Answer:
The net annual primary productivity of a particular wetland ecosystem is found to be 8,000 kcal/m2. If respiration by the aquatic producers is 12,000 kcal/m2/year
Gross primary productivity in a region of tropical forest is 1,200 kcal/m-Tyr. In this ecosystem, producers are. 25% efficient. 16,000 kcal/m²/yr

Answer:
Explanation:
option C
Chemical properties, such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form.
Answer:
A neuron receives stimuli consisting of the response of thousands of neurons. Synapse is the signals entering the neuron via junctions called. The role of the synapses are to modulate the signal strength and determine the input signal is either excitatory, promoting the neuron to fire, or inhibitory, tending to prevent the neuron from firing.
At the axon hillock the neuron integrates the inputs and if this total is excitatory then the neuron fires. Although this brief description leaves out much of the complexity, it is still remarkable that out of this web of electrochemical firing units, emerges our very conscious.
Protists are eukaryotic cells while bacteria are prokaryotic.
