  1. Relationships In Ecology. Biological Community Intra-specific Competition Intra-specific Cooperation Inter-specific relationships: Competition Browsing/Grazing Predation and Scavenging Commensalism Mutualism (symbiosis) Parasitism (ecto and endoparasites) Saprophytism Antibiosis http://www.hickerphoto.com/data/media/166/tundra-animals_523.jpg

  2. Biological Community. • A population that all live and interact in the same area is a biological community. http://www.mass.gov/envir/forest/images/multiLayerForest.jpg

  3. Intra-specific Competition. • Intra-specific competition is competition between individuals of the same species for essential resources. • For example these two Deer are both from the same species but still compete for mating rights and territory. http://farm3.static.flickr.com/2150/1523863979_5235218b54.jpg?v=0

  4. Intra-specific Cooperation • Intra-specific competition is when individual organisms help each other for survival and reproduction. • An example of this is when animals join together in herds and groups and work together to obtain food, avoid enemies and watch out for each other. http://www.desktopscenes.com/Scenes%20from%20the%20National%20Bison%20Range%20(2004)/Bison%20Herd%20on%20the%20Move.jpg

  5. Competition. • Competiton is when organisms in the same ecosystem go against each other for the same resources. • For example when lions fight against vultures to keep their kill. http://picasaweb.google.com/janicetipping/MasaiMaraKenya/photo#5186417424285934258

  6. Browsing/Grazing • Browsing and grazing is the predation of herbivores after vegetation. • For example Rhinoceros graze the Savannahs of Africa for grass. http://www.arkive.org/media/45C07EF6-9B43-405D-9A39-4F112BEB841C/Presentation.Medium/Sumatran-rhinoceros-grazing.jpg

  7. Predation. • Predation is the relationship of an animal hunting and feeding on another known as their prey. • For example this Hawk feeding on a vole that it has hunted.

  8. Scavenging • Animals rely on other animals kills for food. Carnivorous but don’t hunt for themselves. • For example Hyenas roam in packs and chase the hunter away from its prey so that they can feed http://www.perlgurl.org/archives/blogpics/AfricaFieldNotes/WebHyena02.jpg

  9. Commensalism • A relationship between two organisms where one benefits and the other is neither helped nor harmed • For example a bird that nests in a tree does not harm the tree but benefits from it. http://farm1.static.flickr.com/168/474785895_3bf12968f4.jpg?v=0

  10. Mutualism (Symbiosis) • Mutualism is a relationship between organisms where both benefit. • For example this Wood Pigeon (Kereru) feeds on the fruit of Puriri trees and when it excretes it spreads the trees seeds. http://www.pacifictreasures.co.nz/site/covenant/images/FEB06_3_031_1_3.jpg

  11. Parasitism • Parasitism is a relationship between two organisms where one benefits and the other is harmed. • For example maggots in a sheep's wool. They feed on the sheep's living flesh causing great pain to the sheep and eventually death. http://www2.dpi.qld.gov.au/images/13368.jpg

  12. Saprophytism • A saprophyte is an animal that gains nutrients from non-living organic matter, usually plant or animal matter. • For example a dung beetle using animal manure to incubate and feed is offspring. http://www.naturephoto-cz.com/photos/mraz/dung-beetle-05a26002.jpg

  13. Antibiosis • Antibiosis is a relationship between two organisms that is detrimental to at least one of them. • For example birds and snakes in the Amazon try to feed on Poison Arrow Frogs but are poisoned in the process. http://zims.isis.org/aark/YOTF%20Campaign%20Pack%20images/Dendrobates%20auratus,%20Green%20and%20Black%20Poison%20Arrow%20Frog,%20Richard%20Gibson.jpg
