Determine how much less carbon would need to be realesed by burning fossil fuels in order for the amount of carbon stored in the atmosphere to not increase.

Answers

The carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.

What are fossil fuels?

Fossil fuels (e.g. coal) are different types of fuels obtained from fossils, which release carbon dioxide into the atmosphere when they are burned.

Carbon dioxide (CO2) is a gas that has a greenhouse effect and thus can produce climate warming.

In conclusion, the carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.

Tree squirrels can have different fur colors.

Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur the same color as the trees are harder for the foxes to see and catch.

[IMAGE ONE]
The diagram above shows a population of squirrels that lived in a forest. Scientists had previously only seen brown and gray squirrels in this forest; they had never seen squirrels of any other color.

The diagram below shows how the population changed after many generations.
[IMAGE TWO]
How did the color of the trees in the squirrels’ environment change? Explain what happened to the squirrels over many generations.

Answers

Answer:

The gray squirrels were easy to see and catch so they died quickly and the population dwindled. The brown squirrels were probably almost the same color as the tree so they were harder to see and catch. The remaining gray squirrels ended up having no other options than to mate with brown squirrels, which probably made appear black squirrels and since the black squirrels population raised, means they are harder to see and be caught by foxes.

How the trees became more black too? I have no idea, sorry.

What are the weather conditions?

Weather is the state of the atmosphere. This is the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy at a geographical location. On the Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere of the Earth.

Weather refers to the day-to-day temperature, precipitation, and other atmospheric conditions, whereas the climate is the term for the averaging of atmospheric conditions over longer time periods.

Weather includes the sunshine, rain, cloud cover, winds, hail, snow, freezing rain, flooding, ice storms, thunderstorms, steady rains from a cold front or warm front, excessive heat, and heat waves.
