Explanation:
In the shown food web, almost all organisms are the food source for the fungus. They feed on dead organic matter. Fungi breakdown dead organic matter into basic nutrients such as derivatives of C, N, O, P, K, etc. These nutrients then act as building blocks of macromolecules amino acids, carbohydrates, fats, nucleic acids required for the biogeochemical functioning of the food web.
PS: Fungi work as primary decomposers in an ecosystem like bacteria.
Answer:

Answer:
2.8 × 10² g
Explanation:
Given data
Step 1: Convert 25°C to the absolute scale
When working with gases, we have to convert the temperatures to the Kelvin scale, using the following expression.
K = °C + 273.15 = 25°C + 273.15 = 298 K
Step 2: Calculate the moles of chlorine gas
We will use the ideal gas equation.
