How does deforestation lead to climate change?(1 point)
Responses
Cutting trees releases stored nitrogen, and there will be less trees to remove nitrous oxide from the atmosphere.

Cutting trees releases stored methane, and there will be less trees to remove methane from the atmosphere.
Cutting trees releases stored methane, and there will be less trees to remove methane from the atmosphere.
Cutting trees releases stored carbon, and there will be less trees to remove carbon dioxide from the atmosphere.
Cutting down trees leads to deforestation, which in turn results in an increase in greenhouse gas emissions. Trees serve as natural carbon sinks, absorbing carbon dioxide from the atmosphere and storing it in their biomass. When trees are cut down, this stored carbon is released into the atmosphere, contributing to the greenhouse effect and global warming. Additionally, deforestation reduces the Earth's capacity to absorb carbon dioxide, further exacerbating climate change.

At a concert, 300 patrons enter the gates in 30 minutes. What is the unit rate in patrons per minute?(1 point)
To find the unit rate, we divide the total number of patrons by the total number of minutes.
Unit rate = 300 patrons / 30 minutes = 10 patrons per minute
Bird seed costs $4.80 for a 32-ounce bag. What is the unit cost of the bird seed per ounce?(1 point
To find the unit cost per ounce, we divide the total cost by the total weight.
Unit cost per ounce = $4.80 / 32 ounces
Simplifying the expression, we have:
Unit cost per ounce = $0.15 per ounce
