This is called 'controlled' or 'prescribed' burning. Usually fires in the environment are regarded as undesirable and dangerous, but fires actually fulfil an important ecological role, and animals and plants had adapted to a certain frequency and intensity of fires. The seeds of some trees or grasses germinate after forest or grass fires, as the more open conditions after a fire allows the seedlings to compete and avoid being shaded and smothered by more established trees. Unfortunately, farming and forestry practices have in many cases resulted in a reduction of fires. A reduction in the frequency of fires also allows the build up of dead wood, and when a wild fire does occur, the amount of available fuel results in very hot, large and damaging fires. Therefore, management of forests and other environments such as prairies often use controlled burns to avoid the buildup of dead organic mass and to replicate the natural fire cycle.
THe bacteria that lives in the nodules of legumes are the only ones able to fix nitrogen gas into ammonia, which is later fixed by other bacteria in the soil to nitrites and nitrates that the plants can use.
some bacteria also performs denitrification, which converts ammonia back to nitrogen gas, allowing the cycle to continue

Answer:
D. cytokines differs in plant cells and animal cells
Explanation:
A. is false, as prokaryotes to not divide by mitosis. They divide by binary fission.
B. is false. Animal Cells do not have cell walls. Prokaryote and Plant cells have cell walls. Animal Cells have plasma membranes.
C. is also false. Eukaryotes have line-like chromosomes. Prokaryotes have a single circular chromosome.
D. IS true. Cytokinesis differs in plant cells from animal cells. This is mainly due to the cell wall in the plant cell.
The producers that it eats will increase in population. The secondary consumers will decrease the most in population because they eat the primary consumers. The tertiary consumers will also decrease because they eat secondary and primary consumers.
