The following option are correct:
1. There will be interspecific competition between foxes and tigers.
Competition for food between animals of different species is called interspecific competition while that between the same animal species is called intraspecific competition.
2. The energy received at the tropic level of carnivores will be less than the usual amount.
The energy received at the trophic level become reduced because the amount of food available for the carnivores has been reduced.
3. There will be decreased biomass at the trophic level of carnivores.
Decrease biomass will occur at the trophic level of carnivores because, those carnivores that can not survive the food reduction problem will die off.
Answer: One of the ways the path of a nitrogen atom begins is as a part of an ammonium ion. A plant takes up the ion and uses it to make an organic molecule through assimilation. The organic molecule falls back to the ground as part of a leaf. The leaf is decomposed by bacteria, and it is converted back to ammonium by ammonification. The ammonium ion is then converted to nitrite by nitrifying bacteria through nitrification.
Explanation: That's what popped up after I hit submit so that's the answer hope this hepls.
Answer:
<u>The correct statements are A and D</u>
A.The photo-system will still continue to split water because it is still losing electrons
D.The ATP yield would be unaffected
Explanation:
DCPIP is a redox-sensitive dye, not an electron transport chain blocker, and hence, imparts change in the wavelength when electrons are transferred. This allows rest of the steps of photo-system to be carried on normally, including splitting of water to generate oxygen as well as generation of ATP.
Answer:
Skin pigmentation is due to the production of melanin pigment. It is a polygenic trait i.e. it is controlled by many genes. All the alleles of these genes have additive effect which means that each dominant allele contributes a little to the trait. As the number of dominant alleles increase, more contribution occurs and more pigment is produced. Hence, there is a wide range of phenotype and it is present in a continuous spectrum rather than discrete units. Whereas in Mendelian model, a dominant trait always masks the effect of recessive trait and it does not matter if there is one or more than one dominant allele. Hence, according to Mendelian model AA and Aa will have same phenotype but according to additive allele concept they will have different phenotype.
Biracial individuals have different combinations of the skin pigmentation alleles so their skin colors can vary from each other and from their parents' too. Even if they have a mixed skin color the degree of mixing is not same in every individual. Unlike Mendelian trait it is difficult to predict their skin color because so many genes with additive effect are involved.
Hence, skin color can not be explained by Mendelian model.
Answer:
The most abundant type of pollution in national parks at that time was air pollution and it had begun to reduce biodiversity as organisms were leaving polluted areas for cleaner ones, or they simply were not able to survive.
