Well once you know the general temperature of the area its pretty easy to figure this out. Tropical climates have palm trees, Mountains have pine trees, if you start to see the birds flying south its too cold for them, things like that
Biological equilibrium, applied to an ecosystem, denotes the state in which the organisms. are in balance with the habitat-type and with each other. Natural Biological Equilibrium is the. state of equilibrium resulting from "natural" processes, i.e., entirely random processes, and is. Is found among Producers, consumers and decomposers.
The so-called bioeconomic equilibrium is reached when net profit is zero, i.e. when the return from fishing is the same as could be achieved from switching to some other form of economic activity.The existence of a bionomic equilibrium(means both biological and economic equilibrium) is discussed in detail and is then illustrated in both numerical and graphical ways. Actually the bionomic equilibria are the points of intersection of the zero profit line with the biological equilibrium line.
