Estuaries can experience fairly extreme changes in abiotic conditions. For example, estuaries can at different times be dominated by the ocean when freshwater input from upstream is minimal, or it can be freshwater dominated when there is a lot of flow coming into the estuary from upstream. This means that organisms that exist within estuaries must be able to tolerate a wide range of salinities. These are called euryhaline organisms. Estuary ecosystems also receive biotic inputs from both the ocean and from the upstream river. There are therefore a lot of scavengers that thrive within estuaries, such as crabs, mud prawns and clams. One primary producer group that is important for estuaries are mangroves, but they are not found in all estuaries. Estuaries act as important nursery areas for ocean fish, who come into the estuary to spawn.
When Earth passes directly between the Sun and the Moon, its shadow creates a lunar eclipse. Lunar and Solar eclipses happen with almost the same amount of frequency. Lunar eclipses are more visible because the Earth casts a bigger shadow on the Moon during a Lunar eclipes, but during a Solar eclipes the Moon casts a bigger shadow on Earth so its less visible.
An alligator can have up to 74 to 80 teeth.
The rock walls would be wethered down by the water and would chip off and be grinded down
Answer:
A. Fishing for sea life that lives on or near the shore would be more difficult.
C. The California Grunion fish would have a hard time laying eggs.
Explanation:
The moon is an important aspect of Earth's existence. It influences the change of "ocean tides" <em>(high tide and low tide)</em>. If the moon were to suddenly disappear<em> it will present a number of problems. </em>
Firstly, the tides would<u> all remain the same</u><em> (small tides)</em>. They would also be <em>smaller </em>than the usual tide in the world today. Since the tide will be lower than usual, <u>the marine organisms will not survive living on or near the shore anymore. </u>This will make fishing for sea life in these areas more difficult.
The "California Grunion fish" normally lays its eggs along the <em>coastal areas,</em> which is <em>out of the water.</em> If the tide will be lower than usual, then they will have a hard time going to the coastlines for laying eggs.
So, this explains the answers.
