Cylces And Biodiveristy Flashcards
Biotic
Living things, organisms
Plants, bacteria, animals
Abiotic
Non-living things, physical features
Clouds, ocean, mountains
Dynamic
Anything that is undergoing constant change
System
Any object or process that is made up of different kinds of parts that have influence on one another.
Geosphere
The solid, physical earth
Hydrosphere
Rivers,lakes,ocean anything with water
Biosphere
All living things; process could take seconds to millions of years
Atmosphere
The envelopes of air that surround the planet
Cycle
The constant movement of matter and energy through a set of reoccurring changes
4- steps in the water cycle
Evaporation
Condensation
Precipitation
Collection
Evaporation
Turning into vapor and held in the atmosphere
Condensation
Cold temperature, pulling moisture out of the air
Precipitation
Rain sleet hail any water form
Collection
Water accumulates on. Lakes rivers ocean soil etc
Biology
Study of life
DNA
(Deoxyribo-nucleic acid) universal genetic code of all living things
Cell
The smallest unit considered fully alive, all contain DNA
Sexual Reproduction
Cells from two parents parents unite to form the first cell of a new individual
Asexual reproduction
A single organism produces off spring identical to itself
Homeostasis
A condition of maintaining a stable internal environment (cells,organism)
Metabolism
The chemical reactions through which an organism breaks down materials
Macromolecules
Carbohydrates
Lipids (fat)
Protein
Carbs
Compounds made up of carbon, hydrogen, and oxygen can be simple or complex
Simple carb
1 or 2 sugar molecules
Complex carb
Having many sugar molecules
Lipids
Compounds made of carbon and hydrogen, can store energy and are not soluble in water
Protein
Compounds made up of carbon, hydrogen, oxygen and nitrogen, made of the small molecules called amino acids, perform many cell functions
Enzyme
A protein that is a catalyst or speeds up chemical reactions in cells
Polarity
When the charges on a molecule are unevenly distributed, resulting in poles
Hydrogen bond
The attraction and resulting bond between a hydrogen atom + and an oxygen atom - on diff. Water molecules
Cohesion
The attraction between molecules of the same substance
Adhesion
The attraction between molecules of diff. substances
Phylogeny
The study of how living and extinct organisms are related to one another
List of categories
Least specific- Domain Kingdom Phylum Class Order Family Genus Most specific- Species
The three domains of life
Archaea, Bacteria, Eukarya
Eukarya Kingdom
Protist, Fungi, Plants, and Animals
Autotroph
A Producer
an organism that is able to capture energy from sunlight
Heterotroph
A Consumer
an organism that contains energy by consuming living things
