|
|
study of the interactions between living and nonliving things in an environment
|
ECOLOGY
|
|
|
MAIN SOURCE OF ENERGY FOR LIFE ON EARTH
|
SUN
|
|
|
organisms that use energy from the environment to make new living tissues and therefore MAKE THEIR OWN FOOD
|
AUTOTROPHS
|
|
|
organisms that are key to the flow of energy through the biosphere
|
PRODUCERS
|
|
|
green plants, organisms with the green pigment of chlorophyll
|
EXAMPLES OF PRODUCERS
|
|
|
chemical process performed by AUTOTROPHS in which sunlight, carbon dioxide and water are used to form sugar and oxygen
|
PHOTOSYNTHESIS
|
|
|
process that occurs in autotrophs without sunlight .... make own food without light ( use chemicals instead)
|
CHEMOSYNTHESIS
|
|
|
Organisms that rely on other organisms for their energy and food supply
|
HETEROTROPHS
|
|
|
organisms that eat other organisms
|
CONSUMERS
|
|
|
herbivores....
carnivores.... omnivores... detritivores.... decomposers |
EXAMPLES OF CONSUMERS
|
|
|
organisms that eat plants
|
HERBIVORES
|
|
|
organisms that eat only other animals
|
CARNIVORES
|
|
|
organisms that eat both plants and animals
|
OMNIVORES
|
|
|
organisms that feed on plant and animal remains.... mites, worms, snails, crabs
|
DETRITIVORES
|
|
|
heterotrophs that break down organic matter
|
DECOMPOSERS
|
|
|
from the Sun or inorganic compounds to autotrophs to heterotrophs..... FLOWS 1 WAY

|
|
|
study of the interactions between living and nonliving things in an environment
|
ECOLOGY
|
