Biodiversity is essential to an ecosystem's resistance against viruses and famine. In history, there has been many cases in which a lack of biodiversity has allowed a virus or disease to endemically wipe out an entire species of plant. This will subsequently affect all consumers of each trophic level. Ex: A disease that attacks the DNA of only one certain species of plant would cause decreases in the population of the organisms that rely on eating that plant, the organisms that rely on eating those organisms, and so on. This is caused by a decrease in food source, thus not being able to sustain the ecosystem's demand, thus naturally killing off any organisms that would not be able to find a sufficient food source.
Answer:
Overpopulation in the area's main source of prey, such as rabbits, mice, etc.
Explanation:
A hawk is a predatory creature. That means that it feeds off of prey, such as mice or rabbits. In the case that the population saw a sudden decrease, the population sizes of the hawk's main source of prey would increase due to hving less of a threat towards their own survival.
Water is photolysed to produce electrons, H+ ions and O2.
The equations is 2H2O ->4H+ + 4e- + O2
Answer:
Nucleus (as nuclear DNA),mitochondrial(mitochondrial DNA) and chloroplasts.
DNA is packed tightly around protein called Histones, in Eukaryotes cells;so that many molecules can easily be held together as chromosomes.
Chromosomes are thread-like structure in nucleus of cells.The histones provide support to the DNA molecule
The part DNA molecule coded for by a polypeptide is GENE, therefore in the nucleus of cells, DNA contains GENE,and the gene and DNA are packed in chromosomes,DNA appears as circular DNA mitochondria
Explanation:
Answer: Landscape
