Watson-2 Ecosystem Project Biotic Factors Living factors that affect the ecosystem Predator Organism that eats other another organism LEVELS OF ORGANIZATION Organism- A specific species of a living thing in an area. Parasitism Relationship between 2 organisms where one benefits while the other is harmed EX: Badger, Tuberculosis,
Shiitake, Lilium Platyphyllum Abiotic Factors Non-living factors that affect an ecosystem EX: Wind patterns,
Sunlight, Rain,
Temperature Population- A group of organisms that
mate with one another and live in the
same place and time. Community- Populations that interact with each other. Ecosystem- Several types of communities that interact between themselves and abiotic factors. Host Organism being harmed in a parasitism relationship. Ex 1: Tapeworms attach themselves inside of their hosts intestine and eat at the host's partly digested food and deprive the host of nutrients Ex 2: Baranacles attach themselves to the body of a whale. Although they don't cause serious damage, they are itchy and annoying Ex 3: Aphids accumulate on plants and eat the sap on their hosts. Organism eaten by predator Fox and Rabbit Koala and Eucalyptus Otter and Trout The Sun! The source of all energy: Parts of the food chain Producer Organisms that produce their own food. (Plants) Consumer Organisms that can't produce their own food, so they must consume producers. (Animals) Decomposer Organisms that eat decaying matter and release the nutrients and minerals back into the soil. (Batcteria and Fungi) Food Chain A food chain is the linear flow of energy through an ecosystem. The arrows in a food chain represent the flow of energy. 3 Types of Consumers Primary Consumer
Secondary Consumer
Tertiary Consumer Primary Consumer A Primary Consumer is an herbivore such as a Lemming Secondary Consumer A Secondary Consumer eats primary consumers. An example would be an ermine. Tertiary Consumer A Tertiary Consumer, such as the dingo, eats Secondary Consumers. The lemming is only a primary consumer as it only eats plants such as moss and grass An ermine is a secondary consumer because it eats herbivores such as mice, squirrels, and rabbits, but also a primary consumer since it also eats berries Dingos are tertiary consumers because they eat wallabies, but are also secondary since they eat primary consumers such as mice and rabbits. Producer:

Mushroom Sun Water EX: a bunny Prey Food Web A series of interwoven food chains Food Web: -Shows how plants and animals are interconnected by different paths -Follow a single path as organisms eat each other Food Chain: FOOD WEBS: The Fox eats the Rabbit The Otter eats the Trout The Koala eats the Eucalyptus leaves Killer Whale

Producer Freshwater Ex: a nest of bunnies Ex: A forest Organisms may compete for abiotic factors such as nesting grounds, sunlight, or soil. Terrestrial Grizzly Bear
Secondary Consumer Marmot
Primary Consumer Hawk
Secondary Consumer Berries
Producer Deer
Primary Consumer Swallowtail
Primary Consumer Fungus
Decomposer Grass
Producer Grouse
Primary Consumer Impact on Food Webs Global warming and carbon dioxide emmisions created by humans are possibly causing the phytoplankton population to decline. If phytoplankton were to disappear , then it would cause the entire marine/saltwater food web to collapse. "Inside Yellowstone - Glossary of Terms." National Park Service. NPS, n.d.

There are also other types of symbiotic relationships such as commensalism and mutualism. Commensalism Commensalism benefits one partner and doesn't effect the other. Mutualism Mutualism benefits both organisms. Unlike a parasitic realationship where one organism benefits and the other suffers, a predator/prey relationship is more healthy. Because the predator will usually aim for weak, sick, or elderly prey, the prey's species will be stronger over all. Marine/Saltwater ecosystems can be found in oceans Freshwater Ecosystems can be found in ponds, marshes, swamps, as well as some lakes This ecosystem could be found in a Deciduous Forest. A similar food web could also be found in a coniferous forest. Food chain Conclusion This prezi displays our knowledge on food chains, food webs, and the individual pieces of the ecosystems that we have learned over the few days that we were given to work with.
