organization
Answers
Answer:
Here is your answer:
The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs,organ systems, organisms, populations, communities, ecosystem, and biosphere.
Answer: There are 13 levels of organization. In sequence, they are represented as atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, population, community, ecosystem, biome, and biosphere
Explanation:
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.
THE CELL
The cell is known to be the basic building block of life. It performs various metabolic functions like providing structure and rigidity to the body, converting food into nutrients and energy, and others. While it is apparently not the smallest particle (organelles, molecules, and atoms are even smaller in size), the cell is called as such because it is the smallest living entity that can function on its own. At cellular level, organisms can be classified into two: single-celled organisms (unicellular) and multiple-celled organisms (multi-cellular).
TISSUE
When similar cells aggregate, they form a tissue. Basically, a tissue is a group of interconnected cells that perform the same function. Like cells, tissues perform metabolic processes that keep the organism alive. In multi cellular organisms, the study of tissue is called histology.
ORGAN
Coming from the Latin word organum which means “tool” or “instrument”, an organ is a collection of tissues and similar structures that all function as one. Organs of multi-cellular organisms are in fact very diverse. In plants, their organs include the flowers (if there is) roots, stems, and the leaves. On the other hand, organs of animals include the brain, heart, stomach, eyes, and many more.
ORGANISM
An organism can be simply defined as any living thing that is composed of various organ systems that function altogether. By far, about 8.7 million organisms are estimated by scientists but only 1.2 million of that have been identified. Hence, various efforts have been continually done in order to discover them.
POPULATION
When similar organisms group together, they form the next level in the organization, a population. By definition, a population is formed when such individuals reside a common environment at a given time. For instance, a population can change over time due to several events like births, mortality, and migration of organisms. Oftentimes, the number of individuals in a population is highly dependent on the abundance of resources and the presence of favorable climate. In addition, predation and competition are also biological factors that control populations.
COMMUNITY
Next to the hierarchy is the community. A community is defined as the interactions of different populations with each other. Apparently, various interactions can exist such as mutualism, commensalism, predation, parasitism, and competition. Oftentimes, a certain population of organisms tend to dominate the community and hence are relatively more abundant than others. Such is considered as a distinguishable characteristic of a biological community.
ECOSYSTEM
A short term for “ecological system”, an ecosystem is the interaction of (organisms, population, and community) to their abiotic or non-living environment. The biotic (living) members of an ecosystem are highly dependent on such abiotic factors which include the weather, sunlight, water depth, salinity, and the availability of nutrients. Hence, the presence or absence of even one factor can greatly affect the ecosystem. In addition to that, one distinct characteristic of an ecosystem is that each organism has a “niche” or role to perform.
