Community ecology is an expanding and rich subfield of ecology. Ecologists investigate the factors that influence biodiversity, community structure, and the distribution and abundance of species. These factors include interactions with the abiotic world and the diverse array of interactions that occur between species.
What do you mean by community ecology?
community ecology, study of the organization and functioning of communities, which are assemblages of interacting populations of the species living within a particular area or habitat.
What makes a community ecology?
In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
What is an ecological community and why are they important?
Ecological communities can be envisioned as collections of species that are organized into food chains and webs in which each species is a consumer of resources and is itself a resource for other consumers. Ecologists call these consumptive interactions trophic interactions.
What is the purpose of ecology?
Ecology is the study of the environment, and helps us understand how organisms live with each other in unique physical environments.
What is community ecology write the different characteristics of community ecology with suitable example?
In secondary succession, a new community replaces the first one after the disturbance. The pattern often starts at the pioneer species, such as grasses and perennials. After some time, higher forms of plant species (e.g. shrubs and pines) grow. They are referred to as the intermediate species.
What are the types of community ecology?
There are two main types of community.
- Major Community. A major community is the smallest ecological unit which is able to sustain itself and is self-regulating. …
- Minor Community. …
- Trophic Organization. …
- Dominance. …
- Interdependence. …
- Community Structure. …

What is ecosystem ecology example?
Ecosystem ecologists look at relationships between organisms and their environment. For example, in an aquatic ecosystem, an ecosystem ecologist might examine the relationships between the aquatic environment and the plants and animals that call it home.
What is an ecological community example?
Species Interactions, Food Webs, and Ecological Communities. An ecological community is defined as a group of actually or potentially interacting species living in the same place. … River food webs in forested headwater streams are good examples of this.
How is an ecological community different from a human community?
Ecosystems are composed of all of the various living organisms, along with the abiotic factors that impact them. … The community level consists only of living organisms and their interactions and does not factor in the abiotic interactions.
Why are ecological interactions important?
Individual organisms live together in an ecosystem and depend on one another. In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival. … One category of interactions describes the different ways organisms obtain their food and energy.
How does ecology affect the environment?
Ecological Impact is the effects left on organisms and their environment due to actions made by humans and natural occurrences. These changes can be beneficial or adverse to the ecosystem. An example of ecological impact can be seen in the case of invasive species.
As a body of ideas, social ecology envisions a moral economy that moves beyond scarcity and hierarchy, toward a world that reharmonizes human communities with the natural world, while celebrating diversity, creativity and freedom.
