Cells are the most basic unit of life at the smallest level of organization. Cells can be prokaryotic (without nucleus) or eukaroyotic (with nucleus). The four categories of tissues are connective, muscles, epithelial, and nervous tissues.
What is the lowest level of organization Why?
All living things are organized at different levels. These levels of organization organism include cells, tissues, organs, and organ systems. Cells form tissue, tissues form organs, and organs make up organ systems. The lowest level is the cell.
What are the 5 levels of organization?
These parts are divided into levels of organization. There are five levels: cells, tissue, organs, organ systems, and organisms.
What is the smallest level of organization in ecology?
Organism. It is the lowest level of organization, which includes both unicellular and multicellular organisms. All the living species in this level exhibits all the characteristics required for the existence of life.
What are the levels of organization from smallest to largest?
The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.
What are the 13 levels of organization?
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.
What is the highest level of organization?
The highest level of organization for living things is the biosphere; it encompasses all other levels. 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.
What are the 12 levels of organization?
Levels of organization include atom, molecule, macromolecule, cell, organ, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere.
What level of organization is a vein?
Organ Systems • 6- Cardiovascular system (circulatory) • The cardiovascular system carries food and oxygen to the cells, and carries carbon dioxide away from the cells. Your heart, arteries, veins, and capillaries, are organs in the cardiovascular system.

What are the 5 levels of an ecosystem?
Ecology at many scales. Within the discipline of ecology, researchers work at five broad levels, sometimes discretely and sometimes with overlap: organism, population, community, ecosystem, and biosphere.

What are the 5 levels of ecological hierarchy?
Ecologists generally organize the biological world in a nested hierarchy. Above the level of the individual organism, from the least to most inclusive, the levels of this hierarchy are the population, community, ecosystem, biome, and biosphere.
What are the 7 levels of organization?
