In ecology, a community is the biotic component of an ecosystem. It consists of populations of different species that live in the same area and interact with one another. Like abiotic factors, such as climate or water depth, species interactions in communities are important biotic factors in natural selection.
Consequently, what are the different types of interactions in a community?
6 Types of Community Interactions
- Competition. Occurs when organisms of the same or different species attempt to use an ecological resource at the same place and time.
- Predation. An interaction in which one organism captures and feeds on another organism.
What is a community level interaction?
Community-Level Interactions. when the interaction between two species leads to changes in the presence or absence of other species or to a large change in abundance of other species, then a community effect is said to have occurred. Decomposers. organisms that feed on dead organic matter. Ecological Community.
What are community interactions in biology?
Community Ecology: The Study of Symbiosis. Evolution by natural selection is driven by ecological interactions between organisms and between organisms and their environment. Today we'll explore the former. Biological coevolution is the evolutionary change of one species triggered by interaction with another species.
