Summary Introduction
Introduction:
In the ecosystem, the processing of the matter as well as the energy takes place. The flow of energy in the ecosystem is not similar to the matter. The energy from the sun in the form of radiant energy reaches Earth and is converted to heat and radiated back into the space.

a. 80%
b. 100%
c. 60%

Forest trees have trunks, branches, and big roots, contributing to large amounts of total biomass. Grasslands have comparatively less biomass, but have a larger net primary production than that of forests. Why is this so?
A. Less respiration is needed in the forest habitat
B. More biomass is added in a grassland in the same time as that of forests
C. The number of consumers within the forest is greater
D. Solar energy is converted to chemical energy at a much higher rate in forests
The total amount of living tissue within a given trophic level is called the:
O A. Biomass
O B. Energy mass
C. Organic mass
O D. Trophic mass
