EOG Science Review

network of interconnected food chains – shows how energy moves through an ecosystem; arrows indicate the direction in which energy is transferred from one organism to another

• Consumers
• Food web
• Decomposers
• Pollution

process by which some producers change light energy into chemical energy (use light, carbon dioxide, and water to produce oxygen and glucose)

• Osmosis 
• Photosynthesis
• Respiration
• Anaerobic

positively charged particle present in the nucleus of atoms

• Proton    
• Atomic number
•  Periodic table
• Electron

when deep, cold water rises from the ocean bottom to the ocean surface

• Producers
•  Evolution    
• Plankton
• Upwelling

introduction of harmful waste products, chemicals, not native to environment

• Consumers
• Food web
• Decomposers
• Pollution

type of cells that lacks a nucleus and other organelles

• Antibiotics
• Binary fission   
• Prokaryote
• Protist

organisms that make their own food (plants, plankton)

• Producers
•  Evolution    
• Plankton
• Upwelling

change in organisms over time due to environmental influence or competition

• Producers
•  Evolution    
• Plankton
• Upwelling

close interaction between two or more different species

•  Abiotic
• Community
• Symbiosis
• Matter

tiny organisms that float in ocean currents; most are unicellular and perform photosynthesis
