Organization Levels

Make up the most basic level of organization in living systems. Atom
Molecules made by living systems Biomolecule
A biomolecule made entirely of carbon,hydrogen, and oxygen with a 2:1 ratio of hydrogen to oxygen. Carbohydrates
Diverse hydrophobic biomolecules containing carbon, hydrogen, and oxygen Lipids
Reacts to stimuli and transmits signals throughout the body Nervous tissue
Specialized to contract and allow for movement of the body and its parts Muscular tissue
Lines the surface of organs and the body cavities Epithelial Tissue
The most widespread tissue in the body and is specialized to connect and support other tissues; connective tissue ranges from bones, to blood, to fat tissue Connective Tissue
What is the order of the levels of organization Atom->molecule->cell->tissue->organ->organ system-> organism
Are atoms and molecules living or nonliving nonliving
Group of organisms of the same species living in the same area Population
Groups of interacting populations Community
Both living and nonliving organisms interacting Ecosystem
What are the main types of biomes Marine, Freshwater, Desert, Forest, Grassland, Tundra
Areas of salty water, such as the ocean. Make up approximately 75% of Earth's surface. Algae and Plankton communities dominate these ecosystems as the basis of the food chain Marine
Biomes such as lakes and streams, are areas of water that have low salt concentrations. Dominant plant varies based on location Freshwater
Characterized by low levels of rainfall and low population densities. Dominant plant is cacti and drought tolerant plants. Desert
Dominated by trees. Sufficient rainfall. Forest
Dominated by grasses, do not have sufficient rainfall. Grassland
Temperature is very cold, arctic or alpine, tall mountain regions. Sparsely populated. Dominated byy shrubs, low-lying grasses, and smaller vegetation. Tundra
What are human effects on the biosphere Population size, consumption, and technology
As human population increases we require more resources, this leaves fewer resources. Population size
Humans use so many resources that they are getting to be fewer and fewer Consumption
Technologies, such as some that produce pollutants have a negative effect on our ecosystem. Technology
Smallest unit of most compounds that displays all the properties of that compound. Molecule
Specialized structure that performs important cellular functions within a cell. Organelle
Basic unit of all forms of life. cell
Group of similar cells that perform a particular function. tissue
Group of tissues that work together to perform a specific function oragan
Group of organs that work together to perform a specific function. oragan system
Group of organ systems that work together to perform a specific function. an individual animal, plant, or single-celled life form. oragnism
Part of Earth in which life exists including land, water, and air or atmosphere. biosphere
