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
