In economics resonance use is a linear, then in ecology it will be :
Answer: A
In ecology resource use is circular.
The question contrasts the linear economic model (printed 'resonance use' for resource use): resources are extracted, made into products, used and thrown away, a one-way flow from raw material to waste. In an ecosystem the same matter moves in cycles. Carbon, nitrogen, phosphorus and water pass from producers to consumers to decomposers and back to the soil, water and air, so the waste of one organism is the resource of another.
Carrying capacity is the population an environment can support, capital is a stock of assets, and expansion describes growth. None of them is the opposite of a linear flow.
