Decompose and release to the nutrients to the sources.
The micro-organisms decompose the dead and decaying organic matters. The nutrients are absorbed from soil or atmosphere by the plants. During the absorption these nutrients are depleted from the sources.
From the plants, these nutrients are transferred to the animals at different tropic levels. After the death of plants and animals are decomposed by micro-organisms and release the nutrients to the sources which finally maintain the biogeochemical cycle of nitrogen, Sulphur etc.
Answer:
Option A 400 individuals
Explanation:
Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.
N = (MxC) / R
Where N = estimated Number of individuals in the population
M = number of individuals captured and Marked = 200
C = total number Captured the second time (with and without a mark) = 200 and
R= number of individuals Recaptured (those with a mark) = 100
Thus, we have
N = (MxC) / R
= (200 x 200) / 100
= (40,000) / 100
= 400 individuals.

Answer:
The xylem is located in the root, stem and the leaves of a plant.
The xylem contains dead cells arranged end-to-end forming continuous vessels. They have a hollow central space (lumen) through which water passes. They walls contain lignin.
The xylem carries water and minerals, up from the roots to the rest of the plant.
