Write an equation here that shows the relationship between gross and net primary production.

Biology
1 answer:
Sindrei [870]3 years ago
7 0

Answer:

Net Primary Production = Gross Primary Production - Respiration

Explanation:

  1. <u>Gross Primary Production (GPP)</u> = The total amount of chemical energy that is expressed as carbon biomass created by primary producers in unit time.
  2. <u>Respiration (R)</u> = A fraction of fixed amount of energy that is used by primary producers for the cellular respiration and maintenance of existing tissues.
  3. <u>Net Primary Production (NPP)</u> = The remaining amount of the fixed energy.

Therefore, the equation that shows the relationship between gross and net primary production is,

<em>Net Primary Production (NPP) = Gross Primary Production (GPP) - Respiration (R)</em>

Net primary production is the amount of energy that remains behind after the consumption of some fraction of energy in respiration from the gross primary production.

Dead animals and plants and wastes
Margarita [4]
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.

When adult amphibian skin harbors populations of the bacterium, Janthinobacterium lividum (Jl), chytrid infection seems to be in
ira [324]

Answer:

C: Take infected amphibians and assign them to two populations. Leave one population alone; inoculate the other with Jl. Measure the rate at which infection proceeds in both populations.

Explanation:

In scientific investigations, the best way to determine the effect of certain experimental factor on the population of study is to have a baseline for comparison. This is usually referred to as controlled experiment.

<em>In the case of the observation that chytrid infection in amphibians seems to be inhibited by Janthinobacterium lividum, the best way experimental design is to get a population of amphibians suffering from the disease, divide them into two groups and subject them to the same conditions except the introduction of Janthinobacterium lividum to the skin of one of the groups.</em>

<em>A suitable method can thereafter be employed to measure the rate at which infection proceeds in both population. If indeed, the bacterium has the capacity to inhibit the infection, the rate of infection in the group with the bacterium will be significantly less than that of the group without the bacterium. </em>

The correct option is C.

Cell walls are impermeable to transport of most materials required for bacterial nutrition.
mezya [45]

The given statement is False.

The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.

The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.

The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.
