Question
Answer
Photosynthesis   Process through wich sunlight makes sugar molecules and oxygen; 6CO(2) + 6H(2)O + Solar Energy -> C(6)H(12)O(6) + 6O(2)  
🗑
Producer   Makes it's own food  
🗑
Autotrophs   Self-Feeders; Producers  
🗑
Consumers   Gets energy from other organisms and indirectly from sunlight  
🗑
Heterotrophs   Other feeders; consumers  
🗑
Carnivores   Flesh eaters  
🗑
Cellular Respiration   Process of breaking down food to create energy. C(6)H(12)O(6) + 6O(2)-> 6CO(2) + 6H(2)O + Energy  
🗑
Heterotrohs   Other feeders  
🗑
Ominvores   Eaters of all  
🗑
Food chain   Sequence of energy transfer from one organism to the next  
🗑
Food Web   Shows many feeding relationships that are possible in an ecosystem  
🗑
Trophic Level   Each step in the transfer of energy through a food chain or food web in an ecosystem  
🗑
Carbon Cycle   Process by which carbon is processed through the atmosphere, land, water and organisms  
🗑
Carbonates   Converted carbon makes up hard parts of bones and shell  
🗑
Carbon sinks   Carbon Reservoirs largest is limestone  
🗑
Fossil Fuels   Deposits of coal, oil, and natural gasfrom plants and animals that died millions of years ago  
🗑
Nitrogen-Fixing Bacteria   Organisms that can take transform Nitrogen into a useable form for plants  
🗑
Nirtogen Cycle   Process in which nitrogen is transformed between atmosphere, bacteria and other organisms.  
🗑
Legumes   Has nodules on roots from Nitrogen fixing bacteria on roots. Peas, beans and clovers  
🗑
Proteins   Used to build new cells.  
🗑
Phosphorus cycle   Movement of phosphorus from environment to organisms and then back to environment  
🗑
Algal bloom   Excess nitrogen and phosphorus in an aquatic ecosystem or nearby waterway can cause rapid and over abundant growth of algae.  
🗑
Ecological Succession   Gradual process of change and replacement of the types of species in a community  
🗑
Primary Succession   Occurs on surfaces where NO ecosystem existed before  
🗑
Secondary Succession   More common, occurs in ecosystems where life existed before it has been disturbed or disrutped by humans, animals or natrual disasters  
🗑
Pioneer Species   First organisms to colonize any newly available area and begin the process of ecological succession  
🗑
Climax Community   When community is final and stable  
🗑
Old Field Succession   Another type of secondary succesion occurs on abandoned farmland  
🗑
Lichens   A pioneer species that is colorful, flaky and seen on bare rocks and trees  
🗑
Bacteria   A pioneer species and that helps break down organisms  
🗑
Decomposer   Consumers that get food by breaking down dead organisms such as bacteria and fungi. They allow nutrients in rotting material to return to the soil, water, and air  
🗑
Carbohydrates   Sugar Molecules  
🗑
