The chameleon protects itself by changing its color.
Mammals and whales breathe in water
Giraffes need long necks to eat trees.
5. Imitation of stick insects and dead-leaf butterflies
6. The protective color of locusts
Examples of the relationship between biology and human life: 1. Use some bacterial viruses to make vaccines.
2. Using Acetobacter to make vinegar
3. Using Corynebacterium to produce monosodium glutamate
Humans feed on animals, plants and fungi.
5. Bionic. Such as: the invention of airplane, the invention of radar, and so on. The types of relationships between species are:
Reciprocity: refers to an interspecific relationship that is beneficial to both sides, but this relationship has not yet developed to the point of interdependence. If this relationship is dissolved, both sides can live normally. Such as anemones and hermit crabs; Aphids and ants
* * * Life: It is a mutually beneficial relationship between species. If one side loses, the other side can't live. Such as lichens (living organisms of unicellular algae and fungi); Yucca and flange moth; Termites and flagellates.
* * * Habitat: refers to the interspecific relationship that is beneficial to one party but harmless to the other, also called partial benefit. Such as double sawfish and anemone, Xie Lao and Li Xia.
Phytophagy: refers to animals eating plants, which is the most common phenomenon in biological relations.
Predation: refers to animals eating animals, which is also one of the most basic phenomena in biological relations.
Parasitism: two kinds of creatures, one benefits and the other suffers. Those who live in another species and make a profit are called parasites, and those who live in another species and suffer are called hosts. Such as Schistosoma japonicum and ascaris lumbricoides parasitic in human body.
Parasitism: Similar to parasitism, but the parasite causes the death of the host. All insect parasitism to insects is pseudoparasite, such as parasitic flies and parasitic bees.
Competition: Competition occurs when two species use the same definite shortage of resources. The result of competition is that one species will defeat another species, and even one species will be completely excluded. For example, the competition between paramecium macrophyllum and paramecium bicephalum; Competition between European larks and local larks after their introduction to North America.
Antimicrobial agent: refers to a species that inhibits the growth and survival of another species by secreting chemicals. Penicillium is a famous example.
Mutual resistance: refers to the interaction between two species, which causes both sides to suffer or die. When two pathogens invade a host at the same time and cause the death of the host, the two pathogens are antagonistic.
Neutrality means that two or more species often appear together, but there is neither benefit nor harm to each other. If a water source always attracts many animals to drink, then there is a neutral relationship between these animals.
Biology and environment are a unified and inseparable whole. Environment can affect living things, living things adapt to the environment, and at the same time, it constantly affects the environment, just like "water can carry a boat, but it can also overturn it." For example, cactus living in the desert, due to the lack of water in this environment, cactus leaves become thorns, which also shows that cactus can adapt to the environment. Living things can affect the environment, such as transpiration of terrestrial plants, which is an adaptation to land life; But at the same time, terrestrial plants can lose a lot of water into the atmosphere during transpiration, increase air humidity and adjust climate.
The best example of biological impact on the environment is the Loess Plateau, which used to be a vast forest and endless grassland. However, due to some reasons, vegetation has been destroyed, resulting in serious soil erosion and imbalance of ecological balance, leading to excessive sediment in the Yellow River and Loess Plateau ... There should be many such examples. ...
So we should protect living things, especially vegetation. ...
