|
Definition
| A biological community is made up of interacting populations in a certain area at a certain time. |
|
|
Term
|
Definition
| An ecosystem is made up of interacting populations in a biological community and the community's abiotic factors. |
|

|
Definition
Terrestrial--located on land
Equatic--located in water fresh and salt |
|
|
Term
|
Definition
| A habitat is the place where an organism lives out its life. |
|
|
Term
|
Definition
| A niche is all strategies and adaptations a species uses in its environment--how it gets food, how it survives, and how it reproduces. |
|
|
Term
|
Definition
| The relationship in which there is a close and permanent association between organisms of different species. |
|

Term
| What is the difference between abiotic and biotic components? |
|
Definition
Biotic factors are the non-living parts of an organism.
Abiotic factors are the living parts that inhabit an environment. |
|
|
Term
| What is the difference between habitat and niche? |
|
Definition
| The habitat is where the organism lives and the niche is the strategies the organism uses in its environment. |
|
|
Term
| What is the difference between community and population? |
|
Definition
| A population is a group of organisms all of the same species, and a community is a group of different species interacting and living in a certain area at the same time. |
|
|
Term
| What is an indirect relationship |
|
Definition
| The predator-prey relationship in an indirect relationship, because they indirectly benefit each other. |
|
|
Term
|
Definition
| An autotroph is a producer organism that uses light energy or energy stored in chemical compounds to make energy rich compounds. |
|
|
Term
|
Definition
| An organism that cannot make its own food and feeds on other organisms. |
|
|
Term
|
Definition
| Organisms such as bacteria and fungi break down and realease nutrients from dead organisms. |
|
|
Term
|
Definition
A simple model that scientists use to show how matter and energy move through an ecosystem.
berries--mice--bears |
|
|
Term
| What is the trophic level? |
|
Definition
| It is a feeding step in the passage of energy and materials. |
|
|
Term
|
Definition
| Energy is the ability to change, organize and use energy to perform biological functions. |
|
|
Term
|
Definition
| yes, a decomposed can recycle energy, as can a plant with manure. |
|
|
Term
|
Definition
| Yes, energy can change form because it has to change to be used and recycled. |
|
|
Term
| How do organisms get energy? |
|
Definition
| Organisms either produce their own energy or they feed on other organisms, or they use light. |
|
|
Term
| Why is it that the amount of energy remaining in the final transfer of a food chain is only a portion of what was available at the first transfer. |
|
Definition
| A portion of the energy is given off as heat at each transfer. |
|
|
Term
| Suppose 10,000 Keals of energy are available at the level of a producer. What is the total amount of energy lost by the time energy reaches a first-order consumer? Second-order consumer, and third-order consumer? |
|
Definition
First-Order consumer 9,000 keals
Second-Order " 900 keals
Third-Order " 90 keals |
|
|
Term
| What is the difference between a food chain and a food web? |
|
Definition
| A food chain is a simple word used by scientist to decribe how matter and energy move through an ecosystem, a food web is a model that shows all the possible feding relationships at thech trophic level in the community. |
|
|
Term
|
Definition
| It is the loss of water through the leaves and stromata of a plant. |
|
|
Term
| Which plants lose more water? Rain Forest or Desert? |
|
Definition
| The desert because there is very little rainfall. |
|
|
Term
| What processes lead to an increase of CO2 in the atmosphere? |
|
Definition
| When autotrophs and heterotrophs use carbon-containing molecules and release energy, co2 is released into the atmosphere. |
|
|
Term
| What environmental problems is directly related to an increase in atmosphere co2? |
|
Definition
| Global warming and the changing weather patterns associated with global warming. |
|
|
Term
| How do algae plants and algal protests decrease the amount of co2 in the atmosphere? |
|
Definition
| They use photosynthesis to produce energy and this process decreases co2 in the atmosphere. |
|
|
Term
| Plants can't use the 80% of nitrogen in our atmosphere, where do plants get their nitrogen? |
|
Definition
| Plants use nitrogen in the soil that has been converted into usable form to get their nitrogen. |
|
|
Term
| How are bacteria important to the nitrogen cycle? |
|
Definition
| Certain bacteria converts the nitrogen from the air into a more usable form for the other plants. |
