Ecological Relationships Definition

The definition of ecological relationships is the interactions between organisms within a specific ecosystem or area.

Interactions between organisms within a specific ecosystem

Community ecologists examine how different species in a community interact with each other. Interactions between two or more species are called interspecific interactions.

There are five major ecological relationships:

  1. Competition
  2. Predation/herbivory
  3. Mutualism
  4. Commensalism
  5. Parasitism

Animals meeting with man

The relationship of animals meeting with a man could be of various types depending on the intentions and orientation of both the species. For example,

A caveman and a leopard may be in a competitive, predatory, or mutual relationship as follows:

  1. Competitive: Both are trying to kill the same deer.
  2. Predatory: Either one of them is trying to kill the other.
  3. Mutual: They have formed an alliance.

Competition is an ecological relationship

Ecology relationships are the interactions between the variety of organisms that inhabit the earth.

The major ecological relationships are explained below:

  1. Competition: Organisms of two species use the same limited resource and have a negative impact on each other.
  2. Predation: A member of one species, a predator, eats all or part of the body of a member of another species, prey.
  3. Herbivory: A special case of predation in which the prey species is a plant
  4. Symbiosis: Interspecific interaction in which two species live together in a long-term, intimate association.
  5. Mutualism: A symbiotic relationship between two species in which both partners benefit.
  6. Commensalism: A symbiotic relationship between two species in which one benefits and the other is unaffected.
  7. Parasitism: A symbiotic relationship between two species in which one benefits and the other is harmed.

Ecological relationship

Ecological relationships are described in 7 ways:

  1. Competition: Woodpeckers and squirrels often compete for nesting rights in the same holes and spaces in trees, while the lions and cheetahs of the African savanna compete for the same antelope and gazelle prey.
  2. Predation: wolves hunting moose, owls hunting mice, or shrews hunting worms and insects.
  3. Herbivory: cows eating grass.
  4. Symbiosis: Lactobacillus and humans, cells and mitochondria, ants and fungi, goby fish and snapping shrimp, coral and algae, and cleaner fish
  5. Mutualism: Ants feed on the honeydew produced by aphids and may offer them protection in return
  6. Commensalism: Tree frogs use plants as protection.
  7. Parasitism: Fleas or ticks that live on dogs and cats

Ecological relationships definition

All organisms are connected to each other in an ecosystem. Organisms form relationships with each other because they are connected.

Ecological relationships

Some organisms compete against other organisms for resources or space. Other organisms depend on each other to survive. These relationships are called ecological relationships.

Environmental relationships

Environmental relationships are various types of interactions between different organisms living in an environment.

Here are some amazing environmental facts that you need to know about.

  1. Human consumption of Earth’s natural resources more than tripled between 1970 and 2015. Our use of natural resources is expected to continue growing and more than double from 2015 to 2050.
  2. According to NASA, the world’s rainforests will be gone by 2100 if the current rate of destruction continues.
  3. If current patterns continue, we will have emptied the world’s oceans for seafood by 2050.

A species living on another

A species living on another can be any of these types: commensalism, parasitism, or mutualism.

A community and its physical environment together form an ecosystem, in which different organisms or populations of living things interact with each other, these relations are called ecological relations.

The plants, air, and water around us

The plants, air, and water around us all form an ecosystem.

An ecosystem is the region in which populations interact with each other.

Plants, air, and water around us form an ecosystem

Ecosystems have communities, and these communities are comprised of populations of different species.

A community differs from a population in that communities evolve to have greater biomass and species richness in a process called succession, whereas in a population, any individual evolves as a result of genetic drift.

The relationship between an organism and individuals of other species in a community involves

The relationship between an organism and individuals of other species in a community involves competition, predation/herbivory, mutualism, commensalism, and parasitism.

All of the ecological interactions are necessary for the survival of the organisms. Interdependence in nature is illustrated by the transfer of energy.

Which of the following could be true of two different species that have a competitive relationship?

Two different species that have a competitive relationship can cause death. This intraspecific competition helps nature keep the population under control.

Competitive relationship in an ecosystem

A population is a group of organisms of the same species that live in an area.

The organisms most likely to belong to the same species are more likely to have a competitive relationship.


What is the definition of an ecological relationship?

The definition of an ecological relationship is the interactions between organisms in an ecosystem. Because they are linked, organisms create relationships with one another.
Some species struggle for resources or space with other organisms. Other organisms rely on one another for survival. These are referred to as ecological relationships.

Which of the following relationships has a negative impact on both species?

The relationship that has a negative impact on both species is competition.
In interspecific competition, members of two different species use the same limited resource and therefore compete for it.

Competition negatively affects both participants, 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.
