Types of relationships
- Predation, One animal kills and eats another for food. Predator is the one hunting, prey is the one being hunted. Keystones Species = a s[cecies that holds the ecosystem togheter, most of the time is the apex predator
- Symbiosis, An interaction in whitch two or more physically close organisms co exist with each other without competing, One species always benefits
- Parasitism, One organism benefits itself while the other is harmed. But the parasite (the one benefiting) does not try to kill the host as long as it dosent benefit the parasite. ( the parasite will allow the host to live until it can survive and spread )
- Commensalism, one organism is benefitted while the other is unaffected. (one is neither harmed or benefitted whilst the other benefits itself = Fish under shark that eats the sharks left overs)
- Mutualism, Both organisms involved are benefitted.
VOCAB
- Competition, A relationship that exists between two or more orgamisms competing for limited reasources
- Intersepecific Competition, Where competition is occuring in different species
- Intraspecific, Where competition is occuring in the Same Species
