Ecosystems (all of LS-2)

Human population increases impact natural resource consumption on Earth
Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.

Abiotic - a nonliving factor in an environment
Biotic - the living organisms in a given community, including all plant and animal life within the community.
Commensalism - a symbiotic relationship in which one species benefits while the other is not affected.
Competition - A relationship between organisms that strive for the same resources in the same place
Carnivores - eats meat
Consumers - can not make their own food
Decomposers - break down dead plants and animals into component parts, including nutrients

Ecosystem - a biological community of interacting organisms and their physical environment.
Food Chain - sequence of organisms in which each depends on the next, and the lower members are a source of food.
Food Web - interconnected food chains of producer, consumers, and apex predators
Grazers - Feed on living organisms without killing them
Herbivores - eat plants
Intraspecific Competition - competition which occurs between members of the same species
Interspecific Competition - Competition which occurs between members of different species.

Omnivores - eats both plants and meat
Mutualism - A symbiotic relationship in which both species benefit
Parasitism - A symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.
Photosynthesis - using the energy in sunlight to make food
Predator - animals that eat a prey animal
Prey - animals that are hunted and eaten by a predator for food
Producers - living things that use energy to make food.
Scavengers - eat organisms that are already dead
Symbiosis - a close relationship between two species in which at least one species benefits
