Environmental Survey
Environmental Survey
ECOLOGY The study of the
relationships among organisms in an environment.
ParasitismMutualismCommensalism
Symbioses (relationships among living
things)1. Parasitism –
relationship in which an organism lives in or on another organism and causes harm
Ectoparasite
Endoparasite
2. MutualismA relationship
where both organisms benefit
Mutualism
Clown Fish / Anemone The anemone gets food
particles from the fish leftovers
The fish receives protection from the anemone’s tentacles
The clown fish is unharmed by the toxins in the stinger
Insects / Flowers The insects receive
nectar from the flower The flower uses the
insects to carry pollen to other flowers for reproduction
3. CommensalismA relationship where one organism benefits and the other is unaffected
Commensalism
The whale species / barnacle
The whale is neither helped or harmed
The sedentary barnacle has a place to live and get a variety of food
Tropical Birds/ Army ants
Ant are unaffected by birds following them as they look for food
Other insects that flee from the army ants are quickly eaten by the birds.
Biotic vs. Abiotic
Biotic vs. Abiotic
Vegetation Animals Fungi Bacteria Algae
Rocks Gases Water Hydrocarbons Toxins Sun
Trophisms“How one eats”
Heterotroph (consumer)
Omnivore Carnivore Herbivore
Autotroph (producer)
Decomposer
Feeding relationships among producers, consumers and decomposers
Producers are the foundation
Primary, secondary and tertiary consumers are the body
Decomposers break down organisms that have died.
BIOMASS Amount of
energy that can be passed along among organisms in an ecosystem
Highest with producers, lowest at the top with carnivoreshttp://www.youtube.com/watch?v=TE6wqG4nb3M&featur

Invasive Species“non – native”
Describes a species that has been introduced into an area that does not belong there !!

Upset the balance of the food web in an eco – system
Can cause extinctions of “keystone species”
Result in collapse of food web – destruction of an ecosystem.
