Study of interactions among organisms and between organisms and their environment
ECOLOGY
combined portions of the Earth where all life exists....includes land, water and air
BIOSPHERE
group of similar organisms that can breed and produce fertile offspring
SPECIES
Group of individuals of the same species and live in a particular place and at a particular time
POPULATION
red squirrels in the Cleveland Metroparks from Nov. 2004 to Feb. 2005
EXAMPLE OF A POPULATION
different populations that live together in a defined area
COMMUNITY
red squirrels, grey squirrels, garter snakes, oak trees, fungi and deer in the Metropark Forest in No. Chagrin
EXAMPLE OF A COMMUNITY
A part of a biome in which organisms of a characteristic area interact with all living and nonliving parts of the environment
ECOSYSTEM
pond, Lake Erie, Sonoma Desert, Florida Everglades
EXAMPLES OF ECOSYSTEMS
many populations form this
COMMUNITY
many ecosystems form this
BIOME
many biomes form this
BIOSPHERE
Grooup of ecosystems that have the same climate and dominant communities
BIOME
OBSERVE......
EXPERIMENT....
MODELING....
APPROACHES TO MODERN ECOLOGICAL RESEARCH
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
FLOW OF ENERGY IN AN ECOSYSTEM
Study of interactions among organisms and between organisms and their environment
ECOLOGY

APPROACHES TO MODERN ECOLOGICAL RESEARCH
study of the interactions between living and nonliving things in an environment
ECOLOGY
flow of energy in an ecosystem is passed through this series of steps in which organisms transfer energy by eating and being eaten
FOOD CHAIN
grass <<<< rabbit <<<< fox
EXAMPLE OF A FOOD CHAIN
Algae <<< zooplankton <<< small fish <<< squid <<< shark
EXAMPLE OF FOOD CHAIN
formed when the feeding relationships in an ecosystem form a network of food chains
FOOD WEB
each step in a food chain or web
TROPHIC LEVEL
trophic levle of producers
FIRST TROPHIC LEVEL
trophic level of herbivores
SECOND TROPHIC LEVEL
trophic level of omnivores and or carnivores
THIRD TROPHIC LEVEL
diagram that shows the relative amounts of energy or matter contained within each trophic level in a food chain or web
ECOLOGICAL PYRAMID
amount of energy available within a trophic level that can be passed on to the next level
10 PERCENT
total amount of living tissue in a given trophic level .... expressed in grams of organic matter per unit area
BIOMASS
shows the relative numbers of individual organisms at each trophic level
PYRAMID OF NUMBERS
energy..... biomass
