Cooperation-
A social behavior in which a group of organisms work collectively to achieve a common benefit
Decomposer-

Ecosystem-
The network of both animate and inanimate objects which are interdependent on each other
Food Web-
the relationship between all of the predators and prey in an ecosystem
Herbivore-
An animal that eats only plants for food
Niche-
the specific role that each organism in a balanced preforms, such as primary consumer, or top predator
Omnivore-
An animal that eats both plants and other animals for food
Parasite-
An organism that feeds off of another organism
Photosynthesis-
The process through which plants use chlorophyll to turn water carbon dioxide and sunlight into glucose or sugar
Phytoplankton-
Microorganisms that live in the ocean
Predator-

Prey-
An animal that is preyed upon by other animals for food
Producer-
The primary food source which converts sunlight or other forms of energy into food for other organisms
Respiration-
The process by which an organism derives energy from its food; cellular respiration
Socialization-
The formation of social groups of animals in order to increase any individual's chance of survival
Symbiosis-
A relationship between two animals that benefits at least one organism
Types of Biomes
The Arctic: A freezing cold habitat where there are diverse creatures trying to survive the cold (even on the hotter days it's below freezing.
The Ocean: The ocean has the most diverse sea creatures home to fish sharks whales and much much more. It is also the largest of ecosystems.
Rain forest: A wet humid place filled with lots of trees and plant life as well as animals

The River: The river is one of the most calm yet dangerous ecosystems. It has many diverse creatures that wait and strike at the right moment.
Food Webs
Savannah
Arctic
Coral reef
Groups of Animals
Cooperation
Symbiosis
Socialization
Socialization
Food web-
a diagram that shows which animals prey upon which in a specific ecosystem
Food chain-
a diagram that shows only one series of links in a food web
When animals work together to achieve a common goal, such as catching food
When two other organisms interact in which at least one specias benefits
Symbiotic Relationships
-Commensalism - When one organism benefits a when nothing happens to the other
-Parasitism - When one organism benefits and tho other is harmed
-Mutual ism - When both organisms benefit
When animals form social groups. Social groups always have some form of hierarchy. They are formed to help catch food and for protection
