MindMap Gallery The level of life under the macro structure (individual, population, community)
The structural levels of living systems include cells, tissues, organs, systems, individuals, populations, communities and ecosystems. These levels interact and influence each other, and together constitute the whole life system.

The level of life under the macro structure
individual
A single organism in which an individual and several organs and systems cooperate to complete complex life activities. A unicellular organism is an individual composed of one cell
microorganism
animal
plant
Virus
RNA virus
HIV virus, tobacco mosaic virus, Ebola virus, SARS virus, measles virus, new coronavirus
DNA virus
Plague, tumor viruses, bacteriophages, hepatitis B virus, chickenpox virus
population
A collection of the same biological individuals in a certain space during the same period. The basic unit existing in population organisms is the basic unit of biological evolution and the basic component unit of biological communities.
population density
The number of individuals in a population per unit area or unit volume is the population density
Population density is the most basic quantitative characteristic of a population
Direct factors affecting population number and population density
Birth rate, death rate, immigration rate, emigration rate
Indirect influencing factors of population number and population density
Gender ratio and age structure
investigation method
sampling method, mark-recapture method, sampler sampling method, one-by-one counting method
method
Not suitable for clumping or trailing monocots
Either remember the upper left border or the lower right border
Guaranteed random sampling
mark refill method
Adaptable to populations with strong mobility and large range of activities
Sampler sampling method
Suitable for small animals in the soil
one by one counting method
Suitable for populations with small distribution range and large individuals
Factors affecting population density
abiotic factors
Sunlight, temperature, water humidity
density constraints
Climate factors such as climate and drought and natural disasters such as earthquakes and fires
non-density constraints
Natural enemies are related to biological factors such as food
biological factors
competition for prey
community
A biological community is composed of certain animals, plants and microorganisms. Species are interconnected
community structure
Species composition is an important characteristic that distinguishes different communities and is also the most important factor in determining the nature of a community.
The number of species in a community is called species richness
Dominant species
Not only are the number of species large, they also have a great impact on other species in the community, and they often dominate
interspecific relationships
Original collaboration
Living together benefits both parties, and you can live alone after separation.
Mutualism
The two creatures live together, depend on each other, and benefit each other. With the total death
parasitic
One organism obtains nutrients from the fluids, tissues, or digested substances of another organism. Usually harmful to the host
prey
One organism feeds on another organism
There are more prey than predators. Generally speaking
The number of individuals increases first, that of the prey, and then that of the predator.
interspecific competition
Two or more organisms are mutually exclusive by using the same limited resources and space.
Either one will wax and wane or you will live and die.
Spatial structure
horizontal structure
Changes in horizontal terrain, differences in soil moisture and salinity, and differences in light intensity
Differences in the growth characteristics of organisms themselves. and the impact on humans and animals
Mosaic distribution
vertical structure
The significance is to significantly improve the utilization rate of environmental resources
The layering phenomenon of plants determines the layering phenomenon of animals
ecological niche
It is the result of co-evolution between species in the community and between organisms and the environment.
Second, the role of species in the community. location in space. Possession of resources. Relationship with other species
Main types of communities
Farmland biome, wetland biome, desert biome, grassland biome, forest biome
community succession
primary succession
No living things have ever existed, such as on sand dunes, volcanic rocks, and glacial mud. succession
slow
secondary succession
The original soil conditions are basically preserved, and even the seeds and other propagules of the plants are retained. where the bunker took place
high speed
Influencing factors
changes in the external environment. In-depth migration in and out
changes between populations
Cells, tissues, organs, systems, populations, ecosystems, biosphere
