Living Things and Their Environment
Environment: All living and nonliving things with which an organism may interact.
All of the living and nonliving things in an environment are interconnected.
Ecosystems Ecosystems: All the
living and nonliving things in a given area that interact with one another
Community The living part of
the ecosystem.
Population A group of
organisms of the same type, or species, living together in the same area.
Habitats The place where an
organism lives. It should provide food, shelter and all other resources an organism needs to survive.
Energy Roles Producers Consumers Decomposers
Producers The source of all the
food in an ecosystem. Any organism that goes through photosynthesis.
ConsumersAn organism
that feeds directly or indirectly on producers.
DecomposersBreak down
dead organisms into simpler substances.
Food Chains
A series of events in which food and energy are transferred from one organism in an ecosystem to another. The first link is always a producer.
Food Web Many
overlapping Food Chains
Competition
When there are not enough resources to go around, organisms must struggle with one another to get what they need to survive.
Predation When one organism
hunts another. Predator: The
organisms that hunt. Prey: The organism
that is eaten by the predator.
Predation When one organism
hunts another. Predator: The
organisms that hunt. Prey: The organism
that is eaten by the predator.
Symbiosis A close
relationship between two organisms in which one organism lives near, on or inside of another organism. One will benefit.
Types of Symbiosis Commensalism Mutualism Parasitism
Adaptation A change that increases an organism’s
chance of survival. Types: Adapting to predators Adapting to competition. Adapting to symbiosis
