Abiotic factors composed of water, light, temperature and air etc. due to fire's this primary succession was completely destroyed. Their remaining organic bodies were decomposed in soil texture.
In order to establish secondary succession there is need of water and light, because water help in translocation of food and nutrients in plants while light is important for photosynthesis.
Photosynthesis need three major components. these are H₂O, CO₂ and light, all these components are abiotic part of ecosystem. However, when secondary succession occurs, then light play a key role in changing the composition of plant community. The best example is the difference in height of plants of different community.
A The observed differences in plants height are due to genetics.
Answer:
Answered below
Explanation:
Pepetidoglycans are the structural polymers which make up the cell walls of most bacteria.
It consists of the macromolecule, glycan chains, which are repeating N-acetylmuramic acid and N-acetylglucosamine residues. These glycan chains combine or cross-link with peptide side chains (proteins) to form a mesh-like layer outside the plasma membrane of most bacteria.
Peptidoglycan is the major structural component and the basic unit of the bacterial cell wall and provides protection to the cytoplasmic membrane, mechanical rigidity and also regulates the passage of fluid, amino acids, sugar and ions, in and out of the cell.
Answer:
C. fungus-like protist
Explanation:
The fungus-like protists are organisms that seem like plants, but are much more closely related to the animals. They tend to be parasitic, thus they use a host in order to be able to get the needed nutrition. Unlike the producers, the fungus-like protists are not capable of performing the process of photosynthesis, thus they do not produce their own food. Considering these characteristics, it is no wonder that they can mostly be found on dead plants from which they can feed upon.
The answer that is not caused by a gravitational pull is two atoms come together to form a molecule because atoms form molecules because of the electrons, and not gravitational pull.
Therefore the correct answer would be,
Two atoms come together to form a molecule.
I hope that this has satisfied you.
