Community, population, species, and the relationship between species

If species can be treated as individuals, then.

Species (individuals) Populations Community.

Many individuals (species) are populations, and the populations of different species add up to communities!

Populations that are connected form communities, and species that are co-located make up populations.

Species-population-community.

In a pond, grass carp is a species, turtles are a species, and aquatic weeds are also a species. And by many of the same animals or plants (such as a school of grass carp or one.

A group of turtles or a bunch of aquatic weeds) is a population. All the different species of fish in a pond are combined to form a colony.

All grass carp in the pond, this is a population.

All the fish in the pond plant microorganisms, which are the community.

Grass carp is a species.

That's about it.

Species are the basic units of taxonomy. A species is a natural group formed by the same organisms that reproduce with each other, are reproductively isolated from each other and occupy a certain ecological niche in nature. In ecology, all individuals of the same species that occupy a certain space for a certain period of time are called populations, and biological communities refer to the regular combination of multiple biological populations with direct or indirect relationships, with complex interspecific relationships.

That is, in a certain time and space, all the same species constitute a population; And the populations of different species make up a biome.

Difference Between Population and Community:

First, the concept is different.

1. Population refers to the sum of individuals of the same species in a certain space and time.

2. Community refers to the sum of various biological populations that have direct or indirect relationships with each other in a certain natural area, also known as biological community.

Second, the characteristics are different.

1. The population has statistical characteristics such as population density, birth and death rates, age composition, and sex ratio.

2. The characteristics of a community are not included by the individual populations that compose it, but can only be manifested at the overall level of the community. The characteristics of the community mainly include richness, dominant species, interspecific relationships, community structure, ecological niche, range and boundary.

Population density refers to the number of individuals per unit area or volume, and "population density" is different from "density", the former is the "number" of individuals, and the latter is the proportion, and population density is the most basic quantitative characteristic of a population.

Forecasting agricultural and forestry pests and determining fishing intensity in fisheries require population density surveys. The population density of a population in its natural state tends to fluctuate greatly, but not indefinitely.

Birth rates, mortality rates, and migration and emigration rates all have an impact on population density. There is an upper and lower limit to the size of the population. The upper limit of population density is determined by the energy flow of the ecosystem where the population is located, and the lower limit is difficult to determine, and the homeostatic regulation of the ecosystem can keep the population density of dominant organisms within a limited range.

The population is composed of biological individuals, and then the species is formed, and the various species form a community of dao. Populations and communities are the rights of the package.

Population"It refers to the sum of organisms of a certain species in a certain area.

While"Community"It is formed by the regular combination of different populations influencing and restricting each other in a certain area.

In the basic structural law of the biological world, there are many communities of populations.

A population refers to a single species that lives together, whereas a community refers to any species in nature that is together and also has a food chain. Like a species that goes from fungi to no longer being able to eat is a community. A population is a part of a community.
