Question

methane (ch4) is another greenhouse gas just like carbon dioxide (co2). what do these greenhouse gases do?
grow populations
trap energy and make temperatures on earth go up.
help plants photosynthesize
rewatch
submit

Explanation:

Greenhouse gases like methane and carbon dioxide trap heat energy from the sun in the Earth's atmosphere, which leads to an increase in the Earth's temperature (the greenhouse effect). "Grow populations" is unrelated to greenhouse gases' function, and while carbon dioxide is used in photosynthesis, the primary role of greenhouse gases as a group is to trap energy and warm the planet.

Answer:

B. trap energy and make temperatures on earth go up. (Note: Assuming the options are labeled A, B, C with A: grow populations, B: trap energy and make temperatures on earth go up, C: help plants photosynthesize)
