A scientist is studying an aquarium ecosystem that contains water, plants, and fish that eat those plants. The aquarium has glass walls so light can get in, but it is sealed so no material can move into or out of the tank. When the scientist turned the aquarium's light on, carbon dioxide in the water started decreasing. How is carbon moving and what is happening to the amount of carbon in the living things inside the aquarium? Explain your thinking as completely as possible.

Carbon moving and what is happening to the amount of carbon in the living things inside the aquarium is by photosynthesis.
What is aquarium?
An aquarium (plural aquariums or aquaria) is a vivarium, usually contained in a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish).
According to this question, the aquarium contains water, plants and fish. The glass of the aquarium is transparent and allows the passage of light. Plants are unique set of organisms that have the ability to produce their own food (organic molecule) using the energy from light which they absorb via the Chlorophyll pigment in their Chloroplast. This process carried out by plants is called PHOTOSYNTHESIS.
The amount of carbon in form of carbondioxide (CO2) decreases when the light was switched on in the aquarium due to the process of photosynthesis carried out by the plants.

As human populations have changed over the years, people have altered the course of rivers and other waterways to better suit their needs. one approach has been through the damming of certain rivers. over time, many people question whether this effort has been beneficial. what are the negative impacts of damming a river that are being assessed?
dams allow more water to flow into nearby reservoirs, increasing the chances of disease transmission.
dams cause increases in salmon populations because more water is available for them to live in.
dams reduce salmon stocks, which reduces revenue and overall whale populations.
dams allow for invasive species to move around more easily, which reduces biodiversity.
Answers
Dams allowing more water to flow into nearby reservoirs thereby increasing the chances of disease transmission is its negative impact and is denoted as option A.

A. Extremely positive
B. Exactly neutral
C. Negative
D. It depends on the location.
Answers
The charge of the electrical impulses sent from stimuli is extremely positive. Thus, the correct option is A. The net charge of such electrical impulses is positive because of the positively charged ions of the Na+.
What is an electrical impulse?An electrical impulse may be defined as a nerve impulse that contains an electrical signal which travels throughout the body by the axon terminal.
In the resting potential state, the potential difference is -80mV, while after reaching the electrical impulse it changes to +40mV. This happens due to an electrical imbalance between sodium and potassium influx and efflux.
Therefore, the correct option is A.

Which of the following best describes why in general there are more hares in the ecosystem than foxes.
In 1945 there was a major event that caused the number of hares to dramatically increase. That is why there continues to be more hares than foxes here.
Hares are a lot smaller than the foxes, so more of them can fit into different niches. They can hide better in all of the bushes and behind rocks.
This is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to support the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development
