What are the interspecific relationships? What do they mean?

Interspecific relationships refer to the relationships formed by the interactions between populations of different species, and the interrelationships between two populations can be indirect or direct, which can be harmful or beneficial.

The types of interactions described above can be simply divided into three broad categories: neutral interactions, i.e., there are no interactions between populations. In fact, there is a universal connection between living things, and no interaction is relative.

Positive interaction, positive interaction can be divided into three categories according to its degree of effect: partial symbiosis, primitive cooperation and mutual-beneficial symbiosis. Negative interactions, including competition, predation, parasitism, and partiality.

Positive interaction.

1 Symbiosis of partial benefit.

Only one party is advantageous and is called partial symbiosis. Such as orchids grow on trees.

on the branches, making it easier for themselves to get sunlight and the roots absorb nutrients from the humid air. Barnacle.

Epiphytic in whales.

or crab on the back. The suction cup on the top of its head is attached to the belly of the shark, etc., and it is believed that one party is beneficial and the other is harmless.

2. Mutual benefit and symbiosis.

It is beneficial to both parties and is called mutual benefit symbiosis. Most of the world's biomass.

It is dependent on mutual benefit and symbiosis. The roots of dominant plants in grasslands and forests mostly symbiotize with fungi to form mycorrhizae, most flowering plants rely on insect pollination, and the digestive tract of most animals also contains microbial communities. The mutualistic symbiosis of two organisms, some of which are facultative, that is, one derives benefits from the other, but does not reach the point where it cannot survive without the other; Others are obligate, and the mutually beneficial symbiosis of obligate can also be divided into unilateral and bilaterally obligate.

3 Original collaboration.

Primitive collaboration can be thought of as another type of symbiosis, whose main feature is that two groups interact with each other, both parties benefit, but the collaboration is loose. After separation, the two sides were able to survive independently.

Such as coelenterates on the back of a crab.

It can play a camouflage protection role for crabs, and coelenterates use crabs as a means of transportation, so that they can obtain food on a larger scale. For example, some birds peck at ectoparasites on ungulates and act as carnivores.

When it comes, it can be alarmed, which is very beneficial to the common defense of natural enemies.

Interspecific relationships. It refers to two cohabitations, where one party benefits and the other party is harmless or harmless. The former is called the cohabitant, and the latter is called the host.

Cohabitants are active. According to the symbiosis status, it is divided into external symbiosis and internal symbiosis. After separation, some cohabitants are often unable to live independently.

This is a relatively close interspecific partnership.

Do a teardown tutorial to teach you how to clean it thoroughly. The battery design can only be used continuously for more than 10 minutes when fully charged, and it would be good if it could be plugged in with an external power supply for continuous use.

The differences between "interspecific relationships" and "intraspecific relationships" in organisms are:

1. The scope of existence is different: the interspecific relationship is.

Refers to the relationship formed by the interaction between different populations of property rights, which exists between several different populations. The interrelationship between individuals that exists within an biological population is called intraspecific relationship, so intraspecific relationship is the relationship that exists within a population;

2. Different behaviors included: interspecific relationships include: symbiosis, predation, parasitism, mutual-beneficial symbiosis and other relationships. Intraspecific relationships include: density effect, animal and plant behavior, domain behavior, social hierarchy, communication behavior, and altruistic behavior.

3. Differences in predatory behavior: interspecific relationships include predatory behaviors, and predatory relationships refer to the interspecific relationships in which one organism feeds on another organism, which is an adversarial mutual relationship between species. Intraspecific relationships do not include predation, and there is no mutual predation between a population.

The interspecific relationship is the relationship between different species, for example, sheep are animals, grass is plants, and their relationship is that sheep eat grass.

Intraspecific relationships are relationships between the same species, just as humans have parents and relatives.

The interspecific relationship isRelationships between different species, there is parasitism, predation, cooperation, competition.

Intraspecific relationships areRelationships between the same speciesThere is intraspecific competition and intraspecific mutual assistance.

There is competition and mutual assistance in interspecific relationships.

Intraspecific relations have struggles, parasitism, predation.

Intraspecific relationships are relationships between different individuals of the same species.

Including intraspecific mutual aid and intraspecific struggle.

Interspecific relationships are the relationships between different species of organisms.

Including: parasitism, mutuality, symbiosis, symbiosis, competition, predation.

The diagram of the four major interspecific relationships is explained as follows:

1. Parasitism. In the parasitic relationship, the general parasite is a small individual, the host is a large individual, and the small eats the large. Moreover, most of them benefit one party and one suffers, and even causes the host to fall ill or die.

At the same time, the two parasites are mutually conditional, mutually restrictive, and co-evolve. Parasitism is an adversarial interrelationship between species of organisms.

2. Symbiosis. The two co-living conditions create favorable living conditions for each other, which is more advantageous than when they live alone, and they have more vitality in the hall; Interdependent, interdependent, and once separated, neither party can live normally.

3. Competition. Together, two co-exist and struggle for limited nutrition, space, and other common needs. The result of competition may have a restraining effect on both competitors, most of the time in favor of one party, the other party is eliminated, and one party replaces the other.

4. Predation. Under normal circumstances, the predator is a large anti-sock hidden individual, and the ** eater is a small individual, and the large eater is small. The result of predation, on the one hand, can directly affect the population of the first eater, and on the other hand, it also affects the population change of the predator itself, and the relationship between the two is very complex.

Predation is also an antagonistic and inter-species relationship.
