Suppose the rate of plant growth on Isle Royale supported an equilibrium moose population of 500 moose. In this scenario, there are no wolves present, and the environment is stable. One day, 200 additional moose arrive on the island. What would you predict the moose population size to be 30 years later? (Enter your answer as a number.)

See the answer below

Explanation:

The population of the moose will remain relatively unchanged 30 years later.

Since the rate of plant growth on the Isle Royale is in equilibrium with the moose's population, it means that the Isle already has the maximum number of moose it can support. Therefore, any incremental change in the population of the moose would be resisted by density-dependent environmental factors and the population would quickly be returned to the equilibrium population.

Hence, unless something changes to affect the stability of the environment, the moose's population will remain stable along with the environment over time.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
