Explain how the biomass of a species is limited by their trophic level.

1 answer:

3 0

Energy, the many types of Biomass. There are three levels, primary consumers, secondary consumers, and tertiary consumers. Lower level animals have a greater species biomass its because higher level consumers are limited by there number of biomass.

Advocard [28]

As the name says the goal of the descriptive investigation is to describe.
This type of investigation has no hypothesis, but only a question. With this type of investigation Tyler will be able to observe all types of insects and study the insects in many various aspects and provides a bigger overview, because it uses both quantitative and qualitative data.

Prokaryotes and eukaryotes cells

Alborosie

Answer:

Solution

verified

Verified by Toppr

Correct option is

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Prokaryotic cells have a cell wall surrounding the cell membrane. The fluid matrix filling the cell is the cytoplasm. There is no well-defined nucleus. The genetic material is basically naked in the cytoplasm, not enveloped by a nuclear membrane. The nuclear membrane is found in eukaryotes. The prokaryotic cells lack mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, microtubules, microfilaments, and centrioles.

Cytoplasmic streaming, also called cyclosis, is the directed flow of cytosol (the liquid component of the cytoplasm) and organelles that aids in the delivery of organelles, nutrients, metabolites, genetic information, and other materials to all parts of the cell. In prokaryotes, cytoplasm does not show cyclosis or streaming movements.

So, the answer is A.

Name two abiotic factors that contribute to the growth of phytoplankton?

Lynna [10]

Answer:

(autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize

Explanation:

The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize. All of these factors are crucial to the primary producer!

Bacterial communities are an important part of biological diversity and biogeochemical cycling in aquatic ecosystems. In this study, the relationship amongst the phytoplankton species composition and abiotic environmental factors on seasonal changes in the community composition of free-living and attached bacteria in Lake Erhai were studied. Using Illumina high-throughput sequencing, we found that the impact of environmental factors on both the free-living and attached bacterial community composition was greater than that of the phytoplankton community, amongst which total phosphorus, Secchi disk, water temperature, dissolved oxygen and conductivity strongly influenced bacterial community composition. Microcystis blooms associated with subdominant Psephonema occurred during the summer and autumn, and Fragilaria, Melosira and Mougeotia were found at high densities in the other seasons. Only small numbers of algal species-specific bacteria, including Xanthomonadaceae (Proteobacteria) and Alcaligenaceae (Betaproteobacteria), were tightly coupled to Microcystis and Psephonema during Microcystis blooms. Redundancy analysis showed that although the composition of the bacterial communities was controlled by species composition mediated by changes in phytoplankton communities and abiotic environmental factors, the impact of the abiotic environment on both free-living and attached bacterial community compositions were greater than the impact of the phytoplankton community. These results suggest that the species composition of both free-living and attached bacterial communities are affected by abiotic environmental factors, even when under strong control by biotic factors, particularly dominant genera of Microcystis and Psephonema during algal blooms.

) what basic principles of antibody-mediated immunity are utilized in an elisa assay

Komok [63]

The most crucial principle of ELISA (enzyme-linked immunosorbent assay) is a highly specific antibody-antigen interaction.
ELISA is a biochemical technique used to detect the presence of an antibody or an antigen in the biological sample. Simply described, in an ELISA, an antigen is immobilized on a solid surface and then a specific antibody is applied over the surface so that it can bind to the antigen. The antibody is usually linked to an enzyme, and in the final step, a substrate for that enzyme is added. The enzyme can convert it to some detectable signal, most commonly a color change. Medical usage of ELISA is in the diagnosis of HIV infection, pregnancy tests, measurement of cytokines…
