Earthquakes on plate boundaries happen more because the plates all move in different directions in a tectonic environment so they collide against each other which makes them more frequent. Earthquakes rarely happen in intra-plate environments but along faults in normally stable interior of the plates. If this doesn't make sense, ask me to reword it for you !
Answer:cacti
Explanation:
In an ecosystem,the ultimate source of energy is the sun. Plants take up this energy from the sun to produce food. Animals eats up plants and when they die ,they decompose. This continuing process leads to the transfer of energy from one trophic level to another in the ecosystem.
Plants ,algae and some bacteria are the primary producers in the ecosystem.they are able to make their own food and support the entire living system. They extract inorganic nutrients and energy from the environment, in order to make their food. Animals(herbivores) eats up the plants and other animals(carnivores) eat up such animals. This situation sets up a chain of flow of energy from the producer to the consumer and back to the environment.

Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.
