Vegetation	$\%$ of energy absorption
a) Aquatic ecosystem	$15-16\%$
b) Grassland	$14-15\%$
c) Mixed forest	$13-14\%$
d) Modern $C_3$ crops	$12-13\%$
e) Modern $C_4$ crops	$10-12\%$

Find the correct match.

Answer 1

The correct option is C A

An ecosystem is normally an open system because there are a continuous and variable entry and loss of energy and material. The ecosystem is the basic fundamental unit of ecology which includes both the organism and the non-living environment is influencing the property of each other and is necessary for the maintenance of life. The whole Earth can be known as biosphere or ecosphere.

Various plant and various vegetation have a different level of energy absorption. There is a grassland ecosystem and a forest ecosystem and many other.

So, the correct option is 'C'
