All of the different kinds of interacting organisms living within a certain area make up an ecological community. These communities are bound together by a shared environment and the network of influence each species has on the other.
The community structure, biodiversity, and the distribution and abundance of species are influenced by a number of factors.
These factors include interactions with the abiotic world and inter-species interactions (ecological relationships).
Inter-species interaction includes competition, predation, herbivory, parasitism, mutualism, etc.

A vast geographic area sharing a similar ecosystem
A vast geographic area sharing a similar ecosystem is called a “biome.” Aquatic, grassland, forest, desert, and tundra are the five major biomes.
Furthermore, some of them can be subdivided into more specific categories like freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.
All of the biomes, i.e., all ecosystems taken together, make up a biosphere.
An area where there are many different types of organisms living together has a large amount
An area where there are many different types of organisms living together has a large amount of biotic and abiotic factors that influence them.
The biotic parts consist of all living animals, organisms and decomposers.
The abiotic factors involve water, soil, air, sunlight, temperature, and minerals.
Members of one kind of organism in an ecosystem
Members of one kind of organism in an ecosystem are called “a population.”
A population is a subset of individuals of one species that occupy a particular geographic area. In sexually reproducing species, they interbreed.
The different populations of all the species in a given area make up a
The different populations of all the species in a given area make up a biological community in which organisms interact with the environment cycle within an ecosystem.
The characteristics of a biological community are dominance, species diversity, trophic organization, stratification, dynamism, and stability.
The different species within an ecosystem that interact in various ways make up a
The number of different species in a community or ecosystem that interact in various ways make up a community, and their interaction is called symbiosis (a give and take relationship).
Symbiotic relationships are those relationships that provide at least one of the participating species with a nutritional advantage. Examples of symbiotic relationships are between fungus and photosynthetic algae and microbes and cattle.
The organisms that represent all of the different interacting species within an ecosystem make up
The organisms that represent all of the different interacting species within an ecosystem make up a biological community.
There are two main types of communities.
A major community is the smallest ecological unit that is able to sustain itself and is self-regulating. These communities are usually relatively independent of other communities.
Minor communities make up major communities. Minor communities are smaller ecological units that are not individually self-sustaining and rely on interactions with other communities.
The region in which populations interact with each other
The region in which populations interact with each other is called an ecosystem.
An ecosystem is composed of biotic and abiotic components that interact with each other to sustain life and maintain equilibrium in the environment. The presence of highly diverse populations of organisms creates a more stable and sustainable ecosystem.
What term is defined as all the populations of various species interacting in a given area?
The term “ecosystem” is defined as all the populations of various species interacting in a given area.
Fun fact: In the whole world, a total of 431 world ecosystems were identified, and of these, a total of 278 were natural or semi-natural vegetation/environment combinations.
Which of the following can be said about light in aquatic environments?
Light is an extremely important abiotic factor that heavily influences aquatic environments.
Light is a major driver of energy and material flow through aquatic ecosystems. It can also be a limiting or co-limiting resource, as well as a basis for competition.
Light intensity and spectral distribution hold the key to understanding the dynamics and variability of physical, biological, and chemical processes on all scales in aquatic ecosystems.
Which of the following terms refers to all species that live and interact in a specific area?
An ecosystem is the term that refers to all species that live and interact in a specific area.
The World Ocean is the largest existing ecosystem on our planet. It’s a source of livelihood for over 3 billion people. It covers over 71% of the Earth’s surface.
Which of the following types of systems functions without interacting with its environment?
Closed systems function without interaction with its environment.
A closed ecological system is an ecosystem that provides for the maintenance of life through complete reutilization of available material, in particular by means of cycles wherein exhaled carbon dioxide, fuel, and other waste matter are converted, chemically or by photosynthesis, into oxygen, water, and food.
Within an ecosystem, a tree is a
Within an ecosystem, a tree is a producer in the food chain.
A food chain represents a single pathway through which energy and matter flow.
Trees contribute to their environment by providing oxygen, improving air quality, reducing climate change, conserving water, preserving soil, and supporting wildlife.
Which term describes the number of different species in a community?
The term that describes the number of different species in a community is global biodiversity.
