Which statement correctly describes an interaction that contributes to the stability of this ecosystem?
A. Species E is not affected by the activity of species A.
B. Species B returns compounds to the environment that may later be used by species C.
C. Species C recycles nutrients from species B and D to obtain energy.
D. Species D is directly dependent on the autotrophic activity of species B.

Answer:

C

Explanation:

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

Food chain is the sequence of matter and energy transfers as food from one organism to another.

Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

Thus, it can be concluded that this is the main reason behind the number of snakes consumed as compared to other organisms.

Answer:

0.0300 moles LiCl

Explanation:

You can find the amount of moles using the molarity formula. The general structure looks like this:

Molar Concentration (M) = moles / volume (L)

You were given the molar concentration and volume in milliliters. Once you convert the volume to liters (by dividing by 1,000), substitute the values into the molarity formula. Then, you can simplify to find moles. The final answer should have 3 sig figs according to the given values.

50 mL / 1,000 = 0.0500 L

0.600 M = moles / 0.0500 L

(0.600 M) x (0.0500 L) = moles

0.0300 = moles

Explanation:

Dendritic cells (DC) are the professional antigen-presenting cells of the immune system. In their quiescent and mature form, the presentation of self-antigens by DC leads to tolerance; whereas, antigen presentation by mature DC, after stimulation by pathogen-associated molecular patterns, leads to the onset of antigen-specific immunity. DC has been found in many of the major organs in mammals (e.g. skin, heart, lungs, intestines, and spleen), while the brain has long been considered devoid of DC in the absence of neuroinflammation. Consequently, microglia, the resident immune cell of the brain, has been charged with many functional attributes commonly ascribed to DC.

The techniques to estimate population size are:

Population size estimation refers to the process of determining the number of individuals in a particular population. It is an important aspect of ecological and conservation research because it provides critical information about the status of a species and the health of an ecosystem.

There are several methods that can be used to estimate population size, including direct methods such as counting individuals, and indirect methods such as mark-and-recapture or sampling.

These methods can vary in their accuracy, practicality, and cost, and the choice of method often depends on the species being studied, the available resources, and the research objectives. Population size estimation is a key component of wildlife management, conservation planning, and biodiversity assessment.

Pollution can come from both natural sources and human activities depending on the type of pollutant.

It is the release of substances into the environment to the extent that the well-being of plants, animals, and humans starts getting affected.

Substances that are released into the environment to the extent that they start affecting the organisms in the environment negatively are known as pollutants.

Pollutants can come from natural sources or as a result of human activities.

For example pollutants such as oxides of sulfur, methane, carbon dioxide, etc. can come from natural processes such as volcanic eruptions, activities of microbes, etc.

Pollutants such as oxides of carbon and sulfur can also be generated as a result of human activities such as the burning of coal, technological inventions, etc.

Answer:

KH2PO4

Explanation:

Organic compounds generally contain carbon and hydrogen.

Inorganic compounds are formed using other elements in the periodic table.

The right response, KH2PO4, is Option B. Since KH2PO4 is an inorganic substance, it doesn't include carbon. Potassium, hydrogen, phosphorus, and oxygen atoms make up the ionic composition. It is a potassium and dihydrogen phosphate anion salt that is used as a food ingredient and fertiliser.

Contrarily, organic substances are those that have carbon and hydrogen atoms in them. The organic molecules C6H1206, CH3COOH, C2H6O, and C2H5OH are a few examples.

These substances differ from inorganic substances in that they include carbon atoms. As KH2PO4 is an inorganic chemical, Option B is the best choice for the right response. Contrarily, organic chemicals are not inorganic since they include carbon atoms.
