Answer:
Without fires, there would be no life on Earth
. Fires are key to maintaining the proper oxygen concentration in the atmosphere; fire regulates the carbon cycle and life, as we know it, is based precisely on carbon
Explanation:
Although we tend to think of fires as a human invention that kills plants, animals, people, fire, as with rain or wind, is an essential natural component, basic to maintain the planet's biodiversity.
As for example, grassland ecosystems are also benefited by the same fires that allow renewal, and generate natural sustainability on the earth through the carbon cycle.
They are multicellular, heterotrophic, they have no respiratory organs, and their digestion is intracellular!
Answer:
In the natural world, limiting factors like the availability of food, water, shelter and space can change the population of any living organism. Other limiting factors include:competition for resources, predation and disease can also impact populations.
Explanation:
Answer:
A process of change in a population through genetic variation.
Explanation:
Evolution is the process of change in heritable characteristics of populations of organisms over several generations as it allow natural selection in it.
Genetic variation which refers to differences in gene frequencies is an important force in evolution which relies of natural selection to cause an increase or reduce gene frequencies in a population. Evolution lead to changes in genetic material of populations over time which make them to develop genes that will allow them to adapt to their environment for survival and reproduction.
