the largest level. And the terms which are given near earth organ issue sell organ system and the organism. There are several levels in biological organization. And now we are going to arrange it within the given terms among the given cell is the simplest level. Cell is the the simplest level because it is the basic structural unit of all living forms. And when these cells are grouped together and performing a function in the body, then they are called as tissues which means a group of since which are performing a function and will be structurally similar. And when these tissues are grouped together they are called organ. For example, several types of tissues will work together in order to perform a function. Group of issues will perform for for me a specific function in the body. For example, hard, longer liver, kidney etcetera or examples of argon then comes organ system. Organ system is the next level. This organ system is nothing but the group of organs group of organs, which means for example cardiovascular system, the ideal vascular system which consists of organs like heart on the blood vessels and the other organs. And they constitute cardiovascular system Here so many organs are involved and they are performing a one specific function in the body. And this is called an organ system. Next to organ system comes the GST level which is organism which is organism, organism is complex in nature. And these organisms have different organ systems, which means they are multi cellular in nature. They are multi cellular in nature and therefore the correct order from the simplest to the largest, say, issue Oregon organ system. Then, finally, organism. Here, cell is the simplest level, which means at least include the level an organism is the largest complex level. I hope you found this answer useful. Thank you.
