- Competition.
- Predation.
- Parasitism.
- Mutualism.
- Commensalism.
What are the 5 interactions in an ecosystem?
The interaction among organisms within or between overlapping niches can be characterized into five types of relationships:
competition, predation, commensalism, mutualism and parasitism
.
What are the 2 types of interactions?
At the coarsest level, ecological interactions can be defined as either
intra-specific
or inter-specific. Intra-specific interactions are those that occur between individuals of the same species, while interactions that occur between two or more species are called inter-specific interactions.
What are the 3 types of biotic interactions?
- Parasitism.
- Commensalism.
- Mutualism.
What are the types of interaction?
| type of interaction sign effects | mutualism +/+ both species benefit from interaction | commensalism +/0 one species benefits, one unaffected | competition -/- each species affected negatively | predation, parasitism, herbivory +/- one species benefits, one is disadvantaged |

What is positive and negative interaction?
Organisms
living together in a community influence each other directly or indirectly under natural conditions
. The interaction between organisms may not be always beneficial to all the interacting counter parts. …
What is beneficial interaction?
Positive interactions are
those in which organisms cooperate in a way that provides a net benefit to at least one participant
. Mutualism, facilitation, and commensalism are all examples of positive interspecific interactions that occur across ecosystems.
What is a competition relationship?
Competition is
a relationship between organisms that strive for the same resources in the same place
. … Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area.
What is a mutualistic relationship?
A mutualistic relationship is
when two organisms of different species “work together,” each benefiting from the relationship
. One example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. The oxpeckers get food and the beasts get pest control. …
What are the basic needs of all living cells?
Lesson Summary
But because we are all living organisms, we all have five basic needs for survival:
sunlight, water, air, habitat, and food
. In different ways, these basic needs help keep our cells running the way they should.
What is bio diversity?
Biodiversity is a term used to
describe the enormous variety of life on Earth
. … Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence.
What is a biotic interaction?
Biotic interactions occur
when organisms living in the same community directly or indirectly influence one another
.
Is Commensalism positive or negative?
| Name Description Effect | Commensalism A long-term, close association between two species in which one benefits and the other is unaffected + / 0 | Parasitism A long-term, close association between two species in which one benefits and the other is harmed + / – |

What are 3 biotic and abiotic factors?
Examples of abiotic factors are
water, air, soil, sunlight, and minerals
. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
Which is positive biotic interaction?
In positive interactions,
organisms exchange key resources such as nutrients, protection, transportation, or habitat to a net benefit for at least one participant
. … It is well known that interaction outcomes vary with abiotic and biotic context.
How do biotic and abiotic factors interact?
In general,
abiotic factors like rock, soil, and water
interact with biotic factors in the form of providing nutrients. … The water, phosphorus, nitrogen, and carbon cycles are examples of this. Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area.
