Final answer:
The 5 different types of relationships among living things in ecosystems are commensalism, competition, mutualism, parasitism, and predation.
Step-by-step explanation:
The 5 different types of relationships among living things in ecosystems are:
- Commensalism: This type of relationship occurs when one species benefits from another species, but the other species is neither harmed nor helped. An example is when orchids grow on a tree and obtain nutrients and support, while the tree is unaffected.
- Competition: This relationship exists when different species attempt to use the same limited resource, leading to a struggle for survival. An example is different bird species competing for food from the same bird feeder.
- Mutualism: In mutualism, two different species have a close relationship and provide a benefit to each other. An example is the relationship between flowers and pollinators, where flowers provide nectar as food and pollinators help with the flower's reproduction.
- Parasitism: This relationship occurs when an organism lives in or on another organism and feeds off it as a source of nutrients, often harming the host organism. An example is a tick feeding on the blood of a dog.
- Predation: Predation is the relationship that exists when one organism eats another organism. An example is a lion hunting and consuming a zebra.
