5 types of symbiotic relationships (Parasitism-Commensalism)

Terms in this set (13)

PowerPoint slide #1 (Parasitism)
1. Disclaimer: This type of symbiolitic relationship is not good & Side Note: If u don't like parasites, don't check this type of symbiotic relationship.
2. Feeds off a host, can harm you.
3. Phobia of parasites is Parasitophobia.
4. Flu virus, tapeworm, flea, tick.
5. One species is HARMED (not killed) while the other species BENEFITS from the relationship.
6. An individual of 1 species (the parasite) feeds on an individual of another species (the host).
7. Parasites can be generalists or specialists (by the host they call home).
8. Parasites that are generalists last longer (from the different host species they have).
PowerPoint slide #2 (Parasitism)
1. Unlike predators (who kill their prey) parasites don't usually kill their host.
PowerPoint slide #3 (Parasitism)
1. Ectoparasites- Are parasites that lives on the outside.
PowerPoint slide #4 (Parasitism)
1. Endoparasites- Are parasites that live inside of a host.
2. Me/a lot of people: vomits into a lunch bag.
3. Fish can get tapeworms.
4. Dog/Cat tapeworms can live in humans.
5. Fish tape worms can not live in humans.
PowerPoint slide #5 (Parasitism)
1. We have our immune system (final episodes of Crash Course Anatomy & Physiology) to protect us from threats.
2. Parasites drive evolution.
PowerPoint slide #6 (Competition)
1. Competition happens when specie seed the same things (when their niches overlap, when 2 or more species need to make use of the same resources).
2. Competition happens between closely related species who have similar needs.
3. The 2 squirrels in the slide is the Fox Squirrel & Gray Squirrel (black, reddish,gray).
PowerPoint slide #7 (Competition)
1. Competition changed community ecology.
2. Some species may not be able to compete for resources & may gradually die out.
3. Change the face of communities: competition,parasites.
PowerPoint slide #8 (Competition)
1. When 1 species goes extinct or "voted off of they island".
2. The better adapted species wins.
3. Don't be a generalist & you might go extinct!
4. Species may change over time to reduce the competition exclusion risk.
PowerPoint slide #9 (Competition)
1. Species may change over many generations (evolve) to use different available recourses, this means less competition for those involved.
2. Everybody wins a little bit!
PowerPoint slide #10 (Mutualism)
1. Cooperative relationships where both species benefit.
2. Bees & flowering plants- Bees get pollen for food; plants gets pollen spread to other flowers to make seeds.
3. Ants & aphids- Ants protect aphids from predators, aphids allow ants to 'milk' them for sugar syrup they produce.
4. Some mutualistic relationships are so close that if 1 species disappears, so does the other!
5. Most classic example is flowers & bees.
6. In a few months here in Ohio the pine trees will release their pollen (TREE SPERM) & cover everything & this is no joke (~April or June)!
7. CCD (Colony Collapse Disorder) is happening & it won't end good for us & if all bees go extinct it would cause massive famines.
PowerPoint slide #11 (Mutualism)
1. When similar species live side & each use part if the resource.
2. 5 species of warblers.
3. Mention in a episode of Crash Course Ecology on YouTube.
4. The warblers beaks looks to same.
5. 2 warblers in the slide is the Cape Ann Warbler (Cape Ann is the name of a game in the Ultimate Driving Universe series in Roblox) & Bay Breasted Warbler.
PowerPoint slide #12 (Commensalism)
1. Relationships where one species benefits, the is not harmed.
2. Vultures & lions- Lions kill & their prey, when they are done vultures come pick the bones clean & vultures benefit, lions are not harmed.
3. (Some commensal relationships may be mutualistic, but benefits to other species have not been identified yet).
PowerPoint slide #13 (Commensalism)
