Ecology |
It is the interactions between organisms and their environment. |
|
|
Biotic |
Living things, their remains, and features such as nests associated with their activities. |
|
|
Plant |
A living thing that grows in earth, in water, or on other plants, usually has a stem, leaves, roots and flowers and gets nutrients by using photosynthesis |
|
|
Animal |
A living organism that feeds on organic matter and has specialized sense organs and nervous system and able to respond rapidly to stimuli |
|
|
Community |
It is an association of populations of two or more different species occupying the same area and in a particular time |
|
|
Omnivore Carnivore Herbivore Scavenger Predator Prey |
Omnivore: An animal that eats both plants and animals Carnivore: Am animal that eats other animals Herbivore: An animal that eats plants or other producers Scavenger: An animal that feeds on the remains of another organism Predator: Is an organism that eats another organism Prey: The prey is the organism that is being eaten by the predator |

The layer of gassed surrounding earth |
|
|
Food web |
A representation of the feeding relationships within a community |
|
|
Food chain |
A sequence of organisms each feeding on the next showing how energy is transferred from one organism to another |
