Fungi produce the enzymes necessary to decompose chemically complex substances that are found in wood.
Q. What determines the productivity of an ecosystem?
A. The amount of energy available in an ecosystem determines how much life the ecosystem can support. The greater the productivity of an ecosystem, the higher the number of primary consumers that can be supported. Productivity measures the rate of energy production over a span of time.
Scientists compare the productivity of different
ecosystems by measuring each ecosystem’s net primary
NPP = GPP – respiration by producers
