Answer:
Option 4, Organisms in level D are heterotrophic.
Explanation:
Generally in a energy level or trophic level system, organisms are arranged on a pyramid scale in such a way that organism lying at the level A or the base of the pyramid are producers. They obtain energy from the sun and produce food for other organisms. Organism in level B is a herbivore which feed upon the plants to gain food and energy. In level C organisms that feed upon herbivores i.e the carnivores lies. At level D lies the microorganisms that feed upon dead remains of high order animals and plants. Hence, organisms at level D are called heterotrophs.
Thus, option 4 is correct
Tress and plant release carbon and respiratory
Answer:
question no 1 answer
A root hair,or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye and light microscope. They are found only in the region of maturation of the root. Just prior to and during root hair cell development, there is elevated phosphorylase activity. Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. Another adaptation that they have is a large permanent vacuole.

Answer: Stems hold the plant upright and support it. They also transport water, minerals and sugars to the leaves and roots.

Answer:
All of them
Explanation:
The effect may not be real because we don't know if the results are reproducible: Peers can identify flaws in the experimental design because an experiment must have a clear design in order to be reproducible by other researchers or else they would not have scientific validity.
The treatment kills cancer cells, but it might simply be a poison that kills all cells—even normal cells: It is possible that in the design of the experiment carried out only cancer cells were used but it had not been performed in healthy cells, which would imply the possibility that the fungus kills all the cells.
Cell samples were taken from too few patients: This may be another mistake because when only a small sample is analyzed it is not certain if the fungi are the ones that kill the cancer cells or are other conditions of the analyzed patient.
Two of the above are true
