Term
| A population is "density-dependent" when it is affected by its size. An example might be population growth: as a population gets large, it might grow slower since there are less resources to use up or diseases become prevalent |

|
|
Term
| A population pyramid, also called an age pyramid or age picture diagram, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing. |

Definition
| What does a triangular pattern indicate in terms of population grown |
|
|
Term
| The feeding level of one or more populations in a food web. |
|
Definition
|
|
Term
| Only 10% of energy is stored when an organism from one level of the Pyramid of Energy is eaten by an organism from one level above. |
|
Definition
|
|
Term
| Carbon moves from the environment into the bodies of living things and back into the environment. Carbon dioxide is used to produce sugars and other organic molecules |
|
Definition
| Understand the basic components of the carbon cycle. |
|
|
Term
| The number and variety of all living things in a given area. Includes genetic diversity, species diversity, and ecological diversity. |
|
Definition
|
|
Term
| Population, carrying capacity, pollution, climate change, exotic species, over-harvesting or exploring |
|
Definition
| What are the factors that influence biodiversity? |
|
|
Term
| The state or process of a species, family, or larger group being or becoming extinct. |
|
Definition
|
|
Term
| Background extiction is apparent over long periods of time, some exsiting species become extinct while new species appear through revolution and mass extinction is thought to happen when ther is a relatively sudden change to the Earths ecosystems , making them both unsustainable and unsustaining |
|
Definition
| What is the difference between mass extinction and background extinction? |
|
|
Term
| A measure of the amount of carbon dioxide that enters the atmosphere due to the activities of a person that enters the atmosphere due to the activities of a person or population |
|
Definition
| What is a carbon footprint? |
|
|
Term
| A process in which greenhouse gases rap heat in the atmosphere. |
|
Definition
| What is the greenhouse effect? What gases influence this? |
|
|
Term
| Carbon dioxide, Methane, Nitrous oxide, Hydrofluorocarbons, perfluorocarbons, hexafluoride |
|
Definition
| What are the two major factors influencing the increased amount of CO2 in the atmosphere? |
|
|
Term
| A long-term increase in atmospheric temperatures caused by a buildup of carbon dioxide and other greenhouse gases in the atmosphere |
|
Definition
|
|
Term
| Arctic amplification. Since the difference in temperature between the Arctic and the mid-latitudes helps drive the jet stream (which, in turn, drives most US weather patterns), if that temperature difference decreases, it stands to reason that the jet stream’s winds will slow down. Creates more sluggish weather patterns. |
|
Definition
| Europe had a particularly cold winter last year. Why is that a poor argument that global warming is not occurring? |
|
|
Term
| One theory is that CO2 levels decreased so the ice sheets got larger, and the Earth system had a longer time scale. Detailed information on air temperature and CO2 levels is trapped in these specimens |
|
Definition
| What do ice cores tell us about the historical levels of CO2 in the atmosphere? |
|
|
Term
| Climate change. Melting ice capes, rising sea level. Flooding. Negative effects on human health |
|
Definition
| What are some of the effects of global warming? |
|
|
Term
| Walk, or ride bicycle. Carpool, choose energy -efficient appliances. Minimize heating or coolingn systems. |
|
Definition
| What are some things you can do to reduce your carbon footprint? |
|
|
Term
Immigration- to enter and settle in a foreign place
Emigration- to leave one country or region to settle in another. |
|
Definition
| What is the difference between immigration and emigration? |
|
|
Term
-If birth rates exceed death rates the population increases proportionally.
-If death rates exceed birth rates the population decreases proportionally. |
|
Definition
| How do birth and death rate influence population growth? |
|
|
Term
| Growth whose rate becomes ever more rapid in proportion to the growing total number or size. |
|
Definition
| Exponential Population Growth is: |
|
|
Term
| Population growth that is modulated by the population size relative to carrying capacity. Population growth declines as population approaches carrying capacity, and is negative when population size is greater than carrying capacity. |
|
Definition
| Logistic Population Growth is: |
|
|
Term
| The maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment. Logistic Population Growth |
|
Definition
| What is carrying capacity? Which growth model is impacted by this? |
|
|
Term
| Exert their influences on population size regardless of the population's density.(Weather, food, water, climate) |
|
Definition
| What are some of the density-dependent factors that impact carrying capacity? |
|
|
Term
| The relative number of individuals of each age. |
|
Definition
|
|
Term
| everytime something's eaten only ten percent of the energy make it to the consumer. for example. a peine uses photosynthesis and would be able to use 10% of the energy, then a culo eats the peine and gets 10% of the peine's energy, which is 1% of the original puta's energy. next a blue waffle eats the culo and only gets .1% of the original energy from the puta |
|
Definition
| How does it influence the available energy for each trophic level? |
