Competition Organisms of two species use the same limited resource and have a negative impact on each other. - / -
Predation A member of one species, predator, eats all or part of the body of a member of another species, prey. + / -Key points:
An ecological community consists of all the populations of all the different species that live together in a particular area.
Interactions between different species in a community are called interspecific interactions—inter- means "between."
Different types of interspecific interactions have different effects on the two participants, which may be positive (+), negative (-), or neutral (0).
The main types of interspecific interactions include competition (-/-), predation (+/-), mutualism, (+/+), commensalism (+/0), and parasitism (+/-).
Introduction
When we took a tour through population ecology, we mostly looked at populations of individual species in isolation. In reality, though, populations of one species are rarely—if ever!—isolated from populations of other species.
In most cases, many species share a habitat, and the interactions between them play a major role in regulating population growth and abundance.
Together, the populations of all the different species that live together in an area make up what's called an ecological community. For instance, if we wanted to describe the ecological community of a coral reef, we would include the populations of every single type of organism we could find, from coral species to fish species to the single-celled, photosynthetic algae living in the corals. For a healthy reef, that comes out to a whole lot of different species!

Community ecologists seek to understand what drives the patterns of species coexistence, diversity, and distribution that we see in nature. A core part of how they address these questions is by examining how different species in a community interact with each other. Interactions between two or more species are called interspecific interactions—inter- means "between."
In the rest of this article, we'll take take a look at the main types of interspecies interactions seen in ecological communities. Here is a quick preview:

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 + / -
Overview: interspecies interactions
Interspecies interactions can be broken into three main categories: competition, predation, and symbiosis. Let's take a closer look at each.
Competition
In interspecific competition, members of two different species use the same limited resource and therefore compete for it. Competition negatively affects both participants (-/- interaction), as either species would have higher survival and reproduction if the other was absent.
Species compete when they have overlapping niches, that is, overlapping ecological roles and requirements for survival and reproduction. Competition can be minimized if two species with overlapping niches evolve by natural selection to utilize less similar resources, resulting in resource partitioning.
Predation
In predation, a member of one species—the predator—eats part or all of the living, or recently living, body of another organism—the prey. This interaction is beneficial for the predator, but harmful for the prey (+/- interaction). Predation may involve two animal species, but it can also involve an animal or insect consuming part of a plant, a special case of predation known as herbivory.
