| Term | Definition | Hint |
|---|---|---|
| Photosynthesis | The process by which plants,algae, and some bacteria use sunlight, Carbon Dioxide, and water to produce carbohydrates and oxygen | Process requires sunlight |
| Producer | An organism that can make organic molecules from inorganic molecules; a photosynthetic or chemosnythetic autotroph that serves as the basic food source in an ecosystem | The maker |
| Consumers | An organism that eats other organisms or organic matter instead of producing its own nutrition or obtaining nutrients from inoganic sources. | The eater |
| Decomposers | An organism that feeds by breaking down organic matter from dead orgaisms; examples include bacteria and fungi | Break it down |
| Cellular Respiration | The process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide. | respiration=produce water |
| Food Chain | The pathway of energy transfer through various stages as a result of the feeding patters of a series of organisms | plant>Animal link |
| Food Web | A diagram that shows the feeding relationships between organisms in an ecosystem. | Algae>krill dependence from the smallest |
| Trophic levels | Each step through which enegy is transferred in a food chain is known as a trophic level. | producer>consumer |
| Carbon Cycle | Is a process by which caron is cycked between the atmosphere, land, water, and organisms. | Evaporation |
| Nitrogen- fixing bacteria | Only known organisms that can fix atmospheric nitrogen into chemical compounds are a few species if bacteria kwnown as nitrge fixing bacteria. | fix chemical |
| Nitrogen Cycle | A process in which nitrogen is cycled between the atmospere, bacteria, and other organisms | nitrogen transferred |
| Phosphorus cycle | Is the movement of phosphorus from the enviornment to organisms and then back to the enviorment. | phosphorus transferred |
| Ecological Succession | A gradual process of change and replacemnt of some or all of the species in a community | change of animals |
| Primary Successon | Is the type of succession that occurs on a surface where no ecosystem existed before, such as on rocks or small dunes | plants grow through sidewalk |
| Secondary Succession | Common type of succession. Occurs on a surface whre an ecosystem has previously existed | forest fire |
| Pioneer Species | The first organisms to colonize any newly available area and begin the process of ecological succession. | first. explore |
