The answer to your question should be the second option
Answer:
A. two shark populations utilize the same fish population as their main food source
I'm guessing this is from Marine Biology. I know this is an example of competition because two different groups of sharks are eating food from the same source. If one group gets to it first every time, they could leave the other group with no food. So it is a competition.
Educate the general public about activities that can lead to the spread of invasive species.
Answer:
Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.
Composite volcanoes are tall, steep cones that produce explosive eruptions.
Shield volcanoes form very large, gently sloped mounds from effusive eruptions.
Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.
Explanation:
The right answer is vitamin C—citric acid.
Vitamin C or ascorbic acid protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin.
Citrate is a biological molecule found in all living organisms because it is involved in the Krebs cycle (or citrate cycle) to produce energy.
