|
|
Predator |
An animal that naturally preys on others. |
|
|
Prey |
An animal that is hunted or killed by another for food. |
|
|
Commensalism |
A relationship between in which one organism benefits and the other organism is neither helped nor harmed. |
|
|
Mutualism |
The relationship between two or more organisms that live closely together and benefit from each other. |
|
|
Describe why difference between a habitat and a niche. |
A habitat is where the organism lives. A niche is the role or position that an organism had in its environment. |
|
|
What's an invasive species? What is a native species? |
Invasive species are either intentionally or unintentionally transported to a new habit.
Native species are found only in a particular region or indigenous (found both within the region and elsewhere.) |
|
|
What is a decomposers role in a food web? |
Decomposers decompose dead animals bodies. (To make or become rotten; decay) |
|
|
How can the removal of one organism in a food web affect the others? Explain. |
The organism wouldn't be able to pass off the energy, the food chain will be destroyed and the animals will die of starvation. |
|
|
Where is the most energy found in the food chain, web, and ecological pyramid? |
Food chain/web-Autotroph
Ecological pyramid-Producers |
|
|
Using the ecological pyramid, where were the least amount of organisms usually found? |
The secondary carnivores/tertiary consumer. |
|
|

1. Organism 2. Population 3. Community 4. Ecosystem |
|
|
Explain the difference between primary and secondary succession. |
1. Primary succession begins in an area where no soil is present.
2. Secondary succession occurs in areas where soil is present. |
|
|
Competition |

|
|

An animal or plant species becomes fitted to its environment. |
|
|
Climax community |
A stable mature community in a successive series which has reached equilibrium after having evolved through stages and adapted to its environment. |
|
|
Pioneer species |
Are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain o ecological succession that ultimately leads to more biodiverse steady-state ecosystem. |
|
|
Abiotic |
A non living condition or thing, as climate or habitat, that influences or affects the ecosystem and the organisms in it. |
|
|
Biotic |
A living thing, as an animal or plant, that influences or affects an ecosystem. |
|
|
