Answer;

A. leaf to mouse

Explanation;

-Considering the fact that the amount of energy at each trophic level reduces as it moves through an ecosystem from the lowest trophic level which happens to be producers (plants).  And about 10 percent of this  energy at any trophic level is transferred to the next level since the rest is lost largely through metabolic processes as heat.

-It means that the lower the trophic level the higher the energy obtained, for instance from producers to primary consumers, more energy is passed since it is the first passage of energy.

The correct answer is option a, that is, leaf to mouse.  

In a food pyramid, the species at the lower level of the food chain directly obtain their energy from the Sun and are considered as the primary producers. This level mainly comprises the plants. The species that are on the next levels are the secondary and tertiary consumers respectively. The level of the energy conversion is the greatest at the lowest trophic level and as one moves up the level of energy conversion gets lower.  

In the given choices, there is a need to determine which of the changes are at the lowest trophic levels. Of these, the option leaf to the mouse is at the lowest level since plant or leaf is a primary producer, and hence, the level of the energy conversion is the greatest in comparison to the other options.

How do plate tectonics explain the formation and metamorphic rocks?
Serga [27]

Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.

When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.
