a close long-term relationship between two species that usually involves an exchange of food or energy

What is commensalism?

A symbiotic relationship that benefits one species but does not hurt or help the other species

A symbiotic relationship that benefits one species and harms the other species.

What is the parasite in a parasitic relationship?

The organism doing the harming.

A symbiotic relationship in which both organisms benefit.

Give an example of a commensalism relationship and be able to explain why it is a commensalism relationship.

Ex. Cattle Egret and Cattle, Barnacle and Whale., Epiphytes and Trees.

Give an example of a parasitic relationship and be able to explain why it is parasitic.

Ex. Tick and Dog, Human and leech. Cat and roundworm, Human and Tapeworm.

Give an example of a mutualistic relationship and be able to explain why it is mutualistic.

Ex. Bees and flowers, Sea anemone and Clownfish, Hippo and Barbel fish, Moray Eel and Cleaner Shrimp

What is a cooperative relationship and provide an example.

a connection where individuals or groups work together to achieve a shared goal through mutual support. Ex. Leaf cutter ants carrying leaves together to build their nest. OR Elephants cooperate together to raise young and watch for predators.

What is a predator-prey relationship and provide an example.

a relationship where one organism eats another organism.

organism doing the eating or hunting of another animal.

the organism that is getting eaten or hunted by another organism.

What is a competitive relationship and provide an example.

A struggle between organisms for limited resources like food, water, territory or mates. This can occur between members of the same species or members or different species. Ex. Trees competing for sunlight. OR Wolves and Ravens compete for meat.

What is the difference between a symbiotic relationship and a predator and prey relationship?

Predator and prey is a short term immediate relationship that does not ALWAYS occur. A symbiotic relationship is a close relationship that almost ALWAYS occurs and is long-term.

What is a intraspecific competitive relationship?

A relationship where same species are competing for food, water or shelter. Ex. Trees fighting for sunlight.

What is an interspecific competitive relationship?

A relationship where different species are competing for food, water or shelter. Ex. Wolves and ravens fighting for meat.
