| Define Population w/ Example | The number of 1 species in a given area. Humans in a town. |
| Define Producers w/ Example | An autotrophic organism that serves as a source of food for other organisms in a food chain. Plants. |
| Define Consumers w/ Example | Organisms of an ecological food chain which receive energy by consuming other organisms. Tiger. |
| Define Autotrophs w/ Example | Organisms that produce their own energy. Plants |
| Define Heterotrophs w/ Example | Organisms that consume energy from other organisms. Humans |
| Define Species w/ Example | A group of living things based on genetics, ability to reproduce similar organisms, and characteristics. |

| Define Climate | Weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, |
| What is the difference between abiotic and biotic? | Biotic = Living Abiotic = Non Living |
| What do food webs display? | Systems of interlocking and dependent food chains. |
| What are some resources needed for organisms to survive? | Water, Food, Energy, Shelter |
| Define Density Dependent Factor w/ Example | Any factor limiting the size of a population whose effect is dependent on the number of individuals in the population. Disease. |
| Define Density Independent Factor w/ Example | Any factor limiting the size of a population whose effect is not dependent on the number of individuals in the population. Earthquake. |

| Where would a lion fall in a food pyramid? | Predators, Tertiary or Secondary Consumer |
| Define Biodiversity | The variety of life in the world or in a particular habitat or ecosystem. |
| Would a classroom would be a location with high or low biodiversity? | Low |
| Would a farm have high or low biodiversity? | High |
| Define Ecosystem: | All biotic and abiotic factors in an area. |
| Why is biodiversity important? | To maintain a healthy equilibrium for food chains and food webs to thrive. |
| Define Biome: | An area characterized by ecosystems including abiotic and biotic factors |
| Define Flora: | Plants |

| Are Memory Cells a specific or non specific part of the immune system? | Specific |
| What are antibodies? | Proteins that are secreted by B cells that are stimulated by the presence of antigens on invading cells and placed on invading cells and used as a homing device for natural killer cells, macrophages, and T-cells |
| Define homeostasis: | Maintaining a healthy, internal equilibrium. |
| What informs homeostasis? | Negative feedback |
| What is a receptor? | Structure that monitors internal conditions. |
| What is a control center? | Integrates the information fed to it by the receptors. |
