Answer: Increase
According to the competitive exclusion principle, when two or more species in an ecosystem are competing for the same resource. The one which has undergone favorable adaptation and more competing will be likely to derive those resource than the one which has not undergone adaptation or less adaptive to the environment and less competing. Squirrels and chipmunks compete for the same food source and this food source became scare one of the two species is likely to disappear according to the competitive exclusion principle because the degree of competition between two species will increase.
Answer:
1. As temperature and pressure increases, density increases
Explanation:
The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.
The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
