Relationships within Ecosystems The who, what, where, when, why of it all.

Niche The unique role a species has within an ecosystem. (Dung Beetle) African Dung Beetle - YouTube African Dung Beetle - YouTube

Habitat Where an organism generally lives within an ecosystem. e.com/watch?v=P NgGBemdnuw e.com/watch?v=P NgGBemdnuw

Competition When species attempt to use the same resources. Food Water Shelter atch?v=H- wCX5R8NXM&feature= related

Different types of competition Interspecies- – 2 or more different species competing for resources. Ex lion vs. hyena

LmGudqPE Intraspecies – 2 of the same species fighting over resources Ex. lion vs. lion

Predation A Predator vs. prey relationship. Predator eats the prey. The prey is the food for the predator. cM cM

Parasitism The parasite takes nourishment from the host. The host is harmed in the relationship, often weakened and exposed to disease. g g

Mutualism Each organism benefits in the relationship. The acacia tree and ants- – Tree provides food and shelter – Ant provides protection from predators –

Commensalism One organism benefits and the other is indifferent or unharmed. Whale shark and remora fish. m/watch?v=e4xrdeagy YM m/watch?v=e4xrdeagy YM

Symbiosis A relationship in which two different organisms live in close association with each other.

Mimicry Acting or looking like another more dangerous animal.

Question #1 What does a parasite get from its host? nourishment

Question #2 Why is it beneficial for the parasite to let its host live? It then receives an unlimited supply of food and a place to live.

Question #3 What is the name of the relationship when species A benefits and species B is killed. Predation

Question #4 What is the name of the relationship when species A and B positively affect each other? Mutualism

Question #5 What is the name of the relationship when species A and species B negatively affect each other? Competition

Question #6 What is the name of the relationship when species A benefits and species B is unaffected? Commensalism

Question #7 What is the name of the relationship when species A benefits and species B is harmed but not killed? parasitism

Question #8 What is the relationship? Lion and antelope Whale shark and remora fish Tapeworm and humans A bee pollinating a flower and drink the nectar as well All the animals at a watering hole Predation Commensalism Parasitism Mutualism Competition
