Answer:
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. Explanation: The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism, trophically transmitted parasitism, vector-transmitted parasitism, parasitoidism, and micropredation.
The following is the correct order of the whole phosphorus cycle:
1. Erosion and weathering of the rock deposits the phosphorus into water.
2. Aquatic plants absorb and assimilate the dissolved phosphate.
3. A fish consumes aquatic plants.
4. The fish is caught and consumed by a bear.
5. The bear, after a fruitful life, dies from an old age.
6. Decomposition of the dead bear discharged phosphorus into the soil.
7. The soil washes into a lake, where it sinks to the bottom to turn into a sedimentary rock.
