1. Predation: One organism feeds on another. 2. Competition:
Two or more organisms compete with each other for resources and space, etc. 3. Parasitism: one organism (parasite) resides in the body or body surface of another organism.
Ingest nutrients from the host to sustain life. 4. Mutually beneficial symbiosis: two organisms live together, interdependent, and mutually beneficial.
If they are separated from each other, neither or one of them can survive independently.
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.

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 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.

The differences between "interspecific relationships" and "intraspecific relationships" in organisms are:
1. The scope of existence is different: interspecific relationship refers to the relationship formed by the interaction between populations of different species, 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 an interspecific relationship in which a sharp object feeds on another organism, and it is an antagonistic and pure inter-species relationship. Intraspecific relationships do not include predation, and there is no mutual predation between a population.
1. Face-to-face bird-in-arms sleeping position.
When the two sides face each other, the man holds the woman tightly into his arms, one arm wraps around the bottom of the other's neck, and the other arm is naturally placed on the other's back, forming the greatest physical closeness. This sleeping position shows the intimacy of the two people, usually newlyweds, or intimate couples or couples. The sleeping position of the woman snuggled up to the man, in the arms of the man, will feel the greatest sense of security. >>>More
